Dayton Audio IB385-8 15" Infinite Baffle Subwoofer
All external variables aside, if this was put into a simple, strong, well-damped 19.39 cu ft (PE stated spec) bass reflex enclosure tuned to the f3 15 hz resonance, what would be your expected results in open space at 230watts?
This is more of an IB driver but that should do fine in a open room,. The ported alignment will bring out the bottom end a little more than using it in an Infinite baffle setup.

If this was put into a simple strong well damped 19.66 cu ft (PE stated spec) bass reflex enclosure tuned to f3 20 hz resonance, what would be your expected results?
Are there any issues with "remoting" the plate amp, placing it in the media room below, and running the speaker wires to the two IB385-8 15s placed in the infinite baffle setup in the ceiling? That would be much easier to "tune" it.
There is nothing wrong with wiring a setup like this.

On the IB 385-8 15, if I bought two, mounted them opposite in an 18" 5 sided cube, hooked them to a 1000 watt amp, and pointed the open end into my media room (1764 cu ft) from the front wall ceiling, I'd be on track? Lou
That would be a suitable layout for a pair of these woofers.

Would two of these in-wall mounted 6 ft. apart as an IB setup with an extra large attic space behind them, powered by a Crown XLS 2500, give any sub-20Hz performance? Or would a single UM18-22 be a better choice (powered by a bridged Crown XLS2000)? Thank
Both choices will have similar displacement although the dual 15's would have to work less for it, meaning lower distortion. These should be able to reproduce 20 Hz but it really depends on room size and the output you want.

what size manifold opening (square inches) would be most appropriate for a 2 driver IB configuration? how about for a 4 driver configuration? and what would you recommend as the best material to cover the manifold opening with?
~300 square inches will work fine for two or four of these. An 18" five sided cube would be perfect for either quantity. We have different grill fabric options that would work to cover the opening.
