If you don't hear a difference between cables or after burn-in, then don't worry about your cables or burn-in and don't belittle people that do. If you can hear a difference between cable or after burn-in, then worry about your cables or burn-in. It's that simple. My opinion is: if a difference cannot be measured, then that difference is up to debate and interpretation. Do whatever sounds best for you and don't let others' opinions ruin your personal experiences with music and sound.
I have a friend that works at the CERN. He was able to put some of my old Monster Cable in the most powerful particle accelerator in the world on an off shift. You would not be able to believe the difference it made! Now I can hear sounds that were not even on the original recording. Sometimes the wires even pick up recordings from the future. Wonder if I can sell them for $10k...
Speakers can also be worn out due to over use. I have seen spiders that are stretched and will not center the woofer in it's X position, paper accordion edge suspensions fatigued to the point of the pulp coming apart. Older Anico (Aluminum, Nickel, Cobalt) magnets that are 50+ years old are more prone to loosing their magnetic strength due to poor permeability of the magnetic materials back then. Poor damping, weak or boomy bass. You can have the magnets recharged by a machine made for that purpose by companies that recone and/or rebuild vintage speakers. There is break in and a period of life, then end of life. Capacitors in crossovers change value with age and can affect the crossover points and output of drivers due to high ESR. Beware the used speaker if you think you are going to skip the break in period, vintage may not sound like it should due to age. This might be a future topic or brief mention.
I noticed a difference after the speakers I picked up on Cyber Monday had a chance to play for awhile. Speakers are mechanical devices and like all mechanical devices, they need to time to break in to run smoothly.
I've found that phono cartridges have a dramatic burn in as well. I have a Dynavector cartridge that sounds amazing now, but was horrible during the first one or two days of use. Somewhere around 10 hrs. of playback the high end calmed down and smoothed out.
This is very consistent with my perceptions with breaking in guitar speakers. I buy one, install it in an amp and play if for an hour, and there is a hardness or strident tone that bugs me. My trick is to take it to the workshop, plug a drum machine into an amp (turn the bass down since it's a guitar speaker), and leave it for 48 hours! Yes, there is a noticeable difference, and you can tell that it continues to get better after numerous hours of playing. Brent Mason, Nashiville's most recorded session guitarist, noted in a video that guitar speakers blow right when they're sounding their best. Burn in is real - just like breaking in a new pair of shoes.
Interesting. I purchased a new set of LS50s and returned them because I didn't like the sound , several years later I bought a used pair for an excellent deal and they sounded great , I always thought it was my changing tastes not the speakers , but burn in may have been a factor also.
And I’ve just bought a set of ELAC Navis on eBay that were returned to the shop by the first buyer. I was a little worried there could be some issue with the pair as reviews have been very good, but the 40% discount to MSRP was too good to pass. Took delivery, hooked them in and it was a pretty big disappointment... I have to say these were the first good speakers in my new house and our living room has a weird setup that doesn’t really suit audio (L shaped with roof arches), so I thought that could be it as well. Nevermind, I can’t even tell my wife the (discounted) price so forget about reselling them immediately - I just had to stick with them for now. Well, it’s been a couple of weeks and, man, what a change! Even certain parts I thought were due to the room, pretty much gone! Loving the speakers and pretty glad I got a “good deal” on them! I guess the first buyer should have given them more of a chance. NB: today added Isoacoustics mini pucks between speakers and stands - I am now in complete awe and listening way too late into th3 night!
m m Yes, very clearly! In particular the bass and mid-bass frequencies are a lot tighter and the sound is generally cleaner. Mind you, the speakers were resting on spikes (bottom and top of the stands) but they have rubber underneath them, so that was definitely not ideal (coupling to the stands but not like if screwed - either too much or too little coupling if you know what I mean) and I was going to replace the spikes with sorbotane (rubber) pods. In the end I decided to go for mini pucks (Orea is recommended but way above budget) and I am so glad I did!
I remember setting up a new stereo for my parents some 15 years ago. My mom thought the speakers were a bit harsh and sharp sounding when she heard them first. Played them all day when they were at work and I at school. Gave them a good beating on the volume whenever I could, before they got home. After a couple of days I asked them to sit down and listen again. Wow! Gone was all they complained about. Asked what I changed on the settings? Nothing!, I told them ;-) My experience: Some speakers it has a huge impact on. Others only minor, but they all have a noticable difference before/after burn in (unless we speak very cheap or shitty bluetooth speakers etc.). Electrical burn in on CD-players, amps, cables etc I don't believe much in as I have never heard a clear enough difference to verify it.
Woofer cone is stiff until used for a while. I hand pumped one after a year's use and it was easy to pump. I then bought another exact same new driver and it was really hard to hand pump. Objective evidence!
If you have electrolytics in the signal path, you will absolutely hear a positive difference after some hours of burn in. Ive noticed this with particular metalized film types like the red/yellow polyester wima caps too. The red polypro wima's sound considerably better when new over the red ester WIMA's, but imho, the polyester wima's sound better then the polypro when both are compared after 100 hours of use or so. With top quality film cap types i havent really noticed a burn in period or significant change through time, that is unless being used for the output filtering on a class D power stage. It really does seem like ALL class D power filters need a solid break in period to perform their best. I've yet to play with a brand new class D amp of any variety/manufacturer/price point where this wasn't the case. Even PS audio takes a significant time/profit hit to give long burn-ins to all their class D filter designs for this very reason. It's so the very large high voltage rated capacitors can form under exposure to the heat and current the signal produces. Forming DOES indeed even apply to quality film types if they're physically large enough or if the voltage rating is fairly close to the intensity of the signal passing though it (1 or both apply to basically all class D filters), at least in my own personal experience.
I have never had a pair of speakers not do exactly just what you are stating. Most get burned in from a weekend to two weeks. Solder changes will also benefit from some burn in. This has been for around 50 pairs of speakers from $6k to $250k. I have a play list of a dozen songs, many I played on guitar when I was younger, to compare how they sound. It really does sound different with time. Thanks and keep up the good work. Oh and I'm using a Clio FW but I have only tapped a 10th of its potentual.
I have had many Speakers that didn't change much with break-in, but recently got a pair of Floorstanders that actually opened up after a surprisingly long period of break-in...
The commonly held belief is that all aspects of sound can be quantifiably measured. This really is naive because new ways of analyzing and measuring are still to be discovered. They never used to measure transient inter modulation distortion (some still don't) of speakers. I have experienced break in of speakers, but after my last capacitor upgrade I feel that caps may be even more significant in the change heard during break in than drivers.
One of the most profound break ins that I have heard was after recapping my amps; almost unlistenable to amazing, I wasn't expecting anything like that.
Funny thing. I always said these people who think their speakers need burn in are crazy! There is no way! Then, a couple weeks ago I bought some new speakers. Hooked them. UGGGHHHH. Horrible. No bass tinny sounding crap. What a waste of money. Two songs later....hmm....a couple more songs.... exactly what I expected. Great speakers. Who knows how long they will improve for but I am now a firm believer in speaker burn in.
@dalechalfont112 well if you are churning out multiple speakers a day in a big factory, the logistics of a room of amps and sinewave generators to burn in every speaker in the day's production becomes cost prohibitive.
I had some older speakers that sat unused for about 10 years. When I set them back up, they were very harsh. I just use the system for listening to music while I work at my desk. Overall, I switched from CDs + reciever to my computer streaming (Spotify) via blue tooth to a cheap Class D mini amp. In the past 2 weeks (a few hours a day) of using this setup, it is starting to get back to sounding good. Harshness is vastly reduced, but I wonder if the BT + cheap amp have become the limiting factor to the sound getting better. Guess I could always dig out the old amp, run some wires, and give it a listen. But then, that equipment also sat for 10 years.
I bought a set of klipsh rb81 bookshelf speakers . they sounded awful at first but after 100hrs or so they really changed .they are now one of my favorite speakers .
I've owned Klipsch Forte III's for 5 years. Probably have thousands of hours on them. Just purchased a second pair as a backup because I dislike the phenolic driver in the Forte IV. Plugged them in to make sure they work before packing them back up and storing them - they sound exactly the same brand spanking new as the ones that are 5 years old.
I agree to all you said. I made a test the last couple of days ago. In my cab I had a fairly unused speaker. I hooked up a sound source and let it run for about 16h. I covered the cab with all I had because of the neighbours. It is a 12 inch speaker and my thoughts were it has bigger components. That means everything is a little stiffer. I choosed dynamic sound at decent volume. What happened it sounds not much better now but a little more midrange. But I won`t let it run 24/7 now. I was just curious about what effect it has. Too many opinions of how, length etc.. I even had a sound room very close that is completely isolated. No reflection at all. The purpose is not for speakers but sound of any components they want to check. It is GE now. I took a noise test gear once of them to test the noise of my bike. Long time ago though. Anyhow, thanks for the facts.
I built some 2 way speakers, used them for a year and took out the 8" driver and hand pumped it fairly easily, before putting the driver back in the box. I ordered another brand new (same) driver (for another set of speakers). When the driver arrived it was so stiff that l would have wrecked the paper cone before it would hand pump. It would obviously take way longer than ten seconds to free up the cone. Iol Obviously they don't make speakers and don't hand pump drivers either.
When I completed my first pair of DIY MTM's I thought I did something wrong lol. They were thin and harsh. However, over time they did sound better and easier to listen to. By six months I was over joyed! I find it funny how opinions on the internet have got to a point where talking about loudspeakers has become a battle of sorts.
