    Very well answered, Chris. Thanks for the explanation. I’ve often wondered the same myself, as my speakers supposedly go from 20Hz - 30kHz. All I know is that I love how they sound, and that’s all that really matters.

      What matters is actually how we percieve the speaker sound. Not so much about frequency response. Frequency response don't say anything about how the speaker sounds. Only which frequencies that might be sent out of the speaker.

    I am a drummer. You can take a drum and play it in one room of your house. It will sound a certain way. Take that same drum and play it in a different room? It can sound entirely different. Take it into a hall? Different, again. Speakers are no different.

    I think also the popular use of subwoofers changes this a bit too. Even with larger full size speaker setups it seems like you can roll off at around 100hz and let the subs take the bottom end.

    • @oysteinsoreide4323

      At 100Hz you are entering room modes which has nothing to do with speakers but all to do with room acoustics.

      I had ESS Tower Studio monitors back in the day and the were flat down to 30 Hz, Not much music goes this low although when it does it literally shakes one's internal organs. Not sure if I believe in Subs as I would rather simply but quality speakers that go down down to at least 45 Hz +_-3 DB. Those ESS Towers were expensive to say the least

    I was hoping for Chris's thoughts on the SHAPE of the frequency response curve(s), possibly including off-axis response. From Bruel & Kjaer's research in the 1970's through Toole and Olive's more recent published work, and including Arnie Nudell's in-house work, non-flat curves have been found to be subjectively preferable.

    What I expect loudspeaker manufacturers to show is
    1. PULSE
    2. STEP response
    3. DISTORTION
    1 and 2 in a graph with a timeline of 5 ms. Like mentioned in the video as presented by i.e Stereophile.
    Most speakers suck big time at that point. And a good pulse says much more about how it will sound/perform than a frequency response without information about the smoothing applied.

    After many years of auditioned many different speaker brands i have noticed (more in the bass frequency response) that a lower specified frequency response doesnt always indicate "better bass" as this also depends on your system, listening environment and specific speaker cabinet construction and driver materials used.

      I have what I consider my end-game loudspeakers; aDs 910s. With dual-10.5" bass drivers built into their own enclosures inside the sealed cabinets, the bass is sublime and punchy. Now, I've not seen any actual data other than a couple of people who worked during the time the 910s were developed, and they have said that the 910s, which were originally built as studio mains, had a very linear response and the specs, 28htz-25khtz/93db/4ohms was a conservative estimate and I can attest that without a sub I'm only missing the very lowest impact that any competent 12" sub can bring to the system. I consider myself very fortunate to have an immaculate pair, w/stands practically dropped into my lap. In fact, the seller drove 2+hours/each way to deliver them to my house because he worried about possible damage to the cabinets and the stands. I'm eternally grateful to that very generous man!

