Help me understand "the swarm" in the broader audiophile world

I'm still fairly new out here and am curious about this Swarm thing. I've never owned a subwoofer but I find reading about them--placement, room treatments, nodes, the crawl, etc--fascinating. I'm interested in the concept of the Swarm and the DEBRA systems, and I have a very specific question. The few times I've been in high-end, audiophile stores and asked about the concept of the Swarm, I've tended to get some eye-rolling. They're selling single or paired subwoofers that individually often cost more and sometimes much more than a quartet of inexpensive, modest subs. The same thing can be said for many speaker companies that make both speakers and subs; it's not like I see Vandersteen embracing the use of four Sub 3's. 

My question is this: do in fact high-end stores embrace the concept of multiple, inexpensive subs? If not, cynicism aside, why not? Or why doesn't Vandersteen or JL or REL and so on design their own swarm? For those out here who love multiple subs, is it a niche thing? Is it a certain kind of sound that is appealing to certain ears? The true believers proselytize with such zeal that I find it intriguing and even convincing, and yet it's obviously a minority of listeners who do it, even those who have dedicated listening rooms. (I'm talking about the concept of four+ subs, mixed and matched, etc. I know plenty of folks who embrace two subs. And I may be wrong about all my assumptions here--really.)

Now, one favor, respectfully: I understand the concept and don't need to be convinced of why it's great. That's all over literally every post on this forum that mentions the word "sub." I'm really interested in why, as far as I can tell, stores and speaker companies (and maybe most audiophile review sites?) mostly don't go for it--and why, for that matter, many audiophiles don't either (putting aside the obvious reason of room limits). Other than room limitations, why would anyone buy a single JL or REL or Vandy sub when you could spend less and get ... the swarm?

Even Richard Vandersteen believes that multiple subs are better than one or two.
PM ctsooner. He spoke with Mr. V. about this not long ago.
Though I have to say the new Sub 3 with equalization will probably be very close to multiple subwoofers.
I will be ordering them for myself, soon.

and in fact we have with internally geared hubs (the Rohloff being the best of them) and the Pinion gearbox which is mounted in the frame.
No kidding....

Rohloff 14-speed German Speedhub and Pinion 12-speed gearbox.....my Dura Ace have been absolutely reliable but man, those two internal hubs are sweet!

“A swarm would sound better than one or two subs most people do nothave the room or desire to have 4 subwoofer boxes in the room along with a pair of main loud speakers
So the reality is swarms almost never come up based on practicality vs performance”

Bingo! 
In my room, I am more than content with a pair of mid-size REL’s.

This is what’s called a "straw man argument", and is a fallacy. Here’s the definition for anyone not familiar with the term:

"A straw man fallacy occurs when someone takes another person’s argument or point, distorts it or exaggerates it in some kind of extreme way, and then attacks the extreme distortion, as if that is really the claim the first person is making."

Actually Eric is correct in the idea that it does not fix the room. This swarm idea. It overwhelms the problems and buries it under noise, in an area where the human ear is least sensitive. Like Styx said, "you’re fooling yourself if you don’t believe it..."


First, Fix the room.

Fix the room
Fix the room
Fix the room
Fix the room.

Can’t say it enough times.

Fix the room.

Acoustics. But not enough people know how or can supply the material to do so.

I’ve been standing by the side of someone who can fix the room and is many times called in to be the given acoustical and noise control ’cooler’ to the given acoustical company’s ’bouncer’. Where the bouncers, any and all of them (sometimes 4 companies in a row), can’t get the job done. None will guarantee their work. Taras guarantees his work, contractually. Unique, for the most part, in the entire acoustics business.

But he can and invariably does get it done.There is a reason that almost every single time Teo Audio is involved in a hotel room at a show.... it captures ’best of show’.

The stories I could tell you. But he won’t allow me to tell them.

@mitch2 Try taking that Dura Ace on the Tour Divide Mountain Bike Route (google or search on Yourtube) and see how it holds up. If you are careful with it, it can do well, but if you ignore it, it will go away :)

I think this might be the case for now. But as we are seeing, the question is coming up a lot more now than 10 years ago when Duke got his first Golden Ear Award (now there are three).  In terms of practical- the distributed bass array concept is **very** practical in the Audiokinesis embodiment, as the subs are built to be as small as possible (1 foot square by 2 feet) and to be placed inside the room boundary effect, which most subs are not (Duke told me that he often places the speaker on its side with the woofer facing the wall, an inch or two away). This allows them true 20Hz response. In a small room its fairly easy to place them and keep them innocuous. Bass traps are far less effective and a lot harder to hide!


In terms of performance they also shine as they are several times more effective than room treatment for dealing with pesky standing waves which rob you of bass at the listening chair- or give you a bass boom. You get much closer to simply flat response right to 20Hz anywhere in the room. Its highly unlikely that anyone with a single or dual sub system can say that although they may have what they experience as 'satisfying' bass. This means that the main speakers don't have to be very large (practicality- they only need go down to 70Hz or so) or hard to drive (practicality- now you don't need such a big amp) and yet no reason to take a back seat to anyone's system in terms of bandwidth and resolution (performance).