Just an observation. I haven't ever heard of anybody saying that after burn/break in, their equipment sounded worse....only better. Not arguing if burn in is real or not, just something that I noticed
I believe the harshness has more to do with the capacitors in the crossover forming. Has anyone noticed harshness on a full range driver without a crossover?
I have read about some CRAZY burn in times for Magneplanars - the website mentions a "burn in period" but does not specify a particular time window. People talk about 200 to 300 hours on forums but who knows where that originated from.
@Cliff Moore - I find lead guitar solos, or any kind of dynamic rock music for that matter, lacking on Maggies. That's the reason I don't own them because on classical and instrumental and vocalist genres there's nothing better than the mighty Magneplanar. If they ever come out with a Magneplanar that will do prog metal justice I'll make the switch.
@Thomas Andersen yeah true dat! Also you can compare dealer demo to new pair. For example when your new speakers arrive if same finish. Ask dealer to set them up or not while you are out of the room listen to your one song you are familiar with. Out of 10 times see if you can identify the new pair and the one which is the demo. I can tell you my new pair of Monitor Audio Gold 100 5g sounded pretty good right out of the box.
@Thomas Andersen I'm not familiar with that brand but like I said you have to do controlled test to be accurate. The only true way is to isolate all variables and used a pair that is broken in compare to new pair. So play new pair for say 70 hrs. If you can identify 10 out of 10 times between the two pairs. And then move onto 160 hrs. But if you can't identify after 70 hrs then the rest is possibly subjective. BTW you can listen for differences as long as you want no pressure but you can't be in room when they cycle between the two set of speakers.
Hello from Canada! Great informative video and thanks for all the hard work and countless hours you put into your videos. I have a pair of Energy Reference Connoisseur 30 (rc-30) speakers. I bought these used for $200.00 CDN off a guy that never used them because he didn't like the sound. He only had about 10-15 hours on them. I have about 120hrs on them and they sound great and keep getting better. Is there any tweaks or changes that can be made to get the most out of these? Thanks again for your videos.
Speakers are electro mechanical systems and all mechanical components needs breaking in. Think of engine pistons and cam shafts, they need to run in for at least 1000 kilometres before you can ramp up the revs and drive at high speed. Woofer cones and tweeter domes needs flexing before it becomes smoother as new materials are quite stiff at first.
Thanks for the explanation. I can agree because I have done lots of burn in / break in with equipment cables tubes, etc. Just a few tips; I have found the burn in CDs help greatly, but total playing time is still important. 2. Speakers need the power input to fully break in. 3. Vacuum tubes break in very well with tuner/ radio noise from between channels. 30 min. to an hour is enough for the tubes. Works much faster than a burn in CD. Cables respond well to "cable burners" which you hook your cables to. Be very careful with home made burn in devises. They can be dangerous (not worth it!).
I don't know if it was my ears or my speakers, but the ones I just got a few months ago sound much different than they did at first. 🤷 At first they were a little more tilted on the top end, had a little more sparkle. A little more harsh as Danny said. Now they're a little more smooth, a little more creamy, a little more easy to listen to.
Whichever 3 people disliked this video, please just stay off the channel. This is as good an information piece as you will find on this subject, containing facts from someone who knows his shit.
Since one personal event i experienced, (still my biggest ever speaker break-in awareness event) i care nothing about what speaker break-in deniers say: In my 1980's stereo days, i bought a pair of 3 way s/h German speakers (Schneider) with newly installed replacement 12 inch woofers, the seller told me "they may need breaking in" & the science behind the notion made sense to me tho i never expected anything like what happened before or after. When i got them home, i put them on my otherwise familiiar stereo system & heard next to no bass. Utterly dissapointed, the next day i heard almost next to no bass & they still sounded awful with a massive defecit below 400'ish Hz. I wired the speakers out of phase & placed them facing each other with a 6'ish inch gap inbetween for max' sound cancellation, (i only required physical cone- movement) I put an awful new-age type c.d. with very mega-deep synths that droned & modulated on & on ad-nauseum, (it's bass was normally so deep in bass & subsonics that i'd use it as a test-CD for subwoofer setting) I left that on repeat play & left them playing like that in the workshop for about 5 days behind closed doors. When i put the speakers back to their original playing positions, i was very pleasantly shocked! the speakers had all the bass i could ever wish for, nothing close to what i heard on my first 2 day's listening. I cannot be convinced otherwise that those particular new woofers went through a massive improvement & had a real & deep & more powerful bass compared to the wimpy lack of bass as when i originally heard them when new. Maybe speaker break-in can be more or less noticable depending on surround material's elasticity, shape-memory & design but the difference before & after 7'ish days constant break-in was massive in my case.
I do like to let my new speakers break in before I sit down and listen heavily. It's because I want to be able to write an objective review of what they really sound like. My BIC Venturi DV84's and DV62CLR-S's sounded different before break-in, the tweeters had this crispyness that went away after break-in. The port noise on my JBL Studio 530's seamed to calm down a bit after some break-in time. My new JBL Studio 590 towers seamed to have kind of anemic bass at first, but since they've racked up some hours, the bass does now sound firm and freaking awesome!
Any "burn-in" that happens, mostly happens between your ears. I've experienced this many many times. No change in measurements but I "grow to like" the sound or I don't.
Then would you like to explain the changes that are easily measured? You can see them here: www.gr-research.com/burnin.htm www.gr-research.com/myths.htm
Maybe true for your ears. I do my burn in while I’m not home. The change is distinct. Huge difference in harshness and glare. Listen for five 3-5 minutes every 24 hours. You will get it.
@@mickywes3733 If such a huge difference appears so quickly, how come the sound doesn't change after that? I understand that everything should "settle in" , when talking about mechanics or electronics but if big differences happen in such a sort span of time, shouldn't it happen all the time? I mean, if burn in actually makes differences that can be heard, then burn in a pair of headphones for let's say 20 hours. Just put them somewhere with a long playlist, crank the volume and don't listen to them. Let's assume something significant happened. When we start to listen, sound may still be "harsh" or whatever and after a while you might grow to like it or not, it changes still even though nothing is happening electronically that should explain this. Did I make myself more clear now?
@@OjStudios no, not clear. Sorry. However, speakers that sound harsh or glaring or whatever because of design, don’t start to sound better as your ears adjust...they sound worse as ears fatigue. Speakers that sound harsh at first but burn in well, will be unpleasant and fatiguing at first but become smooth and comfortable as they burn in. If you can’t hear it then it shouldn’t matter to you, but that doesn’t mean it’s not there.
@@mickywes3733 What you just said didn't make much sense. If something is harsh by design it doesn't burn in but something that burns in well changes.. Right. What makes something burn in well? If something is designed to change drastically in few hours of it's use, why it changes just in the first few hours and not anymore after that period? If this would be the case, burn in would've been done already at the factory to hook the buyer with better sound. What kind of manufacturer wouldn't want to give the best first impression? Some speaker cones and cabinets are made of wood which does change it properties, because of vibrations the pours open up. Happens in cellos, guitars, violins, a bit in pianos etc. Speaker cabinet is designed not to "sound like anything" kind of. Material and shape of course plays a big part but rigidity is a bigger part. Not thin walls like on wooden instruments.
No technical quantitative information I notice. This is simple, the physics is entirely understood, no need to measure. In particular, if there is a burn in effect, it must be designed into the speaker, so the effect will be absolutely known; the alternative that it is not designed in is unacceptable and suggests the improvement, rather than progressive worsening, in every speaker is just a random bonus. Either burn in is designed into a speaker so every manufacturer could show us the change with time, or we believe it's a happy coincidence that the unconsidered burn in always happens to be a good thing. I know what I think, and as a neuroscientist I will tell you the brain can become accustomed to the most extreme perturbation of the senses.
And more bass cos the cones free up. I hand pumped a well used driver and than a new (same) driver and it was way harder to hand pump. Objective evidence!
Heres what I know...The longer you listen to a speaker, the more you get used to the sound. Things that bug you can fade, but it works both ways, some things you really enjoyed start to lose there sparkle. Chasing the dragon. As far as burn in, I can see it making a small difference. I also don't think you should rely on burn in the enjoy a speaker, if you dont like it, and someone tries to tell you to wait for burn in...just find another speaker.
I would think that a broken in speaker would give better low end, since it’s easier to move the cone further with less effort. Guess the damping factor of the amp might affect that, though.
So basically, from the speaker driver's mechanical point of view, the change is to the transient response of the driver suspension, with softening of suspension effectively improving damping ratio.
Guitar stings change dramatically over the course of about ten hours of play. At first they are bright then they soften up to the point were they are almost unbearable to play. They really only last for about 30 hours of play. When you read a new book the pages are hard to hold until they soften. Speakers are most definitely the same way. Duh.
After all this, the question boils down to one simple thing: it stands to reason that after an internal suspension of a speaker starts to move, everything will be different, perhaps softer. What no wonder. I find this very natural, just as in any other physical circumstance we find in our daily lives. Why such a fuss about something we are fed up with in our lives?
I don’t really believe in speaker burn in. BUT ... recently I got the LS50. Plonked it into my main system and it was okay sounding. Realized the highs weren’t all that smooth. Was not that impressed. Not bad speakers but sounded ok only. So I put them in the bedroom for casual listening and TV duty. Now after a couple of months later, I take them to the main system. Yeah ... it sounded better. I also got the RP 600M earlier on. Stuck it into the main system and it sounded ok. After a very short listening, I decided to burn them in. So placed the speakers facing each other, reversed the polarity for one. After 10 hours or so, I put them back into the main system. It sounded different. So ... I am starting to believe that there is some effect.
As Ron said, "They ride their tricycles up to the computer and smash the thumbs down button..." Lol... He's spoken to their parents about this problem.
