Looking forward to the Concert 8/D830 video as i used to own a pair in my main system, had to move to Audio Physic Virgo V to beat them. I recall the Jamos vould have a slight hardness in the mid when used with Musical Fidelity A300CR, or Krell KAV2250 power amps. Cant wait to see what you found, don't keep us waiting too long 😊
The stand mount you have on your right is the well-known D830 from Jamo's high-end Concert series from some 20+ years ago. I have owned a pair for over 18 years now and even if I wanted to change or "upgrade" I simply couldn't. They are simply magical and blow anything in that class and price range (they weren't cheap, though) right out of the water. They also reviewed extremely well, both sonically and technically and everybody who has a pair swears by them to the point they almost reached the mythical status. Thus, you can imagine I am very keen to see your next video on them and how do you find them as a whole. Cheers.
I’ve got the Concert 11 towers and they are the most magical sounding speakers I’ve had in my space. I’ve tried KEF, SVS, Polk LSiM, and Klipsch RP, and nothing even came close to the clarity and the body of the sound coming out of the SEAS excel drivers in that rock solid baffle.
@@MechAdv Agree, those 11s are hard to beat. Modified Sears drivers, sand filled front baffle and double-layer, heavily reinforced cabinet is something you don't often come across these days.
@@MechAdv That's what I am afraid of too. But the thing with speakers has never been 'how they measure' but ALWAYS how they 'sound to our ears'. Danny tends to focus little too much on technical aspects of the speaker's sound reproduction. Granted, steel tube connectors and corroding speaker cable wires are never a good thing but in reality, this is not where the speakers would fail to hit the nail for us, the listeners.
I´ve used the Concert center in my system along with the Concert 8 front speakers for over 20 years. Those are the names when they first came out, now rebranded as the D8 series. Never had any issues with them. The Concert 8´s sound amazing and very musical. Only issue is that the center and the fronts have a very different timber and sound generally. So the whole picture doesn´t come across as a homogenious front if I spelles that correct. I´ve recently upgraded my whole system to M&K Sound 150 and 300 series. Much better. Though the fronts generally don´t sound as musically pleasing as the Jamo Concert 8´s. M&K Sound are more studio monitors and if You feed crap in, You´ll get crap out.
Wow, Danny! I feel your pain on this one. I mean you did what you could, but what POS. Did you consider a proper mid-driver replacement? Unless those bass drivers can be crossed before they beam, this speaker is permanently broken, even with your huge on-axis improvements.
@@doakwolfNegative, the concert series from the late 90s were made with trick cabinets. Real wood veneers and the baffles are a composite mass filled polymer that is seriously inert. I have the towers and they are the most dead knocking cabinets I’ve ever knuckle tested. The center channel was poorly/mildly regarded relative to the stand mounts and the towers, even in 98.
I really like the creative and elegant solutions you came up with to save this speaker and as you have done with many others in the past. A big reason I watch these videos. Question - Would the no-Rez help with the woofer ringing? I know you suggest the poly fill for this, but just curious how the no-Rez works for this sort of thing.
With a stamped steel frame you can stick bits on the basket legs to damp frame ringing but if the woofer is ringing with cone breakup high in its range, then No Rez won’t help.I lined my Linn Kabers, Linn AV 5120 centre in my Home Cinema and 3 pairs of Linn Tukans as the wall mounted Atmos surrounds all with a No Rez like product I found in Switzerland before we moved to Germany a year ago. (Kabers and 5120 are all Active) but the Tukans I developed new crossovers and rebuilt with air core inductors, Polycaps and wound resistors as any decent disciple of Danny would.
I wanted to buy Elac, my wife said "who in right mind spends that much for speakers" Tried Focal - wife said thats too much for speakers. Bowers and Wilkins- thats stupid for a pair of speakers. This is why I am buying used Jamo. 😢
This is anothe case where measuring stuff on paper really doesn't correlate to how the speakers actually sound in a room. Honestly, measurements on paper really are only a basic indication and often have no relevance to how they sound in real life. Sure, changing the cross overs to make them "flat" with no peaks will make the speakers more like a reference and definitely gives an even response, but it also takes away the character of the speakers, and that character and sound of the speaker is why people buy this speaker and not another speaker with a flatter response.
What we see shown isn't how they measure on paper. It is how they measure for real. Also, altering the amplitude in ways as to loose accuracy is not how character is added. That just makes them less accurate.
Reminds me of the Atari 5200 controllers, how they cheeped out so bad that the contacts oxidized inside the controller and it usually wouldn't work anymore when you opened it out the box and used it the first time. Most receivers really don't like 4 ohms even it it's only 2 speakers. Heck, Billy (crappy newer Denon AVR), doesn't like just a pair of 6 ohm speakers.
@@toby9999 Getting really hot, not having cooling fans, AND having a bunch of crap built on top of the heat sink I had to remove. Yeah, built badly, 2018.
The thing is, receivers built in the '70s ran for 40 years. A modern AVR has a very good chance of crapping out within a decade. I've fixed so many of them that had Wish-grade caps and cracked solder joints. Also, yeah, the Atari 5200 was a panic project when they realized the market was moving on from the 2600 and they didn't have a viable alternative other than to make a cheaper version of the 400.
@@bryede Yeah, Billy has so much stuffed in his guts, it's crazy. It's serious a fire hazard. That, combined with no fans and a normie shoving it in a tight spot with no ventilation is recipe for disaster. Also the DSP is really poor, has a yucky sound quality in anything but Direct Mode. My Pioneer VSX-1014TX is vastly superior. I use it as a processor with external amps. It's own amps get nuclear hot.
