What I did:
This will help cut down on the bass, but is more of a solution to help tweek the sound interactions in the room, but...
Buy 1/4 inch plexiglass and I drilled some hole to attach my screw and nuts that I attached wire hangers to to hang like a picture, a 4 point hanger is recommended, then glue a sound insulated ceiling tile to it. Then bunch up some fiberglass insulation and wrap it all in your favorite fabric..I used a dark red (burgandy) crushed velvet fabric. Hang this directly behind your speakers, and make as many as you need. I'd say one behind front speakers for sure. This still won't let you crank it, but should help, and like I said, should help dampen the room.
