I don't know if this helps or not, but I have a pair of the E15HP2's (4000 cubic room w/ full acoustic treatment).
If I'm watching a movie with my wife I can use both subs (main system volume is lower than watching a movie myself).
If I'm watching a movie alone, and she's upstairs on either the main floor or the 2nd story floor, I have to turn one of them off, and the volume down on the other. It's amazing how much these things can pressurize a room.
I thought about a pair of G22's, but didn't like where the plate amp is situated.
Best of luck going forward whatever your decision is.