I wonder if the speaker cables inside the speaker were not corroded/green, if that would make a difference in the measurements, or just in the perceived clarity
Looking forward to your review of the Jamo Concert 8 from 20 odd years ago they have a good reputation using seas drivers and the front baffle is unique using sand in a pregnated resin....I own the bigger brothers Concert 11s. I know the ❌ overs are showing there age .. Danny i will be keen on your take 🙏
These are my speakers here and I'm looking forward to the video myself. After Danny had measured the Concert 8, he said the tweeter output level was so far below the woofer that the the only way he could make it work was to "replace the tweeter". He was just going to send it back without even trying anything. I wasn't a bit happy about that, but after I asked him if there was a replacement tweeter we could find for it, he actually tried to make it work and apparently came up with an answer.
Hello Danny, i have now opened up both my concert 11, concert 8 and my concert center. I do not see any discoloration on my internal cables, and my woofers are made of kevlar is those also made of that on the d8 center ? mine are older so they don't have that name just called "jamo concert center". I have a theory maybe the US market got lesser quality speakers ? maybe the cables couldn't handle getting shipped over seas ? mine are totally clean on every speaker with original cables highly shine copper cable not even close to turning brown ?
Those SEAS drives with the gold coloured phase plug were actually custom modified per Jamo specifications and have been unobtanium for many years. I got the last few drives in existence when I lived in the UK to repair some concert 8's and 11's. I have seen some repaired with the non-Jamo spec SEAS drives so be careful when buying secondhand.
all the brands say they fit modified drivers . usually that consists of not much more than a sticker or a diff tweeter faceplate . i believe the off the shelf part is out of production now anyway and the new comparable one is a different hole size so out of luck if they fail kinda scary i spose
@@jamesccart might be the case with some manufacturers but not so with this SEAS driver. There are other drivers from UK speaker manufacturers too that come to mind where the driver was a custom specification to the off-the-shelf units. Pro-Ac come to mind with their old Super Towers. Two great resources for learning more about such differences are goodhifi in The Netherlands and Gerry at Falcon Acoustics
Yes, C803 were likely the last higher-end speaker stand mounts from Jamo, they were made just after Klipsch acquired the Danish brand and started its long path of cheapening and devaluing Jamo as a brand. What we have these days in shops from Jamo is a joke, Walmart-grade cheap products, a shadow of its former self.
@@matthewtaylor7355 Thanks, but I don't drink, have never been drunk, and never hung over. However, I am still recovering from a muscle tare in my neck. I tore it while training. It is still quite painful.
@@dannyrichie9743"Senior Games" old age is catching up with you, Danny! (Me too, I'm 53, LOL). I hope your neck injury heals up nicely in the short term.
Long ago the Jamo top speaker model Oriel was every hifi magazine's darling. Sure you remember too. I never heard them. Not sure if the magazines checked for gold plated steel binding posts.
Jamo Oriel was great! I went to school with a guy that had these. He used Bryston monoblocks, and they swallowed all of these watts, it was amazing. Yello on these sounded fantastic, I remember. Those were the days… Now Jamo is crap, Blaupunkt also, and other brands sold to China.
Good job getting rid of the 2khz bump, both the woofer as well as the tweeter had a bump there, that's rough! I wonder why they didn't just add a small mid range driver instead of a horned copy of the tweeter above. The mid range could've knocked out the 2khz bump easily and gotten rid of the cancellation around 1khz when off axis. You did all that was possible on this one. Could it be off gassing of the PVC that corroded the wire? PVC contains chloride, which is known to corrode metals. That and braid also acts as a wick sucking in moisture from the environment.
I remember being impressed by Jamo as a kid until I got the C200 center speaker. It sounded hollow and bright. I picked up the Jamo C103s and corresponding center channel when they were only $125 a pair and they have been great for home theater usage though listening fatigue is an issue. But that was their highest end line and I paid almost nothing for them. As I get older, I'm outgrowing my enjoyment of v-shaped sounds, and I think I'll be moving on from Jamo shortly. Not sure with what yet, but something more neutral and easier on the ears.
First off let me just say that I am an admitted speaker design noob, so please see this comment/question in that light. Here is my question: would it not have been an option to keep the woofers in parallel and then just run the one woofer up to the cross-over point, and let the second woofer just run up to the baffle step before dipping it with a baffle-step compensation circuit? That way you would just have one woofer at the cross-over point which would be beneficial for horizontal off-axis.
shit I have bouth of them, the good thing is that I hardly use them anymore (have atleast 10 pair of other speakers to play with) but it would be nice to have them fixed! The E830 was back then an aword winning speaker in Europe and sound really good I think!
As a citizen of Denmark, where Jamo is situated, I'd like to add a few words. Jamo is a low cost brand, generally. And the expectations should be set accordingly. They've built a few more ambitious speakers but are not a brand considered by music lovers. The used ones are hard to sell, even the better ones. I got my hands on a set of two way speakers from them for my 10 y.o. daughter's room. They were quickly gutted. I'd think twice before buying anything from them.
The worst set of expensive speakers i have ever heard were from jamo. They were a pro sound model, buddy bought them for dj gigs. They were full of multiple tweeters and mids, with a x-over just packed with components. Everyone noticed the awful sound.
