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!

@noble101--  I am acquainted with Duke through other channels and have had some information from him since posting. I do agree about his extensive knowledge on this topic, through setting up systems in many situations, as well as design work. I have observed Duke help users like me, who are unlikely to be buying a Swarm from him, and I've concluded that he's not just well informed, but one of the real gentlemen in our field.

I also like hearing peoples' experiences in their own systems; yet, it is not always as possible to generalize from them as it is from those of someone who's done the same thing in varied circumstances.
My name has come up a few times in this thread.  I don't really see how to participate without either taking a side in an emotionally-charged "us versus them" thing that I want no part of, or turning into a self-appointed thread nanny.  Until I figure that out, I'll just tip my virtual hat to @mike_in_nc for taking the high road.

Great Mike, I recommend the Anthem all the time along with the Trinnov Amethyst and the DEQX units. I need to look into the MiniDSP units as they are even less expensive and seem capable. 

I have not heard your speakers but I am a big ESL fan. They are point source. I would add two more JL subs in the front corners. 80 Hz is fine, 24 to 48 dB/oct. 

The TacT has very proprietary circuitry. You really can not do anything with it. Shame what happened to it. I plan on getting the Trinnov but I won't like losing the dynamic loudness programming. 

If you can create separate target curves for the channels work on EQing the speakers so their frequency response matches perfectly 100 Hz to 10 kHz. You will like what happens to your imaging. You have to look at it with your measurement system. The room control programming will not do this. It is well worth the work.