Anything mechanical in nature from engine systems to loudspeakers to more or less degree, It all has a wear in period. Anyone whos purchased a brand new atv or dirt bike from a dealer, or bothered to ask while buying a new car, has likely been informed NOT to push a brand new engine hard until "x amount" of gallons of gas or x amount of miles have been driven. You can genuinely straight up damage the cam's and piston housings in the heads if you push an IC engine too hard too soon. Machines have to wear into their spec'd performance, it doesnt matter what kind of machine it is, and a loudspeaker is a good example of a linear excursion motor rather then centrifugal excursion motor like a DC electromagnetic motor or something. It's still a motor, it still functions hrough mechanical excursion. While im at it, ill go ahead and mention that capacitor heat forming is a very real process, that we also like to call "burn in" and is a very understood process. Capacitors perform differently once exposed to voltage and a bit of heat and they (especially electrolytics) are designed to form into their spec'd values and fill the microscopic conductor pitting inside the dielectric evenly, and this is why they sound different new. If we were to make brand new electro caps at their rated values, they would burn in and settle outside of spec after forming to their conductor pitting. The ONLY way to form a capacitor is to pass signal through it and generate a small amount f heat for an extended period. This usually isnt done outside absurdly high end audio products before selling because it would be a very time consuming and costly process just to do something an end consumer will do on their own anyway. It doesn't matter what way you slice it, burn in is real. Go by a brand new copy of ANY product you have owned for a while with moving parts or electrolytic capacitors in it, thats still being made and use it. ANY product, electronic or otherwise, doesnt matter, and tell me it feels and performs the same to use as your worn in product, if you do, you are lying to me. It may not be better, but it will absolutely 100% feel different. There is nothing sold on earth with moving parts, or electrolytic capacitors, that doesnt go through some kind of wearing/burning in process. Doesn't exist. Hell, most things even without caps and moving parts still wear in too. Even a well used wooden soup spoon feels different to use then a brand new one, and i prefer it 10 fold to a brand new one... Idc what Joe-Gaming-Chair has to say about it. Whether its electronic burn in, or physical break in causing operational parameters to change, or wear and tear causing something to act differently then when it was new, it's not just real, its unavoidable, and it applies to basically every product that exists. If you think your brand new loudspeakers will still sound the same 30 days into using them, you are sorely mistaken. If you think your power amp you bought last summer still sounds the same as new. An a/b with a new unit will show you that you are mistaken in your assumption. You'd probably be glad it doesn't sound new anymore, honestly.
Yup. Breaking in a new pair of DFR-52s right now and when I first plugged them in last night, they were unlistenable for music IMHO. Flat, unclear across the spectrum. Good for TV watching and that's it. I left them with pink noise overnight at a medium volume level (... and my bedroom door closed.. lol) for 8 hours. They were where I would expect them to be this morning. About 50%. I ran them through some test tracks and actually could enjoy and get into some music. But the soundstage is still not really 'there'. The clarity is better, but the complete 'wow' factor is just only just beginning to creep in. Still fun to listen to, but with room for much improvement. I guess what I'm trying to say is that the burn-in factor is OBVIOUS to anyone who considers themselves an audiophile. I would define a basic audiophile as someone who acknowledges and appreciates 3D soundstage - byond all the other base parameters of FR and voicing. Once you tune into that, you're done like dinner and there is no return. :) @ NRD/Danny - You can't just run of a bunch of stats and provide zip. Danny you're just talking about measurements without presentation of the data. A great start, but show our work.
The tough things about these tests are (1) how to know the degree to which these measured changes are picked up by the typical ear and brain, (2) controlling for the familiarity effects that make the drivers sound more appealing to the brain over time, and (3) reconciling these studies with other studies, such as those done by Joe N' Tell, that show no changes in performance over time. in the end, it makes no difference, really. if you buy a pair of speakers and don't like them, just play them more (maybe a lot more), and see if your views change. In the grand scheme of things, 200 hours on speakers that you may keep for 20 years isn't much.
Ron, question. Do you know if powered speakers go through burn in? I happen to hear some Klipsh Speaker 5's that to my ears sounded incredibly the only thing I found lacking was Treble extension though there was Treble it was an exceedingly fast roll off is how I would discribe it. I did find the Mids and the air almost Hallowgraphic the Bass was a tad meaty, but acceptable l'm sure I could find my happy space. The Bass did seem fast, but not lightening so. If it was just as present in my room I'd doubt I'd need a sub. Though I'm also certain it would help to open the already seemingly good Sound Stage. Thanks Regardless.
I left my (Genius generated) new speakers on for two weeks at moderate volume when I left for an extended period. That's the equivalent of about two months of forty hour weeks at work that they played. Nada. What bothered me initially continued. Break in is not a panacea. It may work.
I agree the spider in the woofer has to be worked in a bit. It's the most Rigid when it's new.and gets softer or more brittke with age . Also magnetic flux density changes over time. I have old Alnico speakers that need to be re magnetized again.think of it as an electric motor. There is a break in period. Especially with DC motors more than AC motors .electrical mechanical and chemical fatigue. Caps wear out could get overheated and insulation wears out. Paper rubber plastics all wear out and change with time
I appreciate your comments . . . it isn't about always being right; however, it is about having the freedom to disgust and debate without personal attack. Unfortunately, the ideology of today has unfortunately become: if you don't agree with me, then you need to be censored and silenced . . . that doesn't work for me as I am not politically correct -- never will be, and have a mind of my own. Please keep posting your videos, for it is ideas that encourage everyone to THINK for themselves and to know what they truly believe. I appreciate your generous spirit and your ethics in business.
My personal limited experience is that moderate and even quiet, even very quiet works for burn in. BUT, that’s all I have done. I can’t compare it to loud burn in.
Very good job here on discussing the mechanical aspects of frequency burn in and Danny’s test to prove it. Actually quite scientific and even included the comments concerning the water fall test showing this-which does mean a frequency test difference. The “proof” of capacitor burn however had no facts presented. Overall well done though.
Thanks you and Danny for presenting this. Fantastic scientific measurements. I trust Danny for his many years of building speakers. I really liked the 10,20,40,80 analogy. And diminishing returns as time goes on as to break in.
After "the burn in" period the results should stabilize but after a longer period say a year or so do the test results actually show a decline in performance Danny please test
Any audiophile who utters the words "flat earth" in referring to his critics instantly loses all credibility. Let's quote GR's own article on break in: "Obviously, as a woofer is played over a given time period the suspension compliance changes. This objective data showing changes in the T/S parameters as the suspension loosens up *** does not prove noted subjective differences in the perceived output, or how a speaker sounds, *** but does prove that there is something more taking place than getting used to the sound." Their own conclusions, in summary are: Something changes, but the changes are so minor that they make no difference to how a speaker sounds. But of course, they have to lean in heavily on the whole "something more" angle, to justify their profit-preserving break in advice, which in the end is nothing more than a tactic to convince people to keep a product long enough to build sufficient cognitive bias to prevent product returns.
Prove it! Do a live blind comparison of exact same speakers - one out of the box and one 6 months old. Then choose the best and change amp/sources. I see reviews and conclusions on $10k speakers out of the box--Boernicke, GoldenEar, Magnepan. Prove that the sound actually softens over time with fixed variables.
I noticed that the intro pic for this tech talk has a JBL Studio 530... i have a pair and like them a lot. Any thoughts or feedback from your standpoint? Have you listen to them?
Car audio guys know this . Especially in the spl subwoofers you notice them get softer over time . I'm sure this affects the amplifier and the sound quality because of Q and box port and airspace Changes as the spider (mostly) Loosens up and the voice coil winding gets heat cycled
I can believe theres burn in just like New Shoes get better when you wear them awhile and a New Car engine runs better after a few miles of wearing in, one thing I cant believe is buying super fancy cables for a home stereo just get some good thick lamp cord youre good
Rex Holes, you believe shoe's, and engines, because you have owned them yourself and experienced it for yourself. But have you ever owned a nice set of cables to experience it yourself? If not, then you haven't really experienced it yourself. Which would mean that your opinion on cables mean nothing.
Question: At higher frequencies the diaphragm flexes, wouldn't this flexing change the characteristics of the material over time? Wouldn't that affect the decay?
Nothing wrong with the topic. Nothing wrong with putting forth theories and explanations. But don't denigrate blind tests. The gold standard is what can actually be heard. And to remove the power of suggestion and personal subjectivity, put the speakers behind curtains. That takes some effort. Also, don't do the same thing you complain about from others. They dismiss assertions that speaker burn-in is a significant phenomenon. You dismiss the idea that your ears can get used to something. Equally unacceptable.
I wonder if you would have time to do a video explaining the effects of boundary gain with ported floorstanding speakers vs sealed bookshelf? I bought some expensive floorstanding speakers and have found that the bass is boomy due to the 34hz port frequency. This excites room modes and I now regret my purchase. I feel I should've bought some bookshelf speakers instead that roll off at say, 70hz and let my sub take over from there. Is this something you would consider covering in a future video perhaps? Cheers, Mike.
@@greggcheap6208 Hi Gregg. Yeah, I've inserted some porous material inside to still allow some air to flow but it still causes a huge bass bump. Tried completely sealing it too but I found the bass/midrange driver started to make strange noises so it's clearly not designed with that in mind. The port it a large rectangular outlet on the bottom rear so isn't a standard reflex port. I'm currently considering the Harbeth P3ESR as an alternative which will allow me to use my subwoofer high level input to let the sub do all the low end grunt.