That is exactly what happened too me when I was like 19… 2 dick heads in a white van driving around a parking lot stopped and asked me if I wanted to buy some speakers cheap…. I said no thanks I got speakers already. Then they chirped me and drove to the next guy…. Had a guy try to sell me sea food from a truck with freezer in the back …. I don’t buy things from dudes in parking lots ,except for maybe some weed when I was young lol
I bought the Jamo 300R in the 80s, believe me, it was a good spieker at the time, it was the most expensive jamo spieker at the time, I still have the sound in my head, but over the years Jamo has no longer made high quality spiekers
I wonder if Jamo deliberately rolled off the upper HF on the centre channel to provide a more midrange forward sound? Afterall it is a centre channel speaker primarily for speech? I just can't believe Jamo would put their name on something soo bad?
Wow that horizontal responce is bad! Could you improve this by making it a 3.5 way and roll off one of the woofers an additional 6dB/oct at say 400Hz? The woofers would need to be paralleled, but given that the centre channel LF cutoff is set above woofer resonance, they could be Lpadded down.
Some people buy these, because it sounds good to them. I used to work at an dedicatedly audio store in the early 2000’s, and most people didn’t take their measuring instruments to buy their speakers. They’d use the same excuse all the time “I forgot my spectrum analyzer at home!”. Morons! So they relied on their own ears, to make a decision. Dumb.
Sir, the use of PVC for anything is problematic. While it does have a low oxygen permeability, we used it in food quality containers for years, it gases out all on it's own over time, worse when heat is applied, and is extremely corrosive to metals as well as organic matter. A pure quality copper wire will be positively destroyed by the vinyl chloride gas out. We had to go to a Beryllium alloyed copper in our process to maintain conductivity, in our case for heat transfer, without destructive corrosion. This would not be practical for wire. But that's surely what was happening on these wires where you witnessed darkening and greening.
Magnetic nuts would have stored energy, so why some cable designer decided to put magnets on the RCA plugs? Wouldn't that be the same? And their higher line, in which they charge $$$$$ would have even more powerful magnet. LOL
Unless there is a difference between the earlier Concert Center and Jamo d8, your measurements don't seem to be as smooth as some I have seen, especially between 3kHz and 10kHz, where I've seen a very slight, smooth upward tilt whereas your measurement shows essentially a downward tilt after 4kHz with an upward tilt from 3kHz to 4kHz. The hump at 2kHz is similar in all measurements I've seen.
When was these speakers manufactured? Fast google didnt find matches for these... Newer must be so bad cos I have owning 10 years and been happy. Sure there is better ones but hitting these down these must be old and newer must be better
But Danny, brass is expensive, gold on the other hand is dirt cheap, if used sparingly. And it's also much more important to deceive the customer than to deliver value .... wait, it's INSIDE???? Yeah, they're just nuts, nuts with a really thin coat of gold.
I think a 2k bump in the center is okay and maybe was a choice for voice focus in the center channel. That’s where the voice lives is 2-4k. But I wouldn’t want that bump in stereo listening speakers.
No, not at all. The heart of the human voice is actually centered in the 300 to 500Hz region. That bump is a coloration that causes brightness and harshness.
seems some of your posters dont live with a piano. middle c is 256 hz so two octaves above it is still only 1024 and that is the highest note sung in opera! so a second order harmonic is all that happens as far as the voice goes. @@dannyrichie9743
It seems with Jamo that their high end stuff was superb and everything else was crap. Sadly. I still have and listen to their Concert VII model which actually won speaker of the year when released.
Danny, it's a center channel....that 3db peak at 2khz (presence band) would have been by design to bring the perception of voices forward/easy to hear.
No, not at all. The human voice is centered in the 300 to 500Hz region. The 2kHz bump is not there by design. It is a response problem with the mid driver.
@@dannyrichie9743 I said you once before. Region from 2-4khz is responsible is where human ears are most sensible to changes in freq. Producers design bump up that freq to brighten the sound and get more analitical and more articulate sound. And it changes how voices sound. I have speakers witch crossover at 1800khz to tweater and upper binding post is connected only to tweater. But you can hear partialy midrange and voice. The same case was when one of my midrange drivers was damaged. I still heard some voices. Very thin but it matters. I had center speaker from line other brand. it sounded different than fronts. It sounded like it has only midrange
The voiced speech of a typical adult male will have a fundamental frequency from 85 to 155 Hz, and that of a typical adult female from 165 to 255 Hz. en.wikipedia.org/wiki/Voice_frequency
@@dannyrichie9743 "Starting with the main frequency range, it is the frequency range of human hearing, which is responsible for the perception of speech. It covers the frequencies from 300 to 3000 Hz."
@@sheerenergy8602 Designing a speaker with a peak at the 2k to 4k range is a very bad idea. That is the range where our ears are sensitive. It is also an area where side wall or ceiling reflections are often strongest. So if anything is is desirable to soften that area. You are not hearing vocals at 1800Hz. You are hearing upper level harmonics in that range.
Subscribed from Australia! This comment is going back to the CDM-1NT's. I bought a pair of these a decade ago and instantly thought they "sounded" worse than my ancient 601/602 series.... They irritated me. And these were not cheap speakers! Sold them and very quickly replaced them with B&W 683's which are 100% Chinese made and assembled and it was like night and day. HUGE improvement. What is B&W doing?????? Great videos. ))))
@@dannyrichie9743Not looking for a perfect representation, just a ballpark to get a rough idea of how much the speaker changed. Or is the difference that subtle?
@@dannyrichie9743 Never mind I found "New Record Day's" video where he compares your modified Klipsch speakers to a stock ones. They sound almost identical, no huge difference. Thanks anyway. Definitely do not post audio of your modifications, it will 100% hurt your sales.
