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?

Good bass is hard, really hard in most rooms. Bass arrays simple make good bass easier. There should be special emphasis on good. They do not magically create great bass, but then it is the rare audiophile with great bass.

There are two types of people, those who don't think low frequency bass is directional and accept that bass arrays must work, and those that think bass is directional and who put subs near their speakers invariably creating combing effects when there is bass leakage to higher frequencies either directly or through distortion that invariable is worse than any issues with directionality from a bass array.

Bass arrays by reducing peaks can even improve decay time and parasitic environmental vibration.


Audiophiles like to talk about fast bass, and then will go into great detail about damping factor, speaker design, woofer diameter and any number of other phantom impacts. Most of the perceived "speed" of bass is room decay. If you want truly fast bass, you have to address your room.  A bass array will help you get there, but can't solve all room issues. Most factory car audio systems have faster bass than high end home systems. Those windows may be reflective, but an automotive interior is filled with a lot of absorptive material by volume not to mention material specifically for sound deadening. Listen to how fast the bass is next time you are in the car.
