Distributed Bass Array configuration

@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.

he's not just well informed, but one of the real gentlemen in our field.

Duke is one of those people that I regard as a model human- a gentleman, well versed and an honor to know as a friend.

@atmasphere +1. Never met Duke but that rings true from what I have seen over the years here.  I have learned a lot from him here over the years.   You too!

My XO has a fan also. (XTA DP448) I disabled the fan but left the top cover off so it would cool properly. All with XTA's blessing.