@@roybatty- Nope, they sounded significantly different. That's why we have sold about 300 of those upgrades. The problem with posting a sound clip is that it gets compressed by a UA-cam file and listened to on someone desktop speakers. You can't hear differences that way even if they are huge. I shot a video about sounds clips too: ua-cam.com/video/uYQU25hKRoA/v-deo.htmlsi=VgxJMZmf8fdsPdTM
Erin's audio corner reviewed them a while back and they're rough. A big hump in the mid-bass with a scooped out midrange and a rising treble response. They would be tough to fix.
The other speaker may come later. As for the insides, they sell crossover components and cables, connectors with a belief that they impart a significant effect.
So ÷/-3db from 200-10khz on your graph including the 'massive' 3db peak is awful now? Not shilling etc but that scale isn't particularly wide. Makes it look worse than it is. Also oxidisation does nothing if its only on the outside of a conductor.
Hello Danny. Why are all the speakers sent to you have such bad frequency responses. These manufacturers must have measurement equipment also. Why do people buy these speakers, don't they listen. It seems it's Danny to the rescue for all these speakers. Could you also publish 1/24 octave graphs. Thanks Danny.
Love how everyone in commemts has the "best speakers theyve ever heard. Instead of trash talking another guy for doing something different. JUST DONT WATCH. Better yet wheres your award winning company ? How many speakers have you designed and sold ? Exactly.. zero..
Like in active speakers controlled by preamps with optical out. Light cannot transmit jitter or noise. It doesn't corrode or change its behavior with temperature swings.@@joshua43214
If best typical practices are employed, those corrosion issues are not a problem. I'm guessing it's likely a mis-step Jamo addressed in future releases.
@@FOH3663 This is a $130.00 speaker. The corrosion issue was never addressed, and never will be addressed. Just like the failure to measure the speaker before putting it into production will never be addressed. Jamo makes discount speakers, there is no budget for doing any testing or making any improvements.
Oh Danny... Are you a Joke?! This frequency response is spot on. Especially if you have it tuned for clear voices in movies which is what most center channel speakers would produce 90 % of the time.
Yes the response is a mess, woofers cancel each other, as you try different mic positions, note the dramatic changes in response as driver add and cancel each other. It no joke, not funny its a bad design.
Jamo speakers are only low quality mass market speakers now perhaps they were better in the past but how they can turn out ones as bad as this is beyond belief anybody thinks this would sound good is "mythical"
You cant use a driver as a filer with such a high order crossover step. A filler driver should be as much as it gets FIRST acoustic order crossover. Most People dont have the knowledge and they buy what you say in your videos.. Also you never post the phase response of your new crossover. Maybe cause it's a mess?
Yep Jamo is a joke. You know another joke: Newrecordday Ron blocking me from his comments section because I make jokey and he gets butthert like a beta Texan. Tell Ron to manup Danny! Thanks bro! You are still the bestest and fastest audiophile on the youtubes 🙏🏻🙏🏻🎵🎵🙏🏻🙏🏻
Dang the amount of you who are offended by a graph or evidence of a bad speaker. Jamo has not been any good for years there bright and week in the vocal midrange. Just my opinion
Too bad that "midrange" driver sux so bad. The point of a 3 way center channel is to allow the crossover frequencies to more optimal. I.E. lower between the mid and woofers, and higher between the mid and tweeter. I see no use in a "mid" that only plays down to 1.5kHz. 500Hz or less would have worked out much better. And... what is up with a dome tweeter that won't even come close to 20kHz??? This looks like a dumpster fire.
What I think of how it sounds from the factory is not relevant. The customers that send these in have issues with them and want improvements. So we measure first to see what the issues are. That is a lot faster than setting them up and listening to them to determine the same issues.
MidFi Budget Friendly Loudspeakers! Not for Audiophiles or any discerning music lovers! They’ve always been made at a very low cost point to have a retail price of 6x cost! Example If it cost $100. Using crappy cheesy inductors that cost Pennies, cheap caps, crappy wiring, and ferrous metal binding posts. Manufacturing including their overhead and marketing. Retail will be $600 sold at big box stores who buy it for $300 and market up 100% to $600! sold at Big Box stores! Like now out of business stores like Circuit city, the Good Guys. Both companies out of business! sold at Fry’s? and Best Buy? I’ve seen Jamo at various AV Distributors and low end Electronics Dealers who know absolutely nothing about sound quality. the list goes on and on, GIGO a term used from the computer industry, since the 1970’s. Garbage IN and Garbage OUT If you put bad data in you get bad data out. just like using cheap budgetary parts to get to a build cost to satisfy buyers in a very small budget! Hell why not just buy parts from parts express and their MDF cabinets and parts kits and build your own loudspeakers. They won’t be the same great parts like Danny uses in his kit Loudspeakers. With upgrade options, but your cost will be in the Hundreds instead of $1000’s!
Shame , you definitely where never exposed the high end products that was manufactured in Denmark and got critical exclaim from European audiophiles. But yes, when a low quality manufacturer from the US 😏 took control of the company in 2005 everything went downhill as per usual.
It hasn't "always been" given that they've made some fairly decent speakers. You just see more of the cheaper stuff, because that's the range people spend money on speakers
These were made in Denmark in the late 90s using SEAS drivers. Hence the oxidation on the copper. However I don’t think the center is made the same as the towers or the stand mounts.
@Nonsense623656 Your profile name fits you well it appears. What a nonsensical, unsubstantiated and off the cuff statement from someone who likely only heard of Jamo when they came stateside by acquisition of Klipsch.

No Rez is designed to control cabinet vibrations. Woofer ringing is primarily from cone break up. So, No Rez is not going to help.
I wanted to buy Elac, my wife said "who in right mind spends that much for speakers"

Honestly, measurements on paper really are only a basic indication and often have no relevance to how they sound in real life.