    The main thing about speaker specs, (or ANY kind of specs, for any equipment, for that matter), is that you have to look for specs that have a good *reference* to compare to, rather than just an arbitrary, meaningless number, otherwise they really don't mean anything useful...
    For example, a really good, well designed, and properly rated speaker will have a rating that's something similar to the following: Frequency Response from 25Hz to 25KHz +/-3dB @90dB Average SPL @1W (or 2.83V into 8 ohms) /1M Anechoic Response (or "in-room" response)... The point here is that ALL of this stuff has to be referenced and stated in order for a spec. to mean anything significant, (and even then it may not be completely accurate, depending on the manufacturer's measuring equipment and setup, but we won't go into that here, trusting that really good companies try their best to rate their products accurately IF they are publishing this complete list of numbers), so having ALL of that info, and being able to understand what it all means, is really the only way to *pre-judge* a speaker, (pre- to actual listening to see how it sounds to your ears, which is essential regardless of specs.!), and really, in general, with all other things as stated above being equal, the *wider* the frequency response of any given speaker the better, because you want a speaker to be able to reproduce as FULL of the *total* musical range as possible, (which theoretically is between about 1Hz and about 100KHz), but the basic laws of physics place various limits on what is *actually* possible in the real world, that's why it's *very* important to have a good frame of reference to compare stuff with!... And the same thing applies to amplifier specs. also!...
    Just go back and look at how equipment was (more properly) rated back in the 70's and 80's especially, (with all associated & necessary references listed), compared to the overly inflated, often total bullshit ratings of equipment and speakers nowadays, in order for everything to be made cheaper and to lesser quality levels, but still appear at first glance, and to the "untrained eye", to be even "better" than before... In most cases it really *isn't* "better"... In SOME ways electronics *have* gotten better than in the past, with better technologies being available now, etc., but without using proper ratings and *complete* references, the "specs" or numbers you see associated with such new equipment may not actually be any better, you just can't tell without proper, complete numbers available to you...
    Because, for example, a speaker that just simply says it has a "frequency response" of say "20-30Khz" without stating anything else, *doesn't mean shit* , (or actually it does mean SHIT, as in total BULLSHIT! LOL!), (and it may, but most likely will NOT have that actual response), because it doesn't give you ANY references as to how *flat* of a response it is, (the +/-dB spec.), NOR how loud it is on average at a given input power, (the XdB @ 1W/1M, 8 ohms or @2.83V/1M spec.)
    The companies nowadays, especially the cheaper quality, "Made in China" brands, are taking total advantage of the average person not knowing how to read AND understand (proper, true meaning), equipment specs, and so it has become pretty much nothing but a "numbers game" now, where they just throw continually larger, "more impressive looking" numbers out there for you to see when shopping, in order to get the *uninformed masses* to buy their shitty products!...
    So do your homework and study up on what is important and essential to know about a product before buying something! Ask a few knowledgeable experts in the field, learn how to read and understand specs for yourself, and most importantly, find a way to audition equipment and especially speakers for yourself, and with your own ears, to make sure it works well and sounds good to YOU, before buying anything electronic/audio/video related... If buying online, look for a company that preferably allows for in-home trials and has a great return policy and reputation for carrying high quality brands!... Crutchfield comes to mind, but there are many other places to get good stuff online too... Of course it's still better to be able to audition equipment and speakers first at an actual, "brick and mortar" physical store where you can go in and listen to stuff yourself, with your preferred music, but unfortunately that's getting more and more difficult to do nowadays, so cherish the opportunity to experience that whenever and wherever possible, and try to support those businesses when you can so they don't disappear completely in the future! Because if that happens it will make it a "free for all" for all of the "lesser quality" bullshit rated, crappy quality brands to take over the world!... We can't allow that to happen!!
    (And BTW, NO, you can't just rely on the sound from a "UA-cam" video review of any speaker either, because the actual sound from that that actually reaches your ears is *severely and majorly* changed by the uploader's camera/mic, the compression involved in the feed through the internet and definitely UA-cam itself, AND definitely by your relatively crappy sounding computer speakers, headphones, &/or your cellphone or tablet!... Remember, sound is ONLY as good as the *weakest, most compromised link* in the chain, from actual equipment and media to your ears themselves, and the more devices you add into that chain, the more "colored", limited and distorted the sound that you actually hear is, that's why it's essential to audition speakers in person, in the same room as they are, NOT over the internet by watching a video!... But since you are already a person who is watching Paul's videos here on this channel, I will suppose that you already know that much at least!...
    I know this was a long comment, but maybe someone out there got some useful knowledge from it... All I can do is try to help others by offering some of my knowledge and expertise about audio stuff, as these videos on this channel also try to do! :)

    @johannjohann6523 2 роки тому

    So if the frequency response of a particular speaker is NOT necessarily indicative of the speaker's performance then 1) why is it listed? 2) what is the specs one should be focusing on the spec sheet to get an idea of the speaker's performance? I've always tended to think people with their crossover adjustment (LPF) tend to set or have their subwoofers set too low. Loke around 80 Hz. I don't understand this as most bass drums in a drumset are around 100 Hz to 120 Hz but can be up to 140-150 Hz. And maybe on a lucky day can they reach as low as 80 Hz but doubtful unless augmented with samples. So the sub then is not playing the sound of the bass drum when people have their sub set too low. And I would think that is the whole point of a subwoofer. It's the bass drum that gets your foot tapping, and people off their butt and dancing to the music. And regarding the sub, I think it's frequency response would be important. So to have your crossover or LPF setr so it can play the full range the sunwoofer is capable of playing? Like 30 Hz - 250 Hz. Or even 500 Hz. Why set a crossover below the subs capabilities? My sub is designed for 18 Hz - 800 Hz, and sounds fantastic and much better than my old sub that was rated to 250 Hz.

