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?

The idea that only swarms can sound good, or are the ideal fix for any possible ailment your system has is just not supported by evidence.
atmasphere
I do not believe anyone here is making that claim ...
But that is exactly the claim that some have made:
millercarbon
Surely no one with the room, who takes the time to compare, would ever choose anything else. No one has. No one ever will. The difference is so night and day that Duke had one customer with a $30k subwoofer budget decide to buy the Swarm. Not even a $30k sub can match a $3k Swarm.
So there’s your answer ... Because since we all know no one or two subs can ever touch a DBA, then not only do the high-end dealers make money selling you the one sub that can’t work, they get to sell you another ... sinnce you already know DBA works, and yet is not widely adopted, then you know how good they are at selling audiophiles on stories ... Why would anyone buy a sub? They don’t. They buy a story
And here’s another:

Proving the superiority of a multi subwoofer setup is easy ... the ultimate subwoofer system requires 4 large subwoofers with at least 2000 watts of power each and room control.

One SW12 provides satisfying high quality mono bass. Two SW12's produce more realistic stereo bass, higher levels, and better smoothness. Three SW12's add front / rear information and truly envelope the listener in bass.

@mitch2,
Your above quote from Aerial’s Michael Kelly is very similar to a multiple sub white paper excerpt here:

Subwoofer setup after Earl Geddes (GedLee LLC)

The multisub setup described on this page has two big advantages over other methods: only three subs are needed and you don't need to put the subwoofers at specified locations. Nonetheless there are some basic rules that have proven to yield best results:

Put one sub in a corner close to the mains. The second sub is a lot more flexible as to its location, but it should not be in a corner. Side wall or back wall, near the midpoint is a good idea. Put the third sub wherever you can that is not too close to the other two. It's a good idea to get one of them off of the floor.

Subwoofer requirements

Because we are using 3 subwoofers, they do not need to be as powerful as a single subwoofer. Any decent active subwoofer (ported or closed design) with a 10" or bigger driver will do. It should have controls for

  • level (continuously variable)
  • low pass frequency (continuously variable)
  • phase (switchable or continuously variable)
  • parametric equalizer (optional)

I’m an advocate of using the Swarm because it fixes bass issues by breaking up standing waves in the room, something that can’t be done easily with both room treatment and bass management combined.
You forget Active acoustical device controls...

People dont realize that bass dont exist in his bass world.... All frequencies are linked together in the acoustical space...

The easiest low cost way to improve bass is to improve the acoustical settings controls of the room not only passively but actively...

The idea to improve bass with woofers BEFORE improving the room acoustic baffle me.... Sorry....

What do we want a better sound musically or a bigger bass?

I dont doubt that the swarm is a good idea, read me for what i said....

It probably seems highly counter-intuitive that a SMALLER room would benefit the most from having a LOT of subs, but the explanation is pretty simple:

Smaller rooms start out worse, and therefore have more room for improvement.
This affirmation is comical in a way....If you are a shorter man you will benefit the most from a larger suit!

The truth is acoustical treatment and active controls change a room, bass included....The suit fit the individual so to speak....

I am sure that Swarm is a good idea, i repeat, but for most people not a good one at all, because impractical, and costly, and changing the acoustic dont begin with the bass obsession....

I mute myself now.....

So if you have three subs that are all powered, what is the best way to integrate these into the chain? Especially if I wanted to connect them all at speaker level. Can these be piggybacked somehow so you don't need individual speaker cables from each one running to the main power amp?
Perchance, did anyone see this important question?