Sure, changing the cross overs to make them "flat" with no peaks will make the speakers more like a reference and definitely gives an even response, but it also takes away the character of the speakers, and that character and sound of the speaker is why people buy this speaker and not another speaker with a flatter response.
What we see shown isn't how they measure on paper. It is how they measure for real. Also, altering the amplitude in ways as to loose accuracy is not how character is added. That just makes them less accurate.
let say high frequencies (above 2k) is not room dependence. it went down like a ski slope
wow 🤦🏻♂️ the response curves speak volumes…. Or not, frequency dependent 😉
Reminds me of the Atari 5200 controllers, how they cheeped out so bad that the contacts oxidized inside the controller and it usually wouldn't work anymore when you opened it out the box and used it the first time. Most receivers really don't like 4 ohms even it it's only 2 speakers. Heck, Billy (crappy newer Denon AVR), doesn't like just a pair of 6 ohm speakers.
No problems with my Denon AVR... at least never noticed them being "crappy".
@@toby9999 Getting really hot, not having cooling fans, AND having a bunch of crap built on top of the heat sink I had to remove. Yeah, built badly, 2018.
The thing is, receivers built in the '70s ran for 40 years. A modern AVR has a very good chance of crapping out within a decade. I've fixed so many of them that had Wish-grade caps and cracked solder joints. Also, yeah, the Atari 5200 was a panic project when they realized the market was moving on from the 2600 and they didn't have a viable alternative other than to make a cheaper version of the 400.
@@bryede Yeah, Billy has so much stuffed in his guts, it's crazy. It's serious a fire hazard. That, combined with no fans and a normie shoving it in a tight spot with no ventilation is recipe for disaster. Also the DSP is really poor, has a yucky sound quality in anything but Direct Mode. My Pioneer VSX-1014TX is vastly superior. I use it as a processor with external amps. It's own amps get nuclear hot.
I wonder if the speaker cables inside the speaker were not corroded/green, if that would make a difference in the measurements, or just in the perceived clarity
Looking forward to your review of the Jamo Concert 8 from 20 odd years ago they have a good reputation using seas drivers and the front baffle is unique using sand in a pregnated resin....I own the bigger brothers Concert 11s. I know the ❌ overs are showing there age .. Danny i will be keen on your take 🙏
These are my speakers here and I'm looking forward to the video myself. After Danny had measured the Concert 8, he said the tweeter output level was so far below the woofer that the the only way he could make it work was to "replace the tweeter". He was just going to send it back without even trying anything. I wasn't a bit happy about that, but after I asked him if there was a replacement tweeter we could find for it, he actually tried to make it work and apparently came up with an answer.
No surprise that Klipsh just bought Jamo. They obviously bought them to copy their surpreme crossover designs.
Hello Danny, i have now opened up both my concert 11, concert 8 and my concert center. I do not see any discoloration on my internal cables, and my woofers are made of kevlar is those also made of that on the d8 center ? mine are older so they don't have that name just called "jamo concert center". I have a theory maybe the US market got lesser quality speakers ? maybe the cables couldn't handle getting shipped over seas ? mine are totally clean on every speaker with original cables highly shine copper cable not even close to turning brown ?
Those SEAS drives with the gold coloured phase plug were actually custom modified per Jamo specifications and have been unobtanium for many years. I got the last few drives in existence when I lived in the UK to repair some concert 8's and 11's. I have seen some repaired with the non-Jamo spec SEAS drives so be careful when buying secondhand.
all the brands say they fit modified drivers . usually that consists of not much more than a sticker or a diff tweeter faceplate . i believe the off the shelf part is out of production now anyway and the new comparable one is a different hole size so out of luck if they fail kinda scary i spose
@@jamesccart might be the case with some manufacturers but not so with this SEAS driver. There are other drivers from UK speaker manufacturers too that come to mind where the driver was a custom specification to the off-the-shelf units. Pro-Ac come to mind with their old Super Towers. Two great resources for learning more about such differences are goodhifi in The Netherlands and Gerry at Falcon Acoustics
Had the c607 and heard the c807. That was far better than the c9 and newer speakers.
Look up the jamo r 909
Open baffle
So true, I own C-803, the successor of the bookshelf D-830 Danny shows above in his video. Phenomenal speakers!
Yes, C803 were likely the last higher-end speaker stand mounts from Jamo, they were made just after Klipsch acquired the Danish brand and started its long path of cheapening and devaluing Jamo as a brand. What we have these days in shops from Jamo is a joke, Walmart-grade cheap products, a shadow of its former self.
Danny looks fed up 😂
He looks hung over or something
@@matthewtaylor7355 Thanks, but I don't drink, have never been drunk, and never hung over. However, I am still recovering from a muscle tare in my neck. I tore it while training. It is still quite painful.

Please do a vid on the bookshelves behind you, I simply can't wait.
from the 80s the coating of the copper may be very reactive with the copper . It not the air but the " insulation " turning the wire green .
That could be, but it was much more green at the ends where the insulation had been cut and no heat shrink was used to seal it.

Long ago the Jamo top speaker model Oriel was every hifi magazine's darling. Sure you remember too. I never heard them. Not sure if the magazines checked for gold plated steel binding posts.
Jamo Oriel was great!
I went to school with a guy that had these.
He used Bryston monoblocks, and they swallowed all of these watts, it was amazing.
Yello on these sounded fantastic, I remember.
Those were the days… Now Jamo is crap, Blaupunkt also, and other brands sold to China.