    Thumbed up - already subscribed. Can you try and advise me?
    I'm looking for an answer to this - but taking into consideration that it was the same company (Tannoy), giving specs for 2 of their speakers. One is the Tannoy Reveal 802, which says Freq. Rang is 42 Hz - 43 kHz. Vs their Gold 8, which says it's Frequency range is 54 hz - 20,000 Hz. Granted, the low rolloff and high rolloff are subject to being measured differently by different manufactureres and engineering teams, but it's frustrating when a company releases one product, and then it's followup product uses a different standard - I say that because I can't imagine these speakers have such varying ranges in actuality. Most likely, the team that measured the Gold 8 was just being conservative, whereas the team that did the Tannoy Reveal was giving the absolute measurable range (which is uninfluential even by the most liberal standards) versus energy in the upper band, for example, that may impact the harmonic content in an audible way. Am I making sense?
    Is that likely what happened? And what website should I go to for a true evaluation between these 2 speakers. (I need to replace a Tannoy Reveal 802 (not purely for mixing decisions, but also as a musical instrument amplification in a home composers studio.)

    I like to think of a system as four parts. The source, the electronics, the speakers and then you. Sure I can include the room, but I find that systems can move from time to time and rooms can be tweaked like other parts in the system. Chris I'm sure and as we all know Paul believe you start with the speakers. I just finished building my first pair 3 months ago. The work that goes into making a speaker...Yikes. That's why my next pair will be bought. But saying all that, I have the frequency response I wanted, the dynamics, the size... They fit me. Now, are they awesome and EVERYTHING I was hoping for? No. So I'll continue to work on that, but I know these things so well. So It's kinda a journey as Chris was saying looking and listening for speakers that speak to you.

      Moreover, the websites of JBL, Crown and Rane are very useful. Many amplifier manufacturers like QSC, Crown Lab-Gruppen, Peavey and Electrovoice provide product manuals, that contain block diagrams or even their circuit diagrams (Rane), which are also an enormous help, for a somewhat reverse engineering of real product circuitry analysis.

    This is why I stick to my speakers, which are not perfect, but very musical and have, to me, a foundation that I have endeavored to DIY improve over the years . . . still do. I realize that there may be speakers that would knock my socks off, but I know that they will NEVER be in my price range, so why go there? If I want the true essence of live music -- I can and have gone to live performances. From there I can evaluate my speakers and carefully tweak and experiment to my heart's content; and with the help of research, which is freely at my disposal -- why not? I realize that individuals, who have the equipment and have the education, also have the bigger edge -- but I still have enough knowledge to work with this stuff and not blow-up my amplifiers.
    I think it is inherent in this field, to want to improve and tinker, but let's face it, the majority cannot set up a second mortgage to ever buy this stuff, without making ourselves miserable trying to payback and maintain the rest of our budget.
    I figure that if a speaker gives the owner a basic listening satisfaction, but may be weak in obvious areas, that those areas, if the person is inclined, can be improved over time and still fit within a doable range of the hobby; after all, it is your ears, your life, your budget, etc. which is the criteria -- not other people's opinions, which are not paying the bills, nor have your set of ears. It is time for people to THINK for themselves, rather than develop a herd mentality that defines your thinking and opinions for you, which is basically what is wrong with our country today.

    No matter what your speakers are capable of... the room changes that to the point that a fully untreated room will make your speakers sound -nothing- like what they sound like in a treated room or no room etc. Any change to the acoustics of a room can and likely will alter the sound arriving at your ears. Personally... I am good enough with the acoustics thing that when I don't like the sound from the speakers I change the room acoustic treatment setup and or the speakers setup. I can make huge changes to the bass with a few small changes to the room acoustics setup. Therefore the most important part of your speakers is actually the room.