@@greggcheap6208 The problem I have is that I live in a typical English home. 3 bedroom semi-detached and my lounge is only 4.6 metre x 5.2 metre with a 2.6 metre ceiling height. Not ideal really. Unlike most American homes where the lounge is huge! 😎
@@greggcheap6208 Hi Gregg. Unfortunately no, it's a two way design so just tweeter and woofer. Look then up: Spendor A7. 👍 Fantastic speakers and sound sublime but need room to breathe which I can't give them. 🙁
Jeez. Of course things break in. Especially mechanical things. Your new car needs to be broken in, your recliner needs to be broken in, your baseball mitt needs to be broken in, your shoes need to be broken in. Anything fresh off the factory floor needs break-in time. A speaker's natural tendency will be to remain motionless like all inert objects. My Mrs. will tell you it took a long time to break me in.
Does anyone know if speakers are burned in at the factory and which companies if any do this? I don't understand why if it made improvements they wouldn't just do it there and save us the hassle.
in the early 1980's I had purchase a pair of Advent Maestro 3 way loudspeakers. I powered them with a Proton D1200 amplifier. When I first played them they sounded very good. I had a friend and neighbor over and we listened at pretty high volumes. A few hours in these suddenly began opening up and playing louder. This actually happened very rapidly. My friend and I both listed to it happening at the same time. he and I were both amazed as I don't recall this happening in the past. I too believe in burn in/break in.
I had something similar with some Kef Coda 8. In the first couple of hours I noticed the soundstage get wider, with just a bigger, more immersive sound overall.
You always can tell the guys who got an F in physics and material science. Or they were the guys who have a good memory and get an a on the test but absolutely understand and know nothing they’re getting an A for. 😂 flat earthers do usually the same guys who became supervisors or managers, Clueless
question I viewed a youtube video not sure who was possibly 123Toid or Impulse Audio were they did some testing on a driver new vs 40 hours of burn in. There was a decent size difference in the freq vs impedance response measurements after. The flat earthers have a real problem on their hands now lol. Is 40 hours enough and does this vary from model to model of woofer ? It would suck to take acoustic measurement for purpose of cover design just to have it all be way off six months after the build is dome.
That Gene dude belittled/slagged off Steve Guttenberg awhile back because he didn't agree, not long ago that same Gene dude did the same at an audio show and lost a sponsor, lol karma is sweet
Well some people believe you don't have to break in a car engine either , and yet the manufacture pre programs the cars computer to not give you its full horsepower till after 500 miles !!! HMMMMM I wonder why !?! And if there is no such thing as break in , how do speakers wear out !?! I guess you can't educate people that refuse to learn , but you gave it a solid try !!!!!
Ok if you want to believe that , but the voice coil and magnet 🧲 assembly are moving parts and let’s not forget the spiders etc 🙄 and if there is no friction why do the voice coils get hot and good speakers 🔊 have them vented 😱
If you want a woofer with next to no burn-in time and a ridiculously low FS get one with a foam surround. Of course, it will disintegrate in a few years but hey... Fortunately - foam surrounds were mostly a 70's and 80's fad (thanks for that, JBL)
Foam rot was one epidemic, many such speakers put in the hard rubbish, I used to kick the foam rot woofers in or take em home to blow up, The Realistic Optimus 650s and my dad's first speaker pair (no name cabs with Foster drivers) had been given rubber surround kits to save them from demise
I remember when I purchased a set of b&w 803N's and my god did they sound horrendously bad for the first 100-200 hours! Burn-in was dramatic as hell. The owners manual said that burn-in was around 10-15 hours. Man was that wrong! I think b&w has since made improvements to eliminate this horrible phase (that never returns) But I have owned all kinds of hi-end audio components that did this, and they were all great products.(once they broke in).
The parts of all NEW mechanical devices need time to "settle in". The manufacturer of your brand new automobile tells you to drive carefully for the first 500 to 1,000 miles. The LAWS of PHYSICS are undeniable.
@MAD GRUMPYMAN Very interesting video showing MBL speaker assembly, unfortunately I will never be able to afford any of their products. I think I can find happiness with my new MAGNEPAN MG.7s.

I knew about speaker break-in before I was even exposed to the idea of it. Back in the 80s bought some bookshelf speakers that sounded like crap and almost returned them, but kept them in my system for a few more days. And lo and behold they were magically transformed. Only later upon reading speaker reviews I knew the phenomenon was legit.
It’s also possible something like this is just due to you adjusting to the sound, as well. I think both things happen. When we first listen to speakers we have an idea of what we are looking for and if it comes off differently than what we expect, I think it takes time to really hear everything as it is.
@@weeooh1 Of course! I've followed Danny's work on this since he initially wrote that part of his website. It's a complex subject though due to how the ear operates. It's very sensitive in some ranges, very insensitive in others. Proving something is measurable is different from proving something is audible.
If Heavyweights like Dynaudio state burn-in happens and even do it in-house when they design them also I've seen measurements with difference in T/S parameters from diyaudio enthusiast Göran @ audioexcite(although I think he works for a speaker company now) who am I to disagree with them what would be the point of them lying. Would make a few fun videos of Dani to look at the works with commentary of some of the more renowned speaker builders in the diyaudo community(most notably Troels , Goran & Zaph ...i`m sure there are many others but these come to mind)
you're just getting used to hearing a familiar sound over time and that makes you like it more over time. there is no Burn In for any audio equipment at all
Always interesting to hear different opinion's on this topic. I will point out though that there is something to gain from a manufacturer's point of view. It's very convenient to tell a customer who doesn't like the sound of their new speakers to just keep them instead of returning them and they'll sound better over time.
Oh so for this discussion measurements matter but for speaker cables they don't? Convenient... Yes, speakers and electronics need burn in but lets be consistent…
I bought a pair of paradigm 800Fs brand new and was disappointed in their sound at first. Compared to the infinity QLS1's I grew up listening to, they were not great. I was instructed to put on some music, leave the volume up and leave the house. I did that, let them play through some rock, heavy metal and classical repertoire for 10 hours. Did that for 2 days while we were visiting family. Sounded like completely different speakers when I sat down to listen to them again. I love them now, so happy I got them. EDIT: it may have been the Denon Pma-800ne that needed the burn in. Couldn't tell you.
Who can win anything with appreciations that reflect only a lack of technical knowledge? Wake up and accept things as they really are. Want to do something positive? Turn on your new speakers, drink a nice bottle of red wine, let the time pass and let nature do what it naturally does. The rest comes with time, as it always has been. Forget the fucking measurements on frequency and if you don't like the result, get another speaker set until you're satisfied.
So, regardless of viewer’s comments, do these readings that he sees in his testing translate to audible improvements that those who don’t have “golden ears status” can hear?
I did not believe in speaker burn in but now as I bought some high grade new speaker I experience is right now. I was suprized and could not believe it, so I talked to my dealer. He said it is true, there is a burn in. Just to make it clear, there was no talk about burn in before I bought them, so this was not a marketing scam to me. After one month they changed, I have trained ears, being a pro musician all my live.
Really nice video. Thank you. Danny is getting better and better in front of the camera and Ron is getting better and better at pushing as many ads as he possibly can in a single video. Thumbs up anyway.
If you don't hear a difference between cables or after burn-in, then don't worry about your cables or burn-in and don't belittle people that do. If you can hear a difference between cable or after burn-in, then worry about your cables or burn-in. It's that simple.
My opinion is: if a difference cannot be measured, then that difference is up to debate and interpretation. Do whatever sounds best for you and don't let others' opinions ruin your personal experiences with music and sound.
If you can't see the noodly appendages of the flying spaghetti monster blessing your life, leave me alone to spread the good word to others who do!
I have a friend that works at the CERN. He was able to put some of my old Monster Cable in the most powerful particle accelerator in the world on an off shift. You would not be able to believe the difference it made! Now I can hear sounds that were not even on the original recording. Sometimes the wires even pick up recordings from the future. Wonder if I can sell them for $10k...
LOL
Nah I'll keep making fun of you. Thanks for the suggestion though.
Speakers can also be worn out due to over use. I have seen spiders that are stretched and will not center the woofer in it's X position, paper accordion edge suspensions fatigued to the point of the pulp coming apart. Older Anico (Aluminum, Nickel, Cobalt) magnets that are 50+ years old are more prone to loosing their magnetic strength due to poor permeability of the magnetic materials back then. Poor damping, weak or boomy bass. You can have the magnets recharged by a machine made for that purpose by companies that recone and/or rebuild vintage speakers. There is break in and a period of life, then end of life. Capacitors in crossovers change value with age and can affect the crossover points and output of drivers due to high ESR. Beware the used speaker if you think you are going to skip the break in period, vintage may not sound like it should due to age. This might be a future topic or brief mention.
Spot on I have seen the same effects on older or second hand speakers
I noticed a difference after the speakers I picked up on Cyber Monday had a chance to play for awhile. Speakers are mechanical devices and like all mechanical devices, they need to time to break in to run smoothly.
I've found that phono cartridges have a dramatic burn in as well. I have a Dynavector cartridge that sounds amazing now, but was horrible during the first one or two days of use. Somewhere around 10 hrs. of playback the high end calmed down and smoothed out.
You are correct, sir! Anything mechanical will change over time, and that applies to a phono cartridge. You can't change physics!
This is very consistent with my perceptions with breaking in guitar speakers. I buy one, install it in an amp and play if for an hour, and there is a hardness or strident tone that bugs me. My trick is to take it to the workshop, plug a drum machine into an amp (turn the bass down since it's a guitar speaker), and leave it for 48 hours! Yes, there is a noticeable difference, and you can tell that it continues to get better after numerous hours of playing. Brent Mason, Nashiville's most recorded session guitarist, noted in a video that guitar speakers blow right when they're sounding their best. Burn in is real - just like breaking in a new pair of shoes.