Good job getting rid of the 2khz bump, both the woofer as well as the tweeter had a bump there, that's rough! I wonder why they didn't just add a small mid range driver instead of a horned copy of the tweeter above. The mid range could've knocked out the 2khz bump easily and gotten rid of the cancellation around 1khz when off axis. You did all that was possible on this one. Could it be off gassing of the PVC that corroded the wire? PVC contains chloride, which is known to corrode metals. That and braid also acts as a wick sucking in moisture from the environment.
…a little bit melodramatic….
Jamo must be the king of deception.
I remember being impressed by Jamo as a kid until I got the C200 center speaker. It sounded hollow and bright. I picked up the Jamo C103s and corresponding center channel when they were only $125 a pair and they have been great for home theater usage though listening fatigue is an issue. But that was their highest end line and I paid almost nothing for them. As I get older, I'm outgrowing my enjoyment of v-shaped sounds, and I think I'll be moving on from Jamo shortly. Not sure with what yet, but something more neutral and easier on the ears.
First off let me just say that I am an admitted speaker design noob, so please see this comment/question in that light. Here is my question: would it not have been an option to keep the woofers in parallel and then just run the one woofer up to the cross-over point, and let the second woofer just run up to the baffle step before dipping it with a baffle-step compensation circuit? That way you would just have one woofer at the cross-over point which would be beneficial for horizontal off-axis.
No, that would have caused an asymmetrical lobbing pattern.
@@dannyrichie9743, thank you very much. That is one of the reasons I love this channel. I learn all the time. Thanks again. 👍🙂
shit I have bouth of them, the good thing is that I hardly use them anymore (have atleast 10 pair of other speakers to play with) but it would be nice to have them fixed! The E830 was back then an aword winning speaker in Europe and sound really good I think!
As a citizen of Denmark, where Jamo is situated, I'd like to add a few words.
Jamo is a low cost brand, generally. And the expectations should be set accordingly. They've built a few more ambitious speakers but are not a brand considered by music lovers. The used ones are hard to sell, even the better ones.
I got my hands on a set of two way speakers from them for my 10 y.o. daughter's room. They were quickly gutted.
I'd think twice before buying anything from them.
The worst set of expensive speakers i have ever heard were from jamo. They were a pro sound model, buddy bought them for dj gigs. They were full of multiple tweeters and mids, with a x-over just packed with components. Everyone noticed the awful sound.
Jam-o and - jam. It. Up. Yours 😂😅😊
That is exactly what happened too me when I was like 19… 2 dick heads in a white van driving around a parking lot stopped and asked me if I wanted to buy some speakers cheap…. I said no thanks I got speakers already. Then they chirped me and drove to the next guy….
Had a guy try to sell me sea food from a truck with freezer in the back …. I don’t buy things from dudes in parking lots ,except for maybe some weed when I was young lol
I bought the Jamo 300R in the 80s, believe me, it was a good spieker at the time, it was the most expensive jamo spieker at the time, I still have the sound in my head, but over the years Jamo has no longer made high quality spiekers
I wonder if Jamo deliberately rolled off the upper HF on the centre channel to provide a more midrange forward sound? Afterall it is a centre channel speaker primarily for speech? I just can't believe Jamo would put their name on something soo bad?
Is there any speaker that is up to your standard?
Monoprice Monolith THX line was well reviewed by him.
😂
Pretty sure he's mentioned some. But remember, these speakers are sent in because they're not great.
Wow that horizontal responce is bad! Could you improve this by making it a 3.5 way and roll off one of the woofers an additional 6dB/oct at say 400Hz? The woofers would need to be paralleled, but given that the centre channel LF cutoff is set above woofer resonance, they could be Lpadded down.
That would cause lobbing in the horizontal plane.
Some people buy these, because it sounds good to them. I used to work at an dedicatedly audio store in the early 2000’s, and most people didn’t take their measuring instruments to buy their speakers. They’d use the same excuse all the time “I forgot my spectrum analyzer at home!”. Morons!
So they relied on their own ears, to make a decision. Dumb.
Sir, the use of PVC for anything is problematic. While it does have a low oxygen permeability, we used it in food quality containers for years, it gases out all on it's own over time, worse when heat is applied, and is extremely corrosive to metals as well as organic matter. A pure quality copper wire will be positively destroyed by the vinyl chloride gas out. We had to go to a Beryllium alloyed copper in our process to maintain conductivity, in our case for heat transfer, without destructive corrosion. This would not be practical for wire. But that's surely what was happening on these wires where you witnessed darkening and greening.
Magnetic nuts would have stored energy, so why some cable designer decided to put magnets on the RCA plugs? Wouldn't that be the same? And their higher line, in which they charge $$$$$ would have even more powerful magnet. LOL
Unless there is a difference between the earlier Concert Center and Jamo d8, your measurements don't seem to be as smooth as some I have seen, especially between 3kHz and 10kHz, where I've seen a very slight, smooth upward tilt whereas your measurement shows essentially a downward tilt after 4kHz with an upward tilt from 3kHz to 4kHz. The hump at 2kHz is similar in all measurements I've seen.
When was these speakers manufactured? Fast google didnt find matches for these... Newer must be so bad cos I have owning 10 years and been happy. Sure there is better ones but hitting these down these must be old and newer must be better
Late 90s. The towers and standmounts were built using FAR more expensive SEAS Excel drivers. The center was pretty mildly regarded from this set.
Won't vocals be worse/lower now?
But Danny, brass is expensive, gold on the other hand is dirt cheap, if used sparingly. And it's also much more important to deceive the customer than to deliver value .... wait, it's INSIDE???? Yeah, they're just nuts, nuts with a really thin coat of gold.
