Distributed Bass Array configuration

Understandable.   I feel the same way quite often. 

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. 

millercarbon I am afraid you are dead wrong in asserting time and phase do not matter. You are saying this because you have no control over them. If you did you would be piping a different story. Out of phase and time destroys bass transients like kick drums and thumbing bass guitar strings. If you had the ability to control phase and time you would know otherwise. 

@mijostyn - What ruled the Amethyst out for me was that it has a fan, which a couple of reviewers have reported hearing. In my very quiet room (~26 dBA SPL), any fan noise would be obtrusive. Since Trinnov is reputed to have the very best RCS, I wrote to them and asked if they might release a fanless version. They said no.

"All-Pass phase controls operate at only a single frequency with varying degrees of shift across the passband."

Yes, that’s because they are really delay controls, and a given delay is equivalent to different fractions of a wavelength (phase) at different frequencies. But as far as I can see, delay is what’s needed to align speakers that are different distances from the listener (and might have different latencies).

At least, that's my understanding of the situation.