    In short, it’s complicated. Look at the range of solutions out there. The speaker is a system of transducers set up to simulate sounds that we recognise, in a way that makes sense to us. But look at the range of variables that come under the umbrella of achieving that goal and you find a nest of compromises that serves up a presentation that someone might choose to buy. We want accurate dynamics, intelligibility, imaging and phase coherence. Then we put it with amplification in a room, both of which will change what is possible. In short... a loudspeaker system is the point where the electrical signal does its work on the physical environment, through the collection of compromises it represents. It has to get out of the way of the signal enough for the listener to accept those compromises to listen to what’s left of the signal as if it is the real sound.
    The question is not mad, it just highlights how much work the human brain is prepared to do whilst listening to loudspeaker systems and that technical design and taste are the odd bedfellows in hi fi systems.

      In that fact and the waffle that filled the time there is some useful information. The main point being that the person making the video doesn't really understand the topic being discussed. I will now comment for others and make a few points:
      1) They say the low end of human hearing cuts off at 20Hz. This doesn't mean you can't hear 19,18 or 17Hz. It mostly means that by time you get down to about 10Hz it has to be a lot louder to be heard.
      2) Same story going up from 20KHz but also the number is a bit of a lie. A 10 year old can hear a lot higher than 20KHz. A person who has been to many rock concerts back in the 1960s can't hear 20KHz hardly at all.
      3) People claim that phase shift doesn't matter. They are wrong. I am prepared to explain why but for now just take it as a given.
      4) On the phase vs frequency graph, a phase shift that is proportional to frequency just means a delay in the overall signal and can be ignored for most purposes.
      5) On the phase vs frequency graph a phase shift that goes more than about 45 degrees off the proportional part starts "color" the sound.
      6) On the phase vs frequency graph a phase shift that goes more than about 90 degrees off the proportional part starts is getting into the area where sound at that frequency is going to get noticed.

Any discussion of resonant frequency's that attenuate or enhance the ability of a speaker to be heard or felt outside the 20-20000 hz range belongs to the cult of audiophile craziness.

      @dl6519 4 роки тому +1

      "Distortion" implies that the speaker is producing sound which was not part of the original signal. This is not a significant issue for a good loudspeaker used within its linear range. Frequency response (which in practice includes the in-room reflections) is of far greater audible significance.
      I am familiar with research which showed loudspeaker distortion of around 15% to be undetectable, but small changes in the frequency response were detectable. So focusing on distortion in and of itself is solving the wrong problem.

    Unfortunately , the spec's on a speaker or the manual of a pair of speaker are almost meaningless. Without understanding ohms law at a minimum, Freq response, and a number of other factors , the states soect simply do not add up or really mean anything to the normal human who is not a tech.
    Power handling (in wattage)
    Resistance. (in ohms)
    Are the two main factors to match up to compatible power sources (Amos or Receivers) this is a very simple way to look at it , but the very basic spec's are so as not to mismatch components.

Having gone to plenty of audio shows, stores, and everything else in between, I can't tell you how many times I have been shown all sorts of miraculous specs just to turn around and have the speaker sound like shit.
    Specs are one of those things where it makes complete logical sense, but in the real world where you are dealing with the human element of salesmanship, you are better off just spending the time/money/effort to go listen to the speaker yourself.

    Human hearing range is not limited to 20HZ to 20Khz. That's just the average. There are people that can hear 12 hz and some young people that can hear up to 28,000hz. There's more to how a speaker sounds than Frequency Response. Transient Response, for example is a much better unit of measure and is more important than FR.

    Speakers will sound different with different components and, different sources.
    Look at it like food, take two pigs from the same litter. Two different farmers buy them, and they are raised in vastly different areas, and fed different foods. If bread then slaughtered, the 1st pigs will taste different, and each generation will taste more different than the previous. Along with the pork, the other food and preparation of the pork will change the flavor.
    So, with audio, simply changing 1 component or recording, will change the sound anywhere from a little to a lot. Switching a speaker to the newer model may not be night and day, but will be different.
    As for the upper and lower frequencies, bellow 20 is good for home theater or a car show. Above 20, not really sure.

If that is not the case , your ears are hearing a different song coming from the walls , floor and ceiling than what you hear directly . That is a big problem for your brain as it needs to correct for that and this takes away computational resources that could be otherwise used for reconstructing a truely 3-D soundstage . This is why "constant directivity" loudspeakers sounds so natural and image so well . Nothing to do with an extra db more or less on this or that frequency range .