I think a 2k bump in the center is okay and maybe was a choice for voice focus in the center channel. That’s where the voice lives is 2-4k. But I wouldn’t want that bump in stereo listening speakers.
No, not at all. The heart of the human voice is actually centered in the 300 to 500Hz region. That bump is a coloration that causes brightness and harshness.
seems some of your posters dont live with a piano. middle c is 256 hz so two octaves above it is still only 1024 and that is the highest note sung in opera! so a second order harmonic is all that happens as far as the voice goes. @@dannyrichie9743
He said it correctly
"Lets just throw up"
Based on what my ears tell me, there is no such as a flat center channel on all listening angles.
What does measure well?
Se the video right before this one.
Audiophiles sure do complain a lot
Why not totally replace the tweeter on the center channel with something like the little VIFA XT model for $25 ?
By the time you start swapping out drivers and having to cut new front baffles then you might as well start over.
It seems with Jamo that their high end stuff was superb and everything else was crap. Sadly. I still have and listen to their Concert VII model which actually won speaker of the year when released.
Danny, it's a center channel....that 3db peak at 2khz (presence band) would have been by design to bring the perception of voices forward/easy to hear.
No, not at all. The human voice is centered in the 300 to 500Hz region. The 2kHz bump is not there by design. It is a response problem with the mid driver.
@@dannyrichie9743 I said you once before. Region from 2-4khz is responsible is where human ears are most sensible to changes in freq. Producers design bump up that freq to brighten the sound and get more analitical and more articulate sound. And it changes how voices sound.
I have speakers witch crossover at 1800khz to tweater and upper binding post is connected only to tweater. But you can hear partialy midrange and voice. The same case was when one of my midrange drivers was damaged. I still heard some voices. Very thin but it matters.
I had center speaker from line other brand. it sounded different than fronts. It sounded like it has only midrange
The voiced speech of a typical adult male will have a fundamental frequency from 85 to 155 Hz, and that of a typical adult female from 165 to 255 Hz. en.wikipedia.org/wiki/Voice_frequency
@@dannyrichie9743 "Starting with the main frequency range, it is the frequency range of human hearing, which is responsible for the perception of speech. It covers the frequencies from 300 to 3000 Hz."
@@sheerenergy8602 Designing a speaker with a peak at the 2k to 4k range is a very bad idea. That is the range where our ears are sensitive. It is also an area where side wall or ceiling reflections are often strongest. So if anything is is desirable to soften that area.
You are not hearing vocals at 1800Hz. You are hearing upper level harmonics in that range.
Jamo \ klipsch?
I suspect that the Hi-Def wire is drawn from recycled copper pipes and electric motor & transformer windings in China
Subscribed from Australia! This comment is going back to the CDM-1NT's. I bought a pair of these a decade ago and instantly thought they "sounded" worse than my ancient 601/602 series.... They irritated me. And these were not cheap speakers! Sold them and very quickly replaced them with B&W 683's which are 100% Chinese made and assembled and it was like night and day. HUGE improvement. What is B&W doing?????? Great videos. ))))
Let's hear it. Play a before and after the mods.
Doing that accurately is not that easy, and I am not going to show the differences in a compressed UA-cam file.
@@dannyrichie9743Not looking for a perfect representation, just a ballpark to get a rough idea of how much the speaker changed. Or is the difference that subtle?
@@roybatty- If the difference was only subtle I wouldn't even release the upgrade.
@@dannyrichie9743 Never mind I found "New Record Day's" video where he compares your modified Klipsch speakers to a stock ones. They sound almost identical, no huge difference. Thanks anyway. Definitely do not post audio of your modifications, it will 100% hurt your sales.
@@roybatty- Nope, they sounded significantly different. That's why we have sold about 300 of those upgrades. The problem with posting a sound clip is that it gets compressed by a UA-cam file and listened to on someone desktop speakers. You can't hear differences that way even if they are huge. I shot a video about sounds clips too: ua-cam.com/video/uYQU25hKRoA/v-deo.htmlsi=VgxJMZmf8fdsPdTM
Judging by the title, Danny was impressed?😀
Why has no one sent you a Jamo s803 yet? It's easily the prettiest budget speakers on the market.
Erin's audio corner reviewed them a while back and they're rough. A big hump in the mid-bass with a scooped out midrange and a rising treble response. They would be tough to fix.
Jamo don't design, they throw darts at schematic and roll with it! Might have worked once maybe?
my money says that he doesnt do a follow up on the d830
I guess you didn't do anything with the side speakers, analyses, drivers etc? Also, you said the inside is crap but didn't say why?
The other speaker may come later.
As for the insides, they sell crossover components and cables, connectors with a belief that they impart a significant effect.
OK. Thanks! I was under the impression that you didn't like the inside construction of the box.
So ÷/-3db from 200-10khz on your graph including the 'massive' 3db peak is awful now?
Not shilling etc but that scale isn't particularly wide. Makes it look worse than it is.
Also oxidisation does nothing if its only on the outside of a conductor.
D, I have for my front 3, affordable Wavecrest HVL-1's. Could not be happier.
Can you please show your viewers how to read the graphs you show? Many of us would like to be on the same page as you. Thanks Danny

Hello Danny. Why are all the speakers sent to you have such bad frequency responses. These manufacturers must have measurement equipment also. Why do people buy these speakers, don't they listen. It seems it's Danny to the rescue for all these speakers. Could you also publish 1/24 octave graphs. Thanks Danny.
I keep thinking the speaker must be damaged 😢
We wondered the same, but we found measurements made by others that looked exactly the same.
@dannyrichie9743 Every brand has some duff designs I guess! P.S. Nice rework on the xover. Good call to series the woofers to match the tweeter level.
