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?

Hello Erik,

     Rejecting swarming out of hand, without first-hand experiencing it, without maintaining an objective and open mind toward home audio solutions that are based on well understood acoustic and physics principles that have been validated and documented as being highly effective utilizing emprical scientific methods and research? And all because you perceive swarm users enthusiastically extolling its virtues as getting in your grill?
       Based on my recollection of reading your thoughtful, interesting and informative Audiogon threads and posts over many years, that I consistently perceived as commendably openminded  and objective, I consider your responses to swarming and its adherents to be surprisingly out of character. 
     Your reluctance to auditioning and experiencing the numerous benefits of a multi-sub swarm type distributed bass array system in your system and room, ultimately of course, will only be to your own detriment.  I'm just a bit surprised and disappointed that you're not more interested in giving the concept a try, evaluating the results honestly and objectively and sharing your thoughts and always interesting perspective with us all.  I'm certain you'd be pleasantly surprised.

Does the swarm system work equally as well for home theater and music listening? I am 90% HT use and powerful, room shaking, chest pounding bass is what I’m looking for. I currently have a single Seaton Submersive with dual opposed 15” drivers. I have no room treatments, but use EQ via Dirac Live. I am very intrigued with the thought of trying this system.
Mine is used for both. As impressive as it is with music, where it provides truly superb quality bass, its maybe even more impressive with movies because they tend to have a lot more powerful earth-shattering deep bass. Either way its not like you do anything different one for the other. Set it up for one, perfect for the other. 

Its important to keep in mind that while there is a Swarm subwoofer system sold by Audiokinesis, in many cases what people (like me just now) mean is the generic Distributed Bass Array or DBA. That's what I have, a 5 sub DBA. 

Since you already have one sub you are almost exactly where I was 2 years ago when I decided to build my DBA. All you do is add subs! The more the better, and the more powerful the better. But the vast majority of what you get comes more from having multiple subs than from what any of those subs happen to be. The more and more powerful they are simply allows you to run each one at a lower level, giving you greater headroom and extension. You could for example add three Tekton 4-10s and have as much room shaking chest pounding bass as you can handle.