Interesting. I purchased a new set of LS50s and returned them because I didn't like the sound , several years later I bought a used pair for an excellent deal and they sounded great , I always thought it was my changing tastes not the speakers , but burn in may have been a factor also.
And I’ve just bought a set of ELAC Navis on eBay that were returned to the shop by the first buyer. I was a little worried there could be some issue with the pair as reviews have been very good, but the 40% discount to MSRP was too good to pass. Took delivery, hooked them in and it was a pretty big disappointment... I have to say these were the first good speakers in my new house and our living room has a weird setup that doesn’t really suit audio (L shaped with roof arches), so I thought that could be it as well. Nevermind, I can’t even tell my wife the (discounted) price so forget about reselling them immediately - I just had to stick with them for now. Well, it’s been a couple of weeks and, man, what a change! Even certain parts I thought were due to the room, pretty much gone! Loving the speakers and pretty glad I got a “good deal” on them! I guess the first buyer should have given them more of a chance.
NB: today added Isoacoustics mini pucks between speakers and stands - I am now in complete awe and listening way too late into th3 night!
@@Laimack The pucks changed the sound?
m m Yes, very clearly! In particular the bass and mid-bass frequencies are a lot tighter and the sound is generally cleaner. Mind you, the speakers were resting on spikes (bottom and top of the stands) but they have rubber underneath them, so that was definitely not ideal (coupling to the stands but not like if screwed - either too much or too little coupling if you know what I mean) and I was going to replace the spikes with sorbotane (rubber) pods. In the end I decided to go for mini pucks (Orea is recommended but way above budget) and I am so glad I did!
I remember setting up a new stereo for my parents some 15 years ago. My mom thought the speakers were a bit harsh and sharp sounding when she heard them first. Played them all day when they were at work and I at school. Gave them a good beating on the volume whenever I could, before they got home. After a couple of days I asked them to sit down and listen again. Wow! Gone was all they complained about. Asked what I changed on the settings? Nothing!, I told them ;-)
My experience: Some speakers it has a huge impact on. Others only minor, but they all have a noticable difference before/after burn in (unless we speak very cheap or shitty bluetooth speakers etc.). Electrical burn in on CD-players, amps, cables etc I don't believe much in as I have never heard a clear enough difference to verify it.
Electrical burn I guess does happen but if everything is new then you'll never hear the differences i guess.
Woofer cone is stiff until used for a while. I hand pumped one after a year's use and it was easy to pump. I then bought another exact same new driver and it was really hard to hand pump. Objective evidence!
Lmao
If you have electrolytics in the signal path, you will absolutely hear a positive difference after some hours of burn in. Ive noticed this with particular metalized film types like the red/yellow polyester wima caps too. The red polypro wima's sound considerably better when new over the red ester WIMA's, but imho, the polyester wima's sound better then the polypro when both are compared after 100 hours of use or so.
With top quality film cap types i havent really noticed a burn in period or significant change through time, that is unless being used for the output filtering on a class D power stage. It really does seem like ALL class D power filters need a solid break in period to perform their best. I've yet to play with a brand new class D amp of any variety/manufacturer/price point where this wasn't the case. Even PS audio takes a significant time/profit hit to give long burn-ins to all their class D filter designs for this very reason. It's so the very large high voltage rated capacitors can form under exposure to the heat and current the signal produces. Forming DOES indeed even apply to quality film types if they're physically large enough or if the voltage rating is fairly close to the intensity of the signal passing though it (1 or both apply to basically all class D filters), at least in my own personal experience.
I have never had a pair of speakers not do exactly just what you are stating. Most get burned in from a weekend to two weeks.
Solder changes will also benefit from some burn in. This has been for around 50 pairs of speakers from $6k to $250k.
I have a play list of a dozen songs, many I played on guitar when I was younger, to compare how they sound. It really does sound different with time. Thanks and keep up the good work. Oh and I'm using a Clio FW but I have only tapped a 10th of its potentual.
I have had many Speakers that didn't change much with break-in, but recently got a pair of Floorstanders that actually opened up after a surprisingly long period of break-in...
My headphones definitely changed in sound after some hours, at first they had a horrible sibilance and that disappeared completely
love anecdotal evidence presented as fact
The commonly held belief is that all aspects of sound can be quantifiably measured. This really is naive because new ways of analyzing and measuring are still to be discovered. They never used to measure transient inter modulation distortion (some still don't) of speakers. I have experienced break in of speakers, but after my last capacitor upgrade I feel that caps may be even more significant in the change heard during break in than drivers.
You are correct. Some caps can take longer and the changes can be more significant.
One of the most profound break ins that I have heard was after recapping my amps; almost unlistenable to amazing, I wasn't expecting anything like that.
Funny thing. I always said these people who think their speakers need burn in are crazy! There is no way! Then, a couple weeks ago I bought some new speakers. Hooked them. UGGGHHHH. Horrible. No bass tinny sounding crap. What a waste of money. Two songs later....hmm....a couple more songs.... exactly what I expected. Great speakers. Who knows how long they will improve for but I am now a firm believer in speaker burn in.
thank you
Most speaker manufacturers run all the drivers in for hundreds of hours, what a load of shit 2 songs changed the sound
@dalechalfont112 well if you are churning out multiple speakers a day in a big factory, the logistics of a room of amps and sinewave generators to burn in every speaker in the day's production becomes cost prohibitive.
I had some older speakers that sat unused for about 10 years. When I set them back up, they were very harsh. I just use the system for listening to music while I work at my desk. Overall, I switched from CDs + reciever to my computer streaming (Spotify) via blue tooth to a cheap Class D mini amp. In the past 2 weeks (a few hours a day) of using this setup, it is starting to get back to sounding good. Harshness is vastly reduced, but I wonder if the BT + cheap amp have become the limiting factor to the sound getting better. Guess I could always dig out the old amp, run some wires, and give it a listen. But then, that equipment also sat for 10 years.
I bought a set of klipsh rb81 bookshelf speakers . they sounded awful at first but after 100hrs or so they really changed .they are now one of my favorite speakers .
I've owned Klipsch Forte III's for 5 years. Probably have thousands of hours on them. Just purchased a second pair as a backup because I dislike the phenolic driver in the Forte IV. Plugged them in to make sure they work before packing them back up and storing them - they sound exactly the same brand spanking new as the ones that are 5 years old.
I agree to all you said. I made a test the last couple of days ago. In my cab I had a fairly unused speaker. I hooked up a sound source and let it run for about 16h. I covered the cab with all I had because of the neighbours. It is a 12 inch speaker and my thoughts were it has bigger components. That means everything is a little stiffer. I choosed dynamic sound at decent volume. What happened it sounds not much better now but a little more midrange. But I won`t let it run 24/7 now. I was just curious about what effect it has. Too many opinions of how, length etc.. I even had a sound room very close that is completely isolated. No reflection at all. The purpose is not for speakers but sound of any components they want to check. It is GE now. I took a noise test gear once of them to test the noise of my bike. Long time ago though. Anyhow, thanks for the facts.
I built some 2 way speakers, used them for a year and took out the 8" driver and hand pumped it fairly easily, before putting the driver back in the box. I ordered another brand new (same) driver (for another set of speakers). When the driver arrived it was so stiff that l would have wrecked the paper cone before it would hand pump. It would obviously take way longer than ten seconds to free up the cone. Iol Obviously they don't make speakers and don't hand pump drivers either.
When I completed my first pair of DIY MTM's I thought I did something wrong lol. They were thin and harsh. However, over time they did sound better and easier to listen to. By six months I was over joyed! I find it funny how opinions on the internet have got to a point where talking about loudspeakers has become a battle of sorts.
Just an observation. I haven't ever heard of anybody saying that after burn/break in, their equipment sounded worse....only better. Not arguing if burn in is real or not, just something that I noticed
I'm not a music guy at all but I do love movies! I have always noticed the break-in change with my mid level receiver/speaker gear. Always!!!
I believe the harshness has more to do with the capacitors in the crossover forming. Has anyone noticed harshness on a full range driver without a crossover?
I have read about some CRAZY burn in times for Magneplanars - the website mentions a "burn in period" but does not specify a particular time window. People talk about 200 to 300 hours on forums but who knows where that originated from.
@Cliff Moore - I find lead guitar solos, or any kind of dynamic rock music for that matter, lacking on Maggies. That's the reason I don't own them because on classical and instrumental and vocalist genres there's nothing better than the mighty Magneplanar. If they ever come out with a Magneplanar that will do prog metal justice I'll make the switch.
I agree about 75 to 100 hrs. But some dealers who sell you a bright speaker says it needs 500 hrs and after that you can't return it anymore! Lol
@Thomas Andersen yeah true dat! Also you can compare dealer demo to new pair. For example when your new speakers arrive if same finish. Ask dealer to set them up or not while you are out of the room listen to your one song you are familiar with. Out of 10 times see if you can identify the new pair and the one which is the demo. I can tell you my new pair of Monitor Audio Gold 100 5g sounded pretty good right out of the box.
@Thomas Andersen I'm not familiar with that brand but like I said you have to do controlled test to be accurate. The only true way is to isolate all variables and used a pair that is broken in compare to new pair. So play new pair for say 70 hrs. If you can identify 10 out of 10 times between the two pairs. And then move onto 160 hrs. But if you can't identify after 70 hrs then the rest is possibly subjective. BTW you can listen for differences as long as you want no pressure but you can't be in room when they cycle between the two set of speakers.
