Everything you know about HiFi subwoofers is... wrong*. 

Today's topic: something that only comes along once in a while... subwoofers. Just kidding. It comes up all the time in fact. As with many things, much of what you think you know about subwoofers and extending bass in your room is, well, wrong. Let's tune in to Arian's knowledge base of wave propagation and see how he fixed the issue. Proximity Bass Controller by Arian Jansen, episode IV.

re: bass I have this problem. I hear tons of bass from my system when I move out of the listening position. Sit back in the listening position and I immediately hear far less bass (no subs though). Glad to know there's a reason other than I'm crazy!

I have to say, anyone who chooses this kind of title "Everything *you* know is wrong and I'm going to school you" has distain for their audience.

Best I can tell that people are having problems with bass and having it in the next room means your subs (or sub) are not placed correctly in the room that you’re listening in. There are techniques for placement of subs in your listening room. One way Paul from PS Audio says is to place your subwoofer in your listening chair and then walk around the room until you find the loudest spot for bass and then place your subwoofer there. Placement of your subwoofer is critical.

super cool and super confusing so hopefully you will be making a follow up video the most confusing part for me is why he has to personally set it up ? why wouldnt he just sell the electronic device we could just hook up to any extra sub and dial in ourselves with some simple starting point instructions he could even sell zoom time for example for those that need additional help

Ah, yes, this is exactly why I use TBI's Direct Port Modulation subs, as they as propagate bass like no other sub.

There is something important which I find missing in that discussion. People underestimate human brain and hearing sense complexity. Our ears are constantly adopting to what we hear in a way that alows to catch the most important information. The moment we understand what we hear in a sense of recognizing source it rejects all not matching rest. Our ears want to listen for understanding - not only to listen. That is why in open air with windy conditions we do not notice wind. And the same when we talk in reverberated room we do not notice reverberation - in few minutes ears learn that constant repeatable the same harmonics does not matter. So by incearsing level of unwantedet by ears and affecting other material bass we give ears information to equalize. More bass means more cure by brain. That sensation is clear and popular while attending big gigs and perceiving too loud sopranos - we leave tha place and find that we got daf for most important part of listening. Untill we regain normal listening again. First what should be done before installing ANY suwoofer is to learn what is the perfect balance of tones. To be amazed with lowest bass was also my experience. But I never applied subwoofer. It was when I was over 20 and was charmed by lowest range in one .... textile saloon. It was way different lowest tones from my perfect sounding speakers at home. (In fact such subtones I acheved only after 50 yeras of constructing spaekaers). When I lerned what and how I made few mid size speakers charming with as low as 25 Hz. They were only almost exactly perfect with rest as I like . Last week I made another speakers with single wideranges which disappointed me because they would play (by ear) not lower than 40 Hz. Then I compared that pair to before made which transmit from 25 Hz - all with my beloved multiinstrumenatl music ( not jazz with 2 instruments plus contrabass), and many vocals.. Result is no difference except last construction sounds a bit deeper and more impressive. I find that that I can live without repruduction of 20-40 Hz range and save on power and size of speakers. Even more because that range sounds best in my hallway

Very informative, thanks Danny. How does the brain decide that the "flappy wind" is irrelevant / superfluous?

Maybe edit your volume a bit higher? Higher peaks are around -15 dB. A little bit of compression should do it. Excellent video man. Question; where is the proximity woofer placed?

A sub-sat combination is the best way to go or get a Devialet Phantom loudspeaker because you hear the bass on that thing.

So what's the practical lesson here? I get that you don't need a giant sub. But since his product isn't available, what can one do to help their setup?

geez. Now I want a ProsimitySub Bass controller and towards the end we find out they're no longer available? and yes i understand it takes specialised installation. I'd be willing to be trained! :D

Apparently, I’m confused. Does this guy offer a product? Is it an actual sub, or some kind of eq?

What is the difference between this solution and what people call DIRAC or other names? Isn't this solution making the same thing? Am I missing something?

I'm pretty sure you've watched Paul McGowan of PS Audio?

Very interesting! Mr. Pete-------> aging hippie

The reel spinning was triggering my tweak receptors 😵‍💫

100% ✨️✅️

Your example with the wind is not good. It is rather the architecture of the ear which allows us not to hear the wind, not the brain. When you don't want to hear the wind in a microphone, you protect it with material that absorbs the wind. The sound can be compared to a series of bubbles with different pressures that propagate. The problem is that depending on the size of this "bubble" it does not always have time to propagate correctly before encountering an obstacle. It can be completely canceled by obstacles or the sound itself. the problem comes from the room and the poor choice of subwoofer size, not from the brain.

I think he is right. I wish my brain would also delete my tinitus. 😀

This is not really very useful in any practical way and actually the 'guru' contradicts himself more than somewhat. Psychoacoustics (neuroacoustics) can be approached as science or art or sometimes there is a 'golden mean' -- but it is always space specific. Mr Jansen makes this point in a very long-winded way. By 'golden mean' I refer practical sound representation applied to a purpose which Lansing did so much to define in practice when cinemas were the main centers of entertainment for the masses. Filling different sized spaces with sounds faithful to purpose led to several solutions which Lansing refined and, in doing so, left us a sort of 'manual' of sound reproduction. Had he lived longer and been less harassed by corporate bosses of aspects of the cinema industry he might have established, with others on 3 continents, a whole discipline of sound reproduction. Relevant to the long piece by Mr Jansen is the fact that Lansing (Martini) approached very low frequencies in terms of "reinforcement" of what frequencies are perceived by human brains not just through the ears. Harmonics of very high pitched instruments and natural sounds and voices also have low frequencies.

Is not that just a faulty myth? As you say we need to have the number of feets to have 20hz to be "unfold". Makes no sence when they can get lower frequency in car audio than they should be able to "unfold". That audio misconception that we need to have as large space as A single wave length has is so obvious wrong! Another example is in ear headphones.. How many millimeters is it from the face of the driver to the ear drum.. Well approximately 23mm on adults. Let us calculate that a wave length that is fully "unfolded" for 23 mm is 14,913 Hz (~14,9 kHz). So the false "unfold" logic is that with in ear headphones you should then only be able to hear from approximately 15 000 hz and above.. 😂 Everyone can see that it is a myth and just totally wrong. Nobody needs over 17 m long room for to be able to "unfold" a full 20 Hz wavelength.. 😅 Please don't spread that FUD to our audiophile friends. ❤

WTF did i just watch? I heard a 20 min word salad and zero to show for it. So there's a solution, but you can't get the solution? What the? I have a power sound sub with opposing 15" woofers , the sub is too the left along the wall behind my couch and the bass is very good. If your not getting good bass, move the sub. I don't understand why people make this shit do difficult.

Just put a sub in the kitchen 😊

Incredible bass out of a giant subwoofer who make subsonic sound??? Why give the Job to the sub only? I get bass out of my towers, not the subwoofer?

What a bunch of bull shit! If you do not hear the bass at the listening position and you hear it in the kitchen, then put the subwoofer in the kitchen and you will hear it at the listening position.