Love how everyone in commemts has the "best speakers theyve ever heard. Instead of trash talking another guy for doing something different. JUST DONT WATCH. Better yet wheres your award winning company ? How many speakers have you designed and sold ? Exactly.. zero..
With all these crystalline conductor problems wouldn't audio fidelity be better served using more Toslink connections?
how would you put toslink in a speaker?
Like in active speakers controlled by preamps with optical out. Light cannot transmit jitter or noise. It doesn't corrode or change its behavior with temperature swings.@@joshua43214
If best typical practices are employed, those corrosion issues are not a problem.
I'm guessing it's likely a mis-step Jamo addressed in future releases.
@@FOH3663 it’s a 25 year old speaker, you don’t know if it lived his life near the beach or in south east Asia or something.
@@FOH3663 This is a $130.00 speaker. The corrosion issue was never addressed, and never will be addressed. Just like the failure to measure the speaker before putting it into production will never be addressed.
Jamo makes discount speakers, there is no budget for doing any testing or making any improvements.
Oh Danny... Are you a Joke?!
This frequency response is spot on. Especially if you have it tuned for clear voices in movies which is what most center channel speakers would produce 90 % of the time.
:-) Yeah, it's perfect. 😉
Bro my name is kavin jamo hello ?
Yes the response is a mess, woofers cancel each other, as you try different mic positions, note the dramatic changes in response as driver add and cancel each other. It no joke, not funny its a bad design.
Gold-plated steel is not worth its weight in gold.
Ha ha lol😂
Jamo speakers are only low quality mass market speakers now perhaps they were better in the past but how they can turn out ones as bad as this is beyond belief anybody thinks this would sound good is "mythical"
Jamo? Might want to rethinko that.
Oh Danny oh Danny. Concert 8's outplay 95% of bookshelfs ever made under $4k. Bottom line. End of controversy 😮
Aaa I am proud of been danish, so much good hifi is made here...why look at those speakers? wast of time!
We look at whatever customers send to us.
You cant use a driver as a filer with such a high order crossover step.
A filler driver should be as much as it gets FIRST acoustic order crossover. Most People dont have the knowledge and they buy what you say in your videos..
Also you never post the phase response of your new crossover. Maybe cause it's a mess?
Yep Jamo is a joke.
You know another joke: Newrecordday Ron blocking me from his comments section because I make jokey and he gets butthert like a beta Texan.

Dang the amount of you who are offended by a graph or evidence of a bad speaker. Jamo has not been any good for years there bright and week in the vocal midrange. Just my opinion
Just facts , no bullshit. Great job Danny.
An crap on the inside.
Just why.
How can we make chezzezy if the milk goes bad beforehand.
Ride Easy
Too bad that "midrange" driver sux so bad. The point of a 3 way center channel is to allow the crossover frequencies to more optimal. I.E. lower between the mid and woofers, and higher between the mid and tweeter. I see no use in a "mid" that only plays down to 1.5kHz. 500Hz or less would have worked out much better. And... what is up with a dome tweeter that won't even come close to 20kHz??? This looks like a dumpster fire.
Oh dear Jamo 😢 . shocking!
Do you ever listen to a speaker first? Or just jump right into measurements.
What I think of how it sounds from the factory is not relevant. The customers that send these in have issues with them and want improvements. So we measure first to see what the issues are. That is a lot faster than setting them up and listening to them to determine the same issues.
@@dannyrichie9743 ok cool, I was just curious as to your process. thanks

Paraphrasing Michael McDonald: "Jamo be there....". Jamo never impressed me at any price.
Tell the truth. You bough these from a guy driver a white van.
MidFi Budget Friendly Loudspeakers! Not for Audiophiles or any discerning music lovers! They’ve always been made at a very low cost point to have a retail price of 6x cost! Example If it cost $100. Using crappy cheesy inductors that cost Pennies, cheap caps, crappy wiring, and ferrous metal binding posts. Manufacturing including their overhead and marketing. Retail will be $600 sold at big box stores who buy it for $300 and market up 100% to $600! sold at Big Box stores! Like now out of business stores like Circuit city, the Good Guys. Both companies out of business! sold at Fry’s? and Best Buy? I’ve seen Jamo at various AV Distributors and low end Electronics Dealers who know absolutely nothing about sound quality. the list goes on and on,
GIGO a term used from the computer industry, since the 1970’s. Garbage IN and Garbage OUT If you put bad data in you get bad data out. just like using cheap budgetary parts to get to a build cost to satisfy buyers in a very small budget!
Hell why not just buy parts from parts express and their MDF cabinets and parts kits and build your own loudspeakers. They won’t be the same great parts like Danny uses in his kit Loudspeakers. With upgrade options, but your cost will be in the Hundreds instead of $1000’s!
Shame , you definitely where never exposed the high end products that was manufactured in Denmark and got critical exclaim from European audiophiles. But yes, when a low quality manufacturer from the US 😏 took control of the company in 2005 everything went downhill as per usual.
It hasn't "always been" given that they've made some fairly decent speakers.
You just see more of the cheaper stuff, because that's the range people spend money on speakers
These were made in Denmark in the late 90s using SEAS drivers. Hence the oxidation on the copper. However I don’t think the center is made the same as the towers or the stand mounts.
@Nonsense623656 Your profile name fits you well it appears. What a nonsensical, unsubstantiated and off the cuff statement from someone who likely only heard of Jamo when they came stateside by acquisition of Klipsch. Dig deeper, do your research well into Jamo's Danish past, who knows you might even learn something before beetling your tongue in public next time.
