Anyone know of a sub amp that has a phase control that's adjustable for each output? Or is this going to require a couple of sub control modules between the pre and the amps?

The new Crown series, I think, has adjustable phase control.
Bad room acoustics?

I am not sure what you mean for each output.

I have a Sunfire True Sub and it has Phase control. Now I am using my sub as the cross over between the preamp and the amp. So my IC's go from the pre to the sub and back out to the amp.

The Sunfire also has a Flat/Video Contour switch that when this switch is set to FLAT the frequency response extends dow to 18 HZ. The Video Contour setting will create a low frequency roll off commencing below 30 hz. This will take away the ulta low base.

Hope this helps!

Actually, I want 4 subs total. The room is about 22x24 w/ 18ft ceilings, and there's no way to close it off from the rest of the 2350 sq ft of house, so I'm trying to pressurize an enormous area. I plan to put one ea front, back, and both sides, so I need to be able to do about 90 degree transitions on each to keep everything in phase, as I don't want the AVR trying to do it. I listen to a lot of stuff via the multi-channel in, and that turns off all the phase control stuff.

Since I'm looking at separate amps running to passive subs, I need either an amp that I can control the phase on, or I need a couple of sub control modules.
