Distributed Bass Array configuration


Please, I don't want to debate the merits of the DBA nor of those who espouse it. I am considering adding two more subwoofers to a system that has two already. To those who use a DBA,I am interested in how you have configured them, specifically--
  1. Do you run in mono, or do you split the array to run in stereo?
  2. What is your approach to setting phase (delay) among speakers that may be facing different directions and are different distances from the listener?
Thanks!

It’s pretty funny actually when some worry about things like fuse and wire direction and others shrug off bass as suddenly and totally independent of direction unlike all the rest.
There is no such thing as stereo bass below 80 Hz since it’s a fact that humans cannot determine the originating location of any sound deeper than approximately 80 Hz.

I agree 100% mapman..

It’s not about what we can determine. If you only use the signal from the left of a stereo recording you are leaving out 1/2 of the TOTAL BASS signal. There is a RIGHT side too. There is a left a right and the combination of the TWO.

Mcintosh Preamps
4 outputs; A, B, unswitched and LTE (on the MX120 and C2500)


A - 80hz and down the Rythmik amps (GRs 2 x 12" OB)
B - I run a modified 2496 to split the signal from 80 - 300 hz.
UN switched to the passive XOs for Monitors ONLY (no bass)..
LTE (unused)

When I run just "B" , and turn OFF the monitor amps. LOL There is NO MONO anything... It IS STEREO.. PERIOD.. 80 hz to 300 hz is ALL STEREO.. My ears YOUR ears and anybody else’s ears (as long as they both work pretty good) is gonna hear a stereo signal WITH a center channel to BOOT..

80hz and DOWN has a stereo signal left and right, the TWO are a complete signal with ALL the different BASS tracks laid down. It has NOTHING to do with mono or stereo HEARING. PERIOD!!

JFTR :-)
@mike_in_nc Have you gotten what *you* need from this thread? (MC putting people down and elevating his own genius is, as usual, a freebie.)
It’s nice when people try to help other people. Not so nice when they boast about it and also try to discredit others  in order to claim some sort of monopoly. So the two cancel each other out. See how that works?