Hello from Canada! Great informative video and thanks for all the hard work and countless hours you put into your videos. I have a pair of Energy Reference Connoisseur 30 (rc-30) speakers. I bought these used for $200.00 CDN off a guy that never used them because he didn't like the sound. He only had about 10-15 hours on them. I have about 120hrs on them and they sound great and keep getting better. Is there any tweaks or changes that can be made to get the most out of these? Thanks again for your videos.
Speakers are electro mechanical systems and all mechanical components needs breaking in. Think of engine pistons and cam shafts, they need to run in for at least 1000 kilometres before you can ramp up the revs and drive at high speed.
Woofer cones and tweeter domes needs flexing before it becomes smoother as new materials are quite stiff at first.
Thanks for the explanation. I can agree because I have done lots of burn in / break in with equipment cables tubes, etc.
Just a few tips; I have found the burn in CDs help greatly, but total playing time is still important. 2. Speakers need the power input to fully break in. 3. Vacuum tubes break in very well with tuner/ radio noise from between channels. 30 min. to an hour is enough for the tubes. Works much faster than a burn in CD. Cables respond well to "cable burners" which you hook your cables to. Be very careful with home made burn in devises. They can be dangerous (not worth it!).
I don't know if it was my ears or my speakers, but the ones I just got a few months ago sound much different than they did at first. 🤷
At first they were a little more tilted on the top end, had a little more sparkle. A little more harsh as Danny said. Now they're a little more smooth, a little more creamy, a little more easy to listen to.
Whichever 3 people disliked this video, please just stay off the channel. This is as good an information piece as you will find on this subject, containing facts from someone who knows his shit.
Hmmm, mechanical, chemical and electrical. One of these, when it comes to burn in, is bull...
Since one personal event i experienced, (still my biggest ever speaker break-in awareness event) i care nothing about what speaker break-in deniers say: In my 1980's stereo days, i bought a pair of 3 way s/h German speakers (Schneider) with newly installed replacement 12 inch woofers, the seller told me "they may need breaking in" & the science behind the notion made sense to me tho i never expected anything like what happened before or after. When i got them home, i put them on my otherwise familiiar stereo system & heard next to no bass. Utterly dissapointed, the next day i heard almost next to no bass & they still sounded awful with a massive defecit below 400'ish Hz.
I wired the speakers out of phase & placed them facing each other with a 6'ish inch gap inbetween for max' sound cancellation, (i only required physical cone- movement) I put an awful new-age type c.d. with very mega-deep synths that droned & modulated on & on ad-nauseum, (it's bass was normally so deep in bass & subsonics that i'd use it as a test-CD for subwoofer setting) I left that on repeat play &
left them playing like that in the workshop for about 5 days behind closed doors. When i put the speakers back to their original playing positions, i was very pleasantly shocked! the speakers had all the bass i could ever wish for, nothing close to what i heard on my first 2 day's listening. I cannot be convinced otherwise that those particular new woofers went through a massive improvement & had a real & deep & more powerful bass compared to the wimpy lack of bass as when i originally heard them when new. Maybe speaker break-in can be more or less noticable depending on surround material's elasticity, shape-memory & design but the difference before & after 7'ish days constant break-in was massive in my case.
I do like to let my new speakers break in before I sit down and listen heavily. It's because I want to be able to write an objective review of what they really sound like. My BIC Venturi DV84's and DV62CLR-S's sounded different before break-in, the tweeters had this crispyness that went away after break-in. The port noise on my JBL Studio 530's seamed to calm down a bit after some break-in time. My new JBL Studio 590 towers seamed to have kind of anemic bass at first, but since they've racked up some hours, the bass does now sound firm and freaking awesome!
Any "burn-in" that happens, mostly happens between your ears. I've experienced this many many times. No change in measurements but I "grow to like" the sound or I don't.
Then would you like to explain the changes that are easily measured? You can see them here:
www.gr-research.com/burnin.htm
www.gr-research.com/myths.htm
Maybe true for your ears. I do my burn in while I’m not home.
The change is distinct. Huge difference in harshness and glare.
Listen for five 3-5 minutes every 24 hours. You will get it.
@@mickywes3733 If such a huge difference appears so quickly, how come the sound doesn't change after that? I understand that everything should "settle in" , when talking about mechanics or electronics but if big differences happen in such a sort span of time, shouldn't it happen all the time? I mean, if burn in actually makes differences that can be heard, then burn in a pair of headphones for let's say 20 hours. Just put them somewhere with a long playlist, crank the volume and don't listen to them. Let's assume something significant happened. When we start to listen, sound may still be "harsh" or whatever and after a while you might grow to like it or not, it changes still even though nothing is happening electronically that should explain this. Did I make myself more clear now?
@@OjStudios no, not clear. Sorry.
However, speakers that sound harsh or glaring or whatever because of design, don’t start to sound better as your ears adjust...they sound worse as ears fatigue.
Speakers that sound harsh at first but burn in well, will be unpleasant and fatiguing at first but become smooth and comfortable as they burn in.
If you can’t hear it then it shouldn’t matter to you, but that doesn’t mean it’s not there.
@@mickywes3733 What you just said didn't make much sense. If something is harsh by design it doesn't burn in but something that burns in well changes.. Right. What makes something burn in well? If something is designed to change drastically in few hours of it's use, why it changes just in the first few hours and not anymore after that period? If this would be the case, burn in would've been done already at the factory to hook the buyer with better sound. What kind of manufacturer wouldn't want to give the best first impression?
Some speaker cones and cabinets are made of wood which does change it properties, because of vibrations the pours open up. Happens in cellos, guitars, violins, a bit in pianos etc. Speaker cabinet is designed not to "sound like anything" kind of. Material and shape of course plays a big part but rigidity is a bigger part. Not thin walls like on wooden instruments.
No technical quantitative information I notice. This is simple, the physics is entirely understood, no need to measure. In particular, if there is a burn in effect, it must be designed into the speaker, so the effect will be absolutely known; the alternative that it is not designed in is unacceptable and suggests the improvement, rather than progressive worsening, in every speaker is just a random bonus. Either burn in is designed into a speaker so every manufacturer could show us the change with time, or we believe it's a happy coincidence that the unconsidered burn in always happens to be a good thing. I know what I think, and as a neuroscientist I will tell you the brain can become accustomed to the most extreme perturbation of the senses.
Speaker burn in makes a huge difference ! Over time you get more separation, staging and detail.
And more bass cos the cones free up. I hand pumped a well used driver and than a new (same) driver and it was way harder to hand pump. Objective evidence!
Heres what I know...The longer you listen to a speaker, the more you get used to the sound. Things that bug you can fade, but it works both ways, some things you really enjoyed start to lose there sparkle. Chasing the dragon. As far as burn in, I can see it making a small difference. I also don't think you should rely on burn in the enjoy a speaker, if you dont like it, and someone tries to tell you to wait for burn in...just find another speaker.
I would think that a broken in speaker would give better low end, since it’s easier to move the cone further with less effort. Guess the damping factor of the amp might affect that, though.
So basically, from the speaker driver's mechanical point of view, the change is to the transient response of the driver suspension, with softening of suspension effectively improving damping ratio.
Guitar stings change dramatically over the course of about ten hours of play. At first they are bright then they soften up to the point were they are almost unbearable to play. They really only last for about 30 hours of play. When you read a new book the pages are hard to hold until they soften. Speakers are most definitely the same way. Duh.
After all this, the question boils down to one simple thing: it stands to reason that after an internal suspension of a speaker starts to move, everything will be different, perhaps softer. What no wonder. I find this very natural, just as in any other physical circumstance we find in our daily lives. Why such a fuss about something we are fed up with in our lives?
I don’t really believe in speaker burn in.
BUT ... recently I got the LS50. Plonked it into my main system and it was okay sounding. Realized the highs weren’t all that smooth. Was not that impressed. Not bad speakers but sounded ok only.
So I put them in the bedroom for casual listening and TV duty.
Now after a couple of months later, I take them to the main system. Yeah ... it sounded better.
I also got the RP 600M earlier on. Stuck it into the main system and it sounded ok. After a very short listening, I decided to burn them in. So placed the speakers facing each other, reversed the polarity for one. After 10 hours or so, I put them back into the main system. It sounded different.
So ... I am starting to believe that there is some effect.
Fat Rat ... it’s not that much. Some expensive pieces were mint used items. People who were cash strapped 😬
Fat Rat ... be a smart shopper! Or maybe it’s my Chinese blood 😂🤣
Fat Rat ... it’s your fault! 😬
Ron, I dont understand the thumbs down? You cant really please everyone.
Great vid. Hope everyone can just agree to disagree.
As Ron said, "They ride their tricycles up to the computer and smash the thumbs down button..." Lol... He's spoken to their parents about this problem.
There are people who want to be the first. If they're the first and only all the better in their minds. Just crazy.
It doesn't matter all interaction with a video counts.
Anything mechanical in nature from engine systems to loudspeakers to more or less degree, It all has a wear in period. Anyone whos purchased a brand new atv or dirt bike from a dealer, or bothered to ask while buying a new car, has likely been informed NOT to push a brand new engine hard until "x amount" of gallons of gas or x amount of miles have been driven. You can genuinely straight up damage the cam's and piston housings in the heads if you push an IC engine too hard too soon. Machines have to wear into their spec'd performance, it doesnt matter what kind of machine it is, and a loudspeaker is a good example of a linear excursion motor rather then centrifugal excursion motor like a DC electromagnetic motor or something. It's still a motor, it still functions hrough mechanical excursion.
