Subwoofer question

I've never seen or heard a swarm. 

I keep yapping about 'stereo pairs' of subs, front facing, no ports, locate adjacent to mains: giving/preserving bass directionality, by virtue of both the fundamentals and overtones of those fundamental notes.

It finally occurred to me: those that use SWARMS must be adding them to systems that already have bass directionality, they are adding more to a system that has more bass than most of us have. i.e. my woofers, 15", 37lb monster magnets, I could add more below what they do if I wanted, SWARM might be best.

Adding a SWARM to a system that does not have decent bass directionality is what does not make sense to me.

in the context of higher end Home Theater multi-channel systems, more that 2 subwoofers is common place. the reason is that more than 2 subwoofers, up to 4, will even out the bass nodes in your room. and each sub is more linear than a single sub. even with only a single low frequency channel. and with movie soundtracks having so much low frequency information it’s a natural fit for that application.

there is lots of information on ways to integrate multiple subwoofers into a system out there to find. the SWARM approach is a very good one.

i have three Funk Audio 18.0 subwoofers in my Home Theater room (on a single LFE channel) and it’s awesome. and i have only level matched them so far, no fine tuning.

forget about deep bass directionality; while it exists really it’s higher frequencies that are mostly giving you directional clues. your deep bass priority should be to even it out as best you can so doubling and such is not overwhelming the music. and 3 or 4 subwoofers around your room will help with that.

"What is the rationale behind facing the subs toward the wall?"

Boundary (driver-wall) reinforcement is increased, thus more bass.

I’ve been singing the praises of the Audio Kinesis Swarm/Debra distributed bass array systems ad nauseam ever since I began using one in my system about 3 yrs ago.
I had no idea that you’re so familiar with the virtues of the Swarm subwoofer system and that you’ve used it at some shows.

AudioKinesis The Swarm Passive Subwoofer System

Again Swarm is a name brand, Swarm, Debra are a type of sub that is small, NOT large and uses the boundaries of the room and facing the wall to increase and also standardize a drop and plop type of listening. It just works. -3db 20hz

DBA is a concept that also encompasses, the AutioKinesis swarm and James Romney’s Debra, Passive subs.

1. They are not powered, they are passive subs.
2. They are smaller cabinets and smaller drivers, and 1-1.5cf cabinets or less.
3. They use the boundaries to reinforce the sub signal.
4. 4 not 44 or 5 or any other number 4 FOUR.
5. DBA (which is an idea) can use 2 large or 15 small ones, they just can’t occupy the same space, they are distributed. LOL
6. Debra is James Romney’s concept bass speaker system. They are HIS speakers not any speakers to comprise HIS Debra, (4 low rider passive subs, cabling and 2 remote power amps. Usually Dayton 1000 watt A/B bass amps.)
James employees a simular but slightly different cabinet construction. YES it make a difference. Not just any old sub will work..

Words Count.. BTW after they Break-in (not burn in) they sound better. I’m a pretty serious bass head. I been looking real hard at 21" active drivers with 2 18" passive radiators in 20 cubic foot 2.25" thick 60" tall cabinets. I made 2 of those columns.

I bet 2 will work just fine in a 800sf shop. It’s DBA, not anything else.

I make a personal product called SAT and Harp. Stack and Test SAT. Harp is an inline speaker cable quick change concept. You can add or subtract up to 20 different alloys to the cable construct quickly, series, parallel or both, Harp!

Someone else might call it jambalaya with red beans and rice. That’s not what it is..
Harp, SAT..

Swarm
Debra
RELs Bass Arrays
OHMs Bass Arrays..

All different names, all DBA

Some of the best statement systems have front facing subs or woofer towers for the exact reason you mention (it works better). I will never sell my Infinity RS1B woofer towers...unless maybe for a set of Genesis woofer towers.