While im at it, ill go ahead and mention that capacitor heat forming is a very real process, that we also like to call "burn in" and is a very understood process. Capacitors perform differently once exposed to voltage and a bit of heat and they (especially electrolytics) are designed to form into their spec'd values and fill the microscopic conductor pitting inside the dielectric evenly, and this is why they sound different new. If we were to make brand new electro caps at their rated values, they would burn in and settle outside of spec after forming to their conductor pitting. The ONLY way to form a capacitor is to pass signal through it and generate a small amount f heat for an extended period. This usually isnt done outside absurdly high end audio products before selling because it would be a very time consuming and costly process just to do something an end consumer will do on their own anyway.
It doesn't matter what way you slice it, burn in is real. Go by a brand new copy of ANY product you have owned for a while with moving parts or electrolytic capacitors in it, thats still being made and use it. ANY product, electronic or otherwise, doesnt matter, and tell me it feels and performs the same to use as your worn in product, if you do, you are lying to me. It may not be better, but it will absolutely 100% feel different. There is nothing sold on earth with moving parts, or electrolytic capacitors, that doesnt go through some kind of wearing/burning in process. Doesn't exist.
Hell, most things even without caps and moving parts still wear in too. Even a well used wooden soup spoon feels different to use then a brand new one, and i prefer it 10 fold to a brand new one... Idc what Joe-Gaming-Chair has to say about it. Whether its electronic burn in, or physical break in causing operational parameters to change, or wear and tear causing something to act differently then when it was new, it's not just real, its unavoidable, and it applies to basically every product that exists. If you think your brand new loudspeakers will still sound the same 30 days into using them, you are sorely mistaken. If you think your power amp you bought last summer still sounds the same as new. An a/b with a new unit will show you that you are mistaken in your assumption. You'd probably be glad it doesn't sound new anymore, honestly.
Yup. Breaking in a new pair of DFR-52s right now and when I first plugged them in last night, they were unlistenable for music IMHO. Flat, unclear across the spectrum. Good for TV watching and that's it. I left them with pink noise overnight at a medium volume level (... and my bedroom door closed.. lol) for 8 hours. They were where I would expect them to be this morning. About 50%. I ran them through some test tracks and actually could enjoy and get into some music. But the soundstage is still not really 'there'. The clarity is better, but the complete 'wow' factor is just only just beginning to creep in. Still fun to listen to, but with room for much improvement.
I guess what I'm trying to say is that the burn-in factor is OBVIOUS to anyone who considers themselves an audiophile. I would define a basic audiophile as someone who acknowledges and appreciates 3D soundstage - byond all the other base parameters of FR and voicing. Once you tune into that, you're done like dinner and there is no return. :)
@ NRD/Danny - You can't just run of a bunch of stats and provide zip. Danny you're just talking about measurements without presentation of the data. A great start, but show our work.
The tough things about these tests are (1) how to know the degree to which these measured changes are picked up by the typical ear and brain, (2) controlling for the familiarity effects that make the drivers sound more appealing to the brain over time, and (3) reconciling these studies with other studies, such as those done by Joe N' Tell, that show no changes in performance over time.
in the end, it makes no difference, really. if you buy a pair of speakers and don't like them, just play them more (maybe a lot more), and see if your views change. In the grand scheme of things, 200 hours on speakers that you may keep for 20 years isn't much.
Ron, question. Do you know if powered speakers go through burn in? I happen to hear some Klipsh Speaker 5's that to my ears sounded incredibly the only thing I found lacking was Treble extension though there was Treble it was an exceedingly fast roll off is how I would discribe it. I did find the Mids and the air almost Hallowgraphic the Bass was a tad meaty, but acceptable l'm sure I could find my happy space. The Bass did seem fast, but not lightening so. If it was just as present in my room I'd doubt I'd need a sub. Though I'm also certain it would help to open the already seemingly good Sound Stage. Thanks Regardless.
I left my (Genius generated) new speakers on for two weeks at moderate volume when I left for an extended period. That's the equivalent of about two months of forty hour weeks at work that they played.
Nada. What bothered me initially continued.
Break in is not a panacea. It may work.
I agree the spider in the woofer has to be worked in a bit. It's the most
Rigid when it's new.and gets softer or more brittke with age . Also magnetic flux density changes over time. I have old Alnico speakers that need to be re magnetized again.think of it as an electric motor. There is a break in period. Especially with DC motors more than AC motors .electrical mechanical and chemical fatigue. Caps wear out could get overheated and insulation wears out. Paper rubber plastics all wear out and change with time
Try to walk around in brand new shoes, it is the same thing the speaker need to soften up to work perfectly.
I appreciate your comments . . . it isn't about always being right; however, it is about having the freedom to disgust and debate without personal attack. Unfortunately, the ideology of today has unfortunately become: if you don't agree with me, then you need to be censored and silenced . . . that doesn't work for me as I am not politically correct -- never will be, and have a mind of my own. Please keep posting your videos, for it is ideas that encourage everyone to THINK for themselves and to know what they truly believe. I appreciate your generous spirit and your ethics in business.
Do you have to run the drive ‘hard’ for 80-100 hours or moderate listening levels?
My personal limited experience is that moderate and even quiet, even very quiet works for burn in. BUT, that’s all I have done. I can’t compare it to loud burn in.
Very good job here on discussing the mechanical aspects of frequency burn in and Danny’s test to prove it. Actually quite scientific and even included the comments concerning the water fall test showing this-which does mean a frequency test difference. The “proof” of capacitor burn however had no facts presented. Overall well done though.
Thanks you and Danny for presenting this. Fantastic scientific measurements. I trust Danny for his many years of building speakers. I really liked the 10,20,40,80 analogy. And diminishing returns as time goes on as to break in.
Pretty sure I liked the elac reference better out of the box. Now they sound slightly too relaxed at lower volume.
After "the burn in" period the results should stabilize but after a longer period say a year or so do the test results actually show a decline in performance Danny please test
Great video again. A little off topic but can CV D5's(30 years old) sound less "boomy" by rebuilding the crossovers and adding insulation?
for any woofer, if u just used a 20 hz tone during break in will it speed the process up? or is music the best way?
Any audiophile who utters the words "flat earth" in referring to his critics instantly loses all credibility.
Let's quote GR's own article on break in: "Obviously, as a woofer is played over a given time period the suspension compliance changes. This objective data showing changes in the T/S parameters as the suspension loosens up *** does not prove noted subjective differences in the perceived output, or how a speaker sounds, *** but does prove that there is something more taking place than getting used to the sound."
Their own conclusions, in summary are: Something changes, but the changes are so minor that they make no difference to how a speaker sounds. But of course, they have to lean in heavily on the whole "something more" angle, to justify their profit-preserving break in advice, which in the end is nothing more than a tactic to convince people to keep a product long enough to build sufficient cognitive bias to prevent product returns.
Prove it! Do a live blind comparison of exact same speakers - one out of the box and one 6 months old. Then choose the best and change amp/sources. I see reviews and conclusions on $10k speakers out of the box--Boernicke, GoldenEar, Magnepan. Prove that the sound actually softens over time with fixed variables.
I noticed that the intro pic for this tech talk has a JBL Studio 530... i have a pair and like them a lot. Any thoughts or feedback from your standpoint? Have you listen to them?
Working on that review now!
I have the 590's and love them.. :)
Is this also for guitar speakers?
Car audio guys know this .
Especially in the spl subwoofers you notice them get softer over time .
I'm sure this affects the amplifier and the sound quality because of Q and box port and airspace
Changes as the spider (mostly)
Loosens up and the voice coil winding gets heat cycled
Impedence changes ,
Output stages of amplifier
I can believe theres burn in just like New Shoes get better when you wear them awhile and a New Car engine runs better after a few miles of wearing in, one thing I cant believe is buying super fancy cables for a home stereo just get some good thick lamp cord youre good
Rex Holes, you believe shoe's, and engines, because you have owned them yourself and experienced it for yourself. But have you ever owned a nice set of cables to experience it yourself? If not, then you haven't really experienced it yourself. Which would mean that your opinion on cables mean nothing.
Question: At higher frequencies the diaphragm flexes, wouldn't this flexing change the characteristics of the material over time? Wouldn't that affect the decay?
Nothing wrong with the topic. Nothing wrong with putting forth theories and explanations. But don't denigrate blind tests. The gold standard is what can actually be heard. And to remove the power of suggestion and personal subjectivity, put the speakers behind curtains. That takes some effort. Also, don't do the same thing you complain about from others. They dismiss assertions that speaker burn-in is a significant phenomenon. You dismiss the idea that your ears can get used to something. Equally unacceptable.
if speakers sound better after a good break in why dont the factorys not break them in for us
mnhmm that actually got me thinking.
I wonder if you would have time to do a video explaining the effects of boundary gain with ported floorstanding speakers vs sealed bookshelf?
I bought some expensive floorstanding speakers and have found that the bass is boomy due to the 34hz port frequency. This excites room modes and I now regret my purchase. I feel I should've bought some bookshelf speakers instead that roll off at say, 70hz and let my sub take over from there.
Is this something you would consider covering in a future video perhaps?
Cheers,
Mike.
Have you tried covering the port ?
@@greggcheap6208 Hi Gregg. Yeah, I've inserted some porous material inside to still allow some air to flow but it still causes a huge bass bump. Tried completely sealing it too but I found the bass/midrange driver started to make strange noises so it's clearly not designed with that in mind.
The port it a large rectangular outlet on the bottom rear so isn't a standard reflex port.
I'm currently considering the Harbeth P3ESR as an alternative which will allow me to use my subwoofer high level input to let the sub do all the low end grunt.
@@greggcheap6208 The problem I have is that I live in a typical English home. 3 bedroom semi-detached and my lounge is only 4.6 metre x 5.2 metre with a 2.6 metre ceiling height. Not ideal really. Unlike most American homes where the lounge is huge! 😎
@@mb-electricalservices is it possible to disconnect the bass driver ? I may make them too thin but, sub integration may be better ?
@@greggcheap6208 Hi Gregg. Unfortunately no, it's a two way design so just tweeter and woofer. Look then up: Spendor A7. 👍
Fantastic speakers and sound sublime but need room to breathe which I can't give them. 🙁
Jeez. Of course things break in. Especially mechanical things. Your new car needs to be broken in, your recliner needs to be broken in, your baseball mitt needs to be broken in, your shoes need to be broken in. Anything fresh off the factory floor needs break-in time.
A speaker's natural tendency will be to remain motionless like all inert objects.
My Mrs. will tell you it took a long time to break me in.
Does anyone know if speakers are burned in at the factory and which companies if any do this? I don't understand why if it made improvements they wouldn't just do it there and save us the hassle.
Guess it's the same as with an accoustic guitar, that breaks in over time.
in the early 1980's I had purchase a pair of Advent Maestro 3 way loudspeakers. I powered them with a Proton D1200 amplifier. When I first played them they sounded very good. I had a friend and neighbor over and we listened at pretty high volumes. A few hours in these suddenly began opening up and playing louder. This actually happened very rapidly. My friend and I both listed to it happening at the same time. he and I were both amazed as I don't recall this happening in the past. I too believe in burn in/break in.
I had something similar with some Kef Coda 8. In the first couple of hours I noticed the soundstage get wider, with just a bigger, more immersive sound overall.
My Revel concerta 2 speakers. The woofer took somewhere around 300 hr to calm down. I almost sent them back. One day they just calmed down.
You always can tell the guys who got an F in physics and material science. Or they were the guys who have a good memory and get an a on the test but absolutely understand and know nothing they’re getting an A for. 😂 flat earthers do usually the same guys who became supervisors or managers, Clueless
Good stuff. Exactly what I expected to hear from you. I've experienced the same thing with home built speakers over the years.
question I viewed a youtube video not sure who was possibly 123Toid or Impulse Audio were they did some testing on a driver new vs 40 hours of burn in. There was a decent size difference in the freq vs impedance response measurements after. The flat earthers have a real problem on their hands now lol. Is 40 hours enough and does this vary from model to model of woofer ? It would suck to take acoustic measurement for purpose of cover design just to have it all be way off six months after the build is dome.
Is this website Audioholics?
Yes
I found the article from 2005 titled "Speaker Break In: Fact or Fiction? " .
That Gene dude belittled/slagged off Steve Guttenberg awhile back because he didn't agree, not long ago that same Gene dude did the same at an audio show and lost a sponsor, lol karma is sweet
I thought that might have been Gene from Audioholics because I remember hearing his rant on cables as well as this.
Well some people believe you don't have to break in a car engine either , and yet the manufacture pre programs the cars computer to not give you its full horsepower till after 500 miles !!! HMMMMM I wonder why !?! And if there is no such thing as break in , how do speakers wear out !?! I guess you can't educate people that refuse to learn , but you gave it a solid try !!!!!
Ok if you want to believe that , but the voice coil and magnet 🧲 assembly are moving parts and let’s not forget the spiders etc 🙄 and if there is no friction why do the voice coils get hot and good speakers 🔊 have them vented 😱
If you want a woofer with next to no burn-in time and a ridiculously low FS get one with a foam surround. Of course, it will disintegrate in a few years but hey... Fortunately - foam surrounds were mostly a 70's and 80's fad (thanks for that, JBL)
Foam rot was one epidemic, many such speakers put in the hard rubbish, I used to kick the foam rot woofers in or take em home to blow up, The Realistic Optimus 650s and my dad's first speaker pair (no name cabs with Foster drivers) had been given rubber surround kits to save them from demise
Yes, had some old cheap infinity speakers where you could take the foam surrounds out bij rubbing them. Totally rotten in 10 years..
It's good to have your own quiet office, with a bottle of lotion and a box of tissues.
Funny, but that stuff and the purple reading glasses all belong to my wife.
I remember when I purchased a set of b&w 803N's and my god did they sound horrendously bad for the first 100-200 hours! Burn-in was dramatic as hell. The owners manual said that burn-in was around 10-15 hours. Man was that wrong! I think b&w has since made improvements to eliminate this horrible phase (that never returns) But I have owned all kinds of hi-end audio components that did this, and they were all great products.(once they broke in).
The parts of all NEW mechanical devices need time to "settle in". The manufacturer of your brand new automobile tells you to drive carefully for the first 500 to 1,000 miles. The LAWS of PHYSICS are undeniable.
@MAD GRUMPYMAN You're not telling me something new young MAN I have been studying the LAWS of PHYSICS and listening to music for 70 years.
@MAD GRUMPYMAN Very interesting video showing MBL speaker assembly, unfortunately I will never be able to afford any of their products. I think I can find happiness with my new MAGNEPAN MG.7s.
@MAD GRUMPYMAN Very interesting video showing MBL speaker assembly. Unfortunately i will never be able to afford their products. I will be able to find musical bliss with my new MAGNEPAN MG.7s.
And another thing... if you've gone through NOS tube break-in, well... you realize what 40 and 80hr milestones mean.
Weird… That a mechanical device would have a break-in to get to a “normal state” the slowly wear more over time and uses. Lol
I knew about speaker break-in before I was even exposed to the idea of it. Back in the 80s bought some bookshelf speakers that sounded like crap and almost returned them, but kept them in my system for a few more days. And lo and behold they were magically transformed. Only later upon reading speaker reviews I knew the phenomenon was legit.
It’s also possible something like this is just due to you adjusting to the sound, as well. I think both things happen. When we first listen to speakers we have an idea of what we are looking for and if it comes off differently than what we expect, I think it takes time to really hear everything as it is.
@@Cujobob Didnt you see the vid? what you said was specifically addressed and ruled out with testing and measuring (spectral decay).
@@weeooh1 Of course! I've followed Danny's work on this since he initially wrote that part of his website. It's a complex subject though due to how the ear operates. It's very sensitive in some ranges, very insensitive in others. Proving something is measurable is different from proving something is audible.
If Heavyweights like Dynaudio state burn-in happens and even do it in-house when they design them also I've seen measurements with difference in T/S parameters from diyaudio enthusiast Göran @ audioexcite(although I think he works for a speaker company now) who am I to disagree with them what would be the point of them lying. Would make a few fun videos of Dani to look at the works with commentary of some of the more renowned speaker builders in the diyaudo community(most notably Troels , Goran & Zaph ...i`m sure there are many others but these come to mind)
you're just getting used to hearing a familiar sound over time and that makes you like it more over time. there is no Burn In for any audio equipment at all
“I don’t want to kill anybody today with this factual information”😂
Thanks for the excellent explanation! :) A "hotter" topic would have been burn in of amplifiers - or even worse, burn in of hifi cables... ;)
Amplifiers makes sense due to the electrolytic caps and heat cycles. Cables break in sets the bullshitometer a wailing.
I seem to have bad luck with my speakers.
So far all my speakers got worse in sound over time.
Please consider a kanto yu6 review
Always interesting to hear different opinion's on this topic. I will point out though that there is something to gain from a manufacturer's point of view. It's very convenient to tell a customer who doesn't like the sound of their new speakers to just keep them instead of returning them and they'll sound better over time.
Raidho D1.1 took a considerable amount of time to burn in.
All you need to know. Hexibase channel - *Measuring Woofer Break-In* - ua-cam.com/video/XDL4_TIRTu4/v-deo.html
You're welcome.
Oh so for this discussion measurements matter but for speaker cables they don't? Convenient... Yes, speakers and electronics need burn in but lets be consistent…
I think GR Research has a burn in period...takes a couple of videos to decide if one stick around or split...
I bought a pair of paradigm 800Fs brand new and was disappointed in their sound at first. Compared to the infinity QLS1's I grew up listening to, they were not great.
I was instructed to put on some music, leave the volume up and leave the house. I did that, let them play through some rock, heavy metal and classical repertoire for 10 hours. Did that for 2 days while we were visiting family.
Sounded like completely different speakers when I sat down to listen to them again. I love them now, so happy I got them.
EDIT: it may have been the Denon Pma-800ne that needed the burn in. Couldn't tell you.
Who can win anything with appreciations that reflect only a lack of technical knowledge? Wake up and accept things as they really are. Want to do something positive? Turn on your new speakers, drink a nice bottle of red wine, let the time pass and let nature do what it naturally does. The rest comes with time, as it always has been. Forget the fucking measurements on frequency and if you don't like the result, get another speaker set until you're satisfied.
You mean to tell me the earth is not flat!?!?! 😂😂😂😂😂. Great info man, thanks for the post.
Anyone who knows how speakers work will know there HAS to be wear/break in as a speaker is used.
So, regardless of viewer’s comments, do these readings that he sees in his testing translate to audible improvements that those who don’t have “golden ears status” can hear?
Nobody needs "golden ears" to hear differences in speaker break in, one just needs to know what they're listening for and pay attention.
I did not believe in speaker burn in but now as I bought some high grade new speaker I experience is right now. I was suprized and could not believe it, so I talked to my dealer. He said it is true, there is a burn in. Just to make it clear, there was no talk about burn in before I bought them, so this was not a marketing scam to me. After one month they changed, I have trained ears, being a pro musician all my live.
Really nice video. Thank you. Danny is getting better and better in front of the camera and Ron is getting better and better at pushing as many ads as he possibly can in a single video. Thumbs up anyway.
Actually I have little control over how many ads show up, it’s based on how long the video is.
