Anything for this room has to be sealed. 10'x12'x9', speakers on a dresser, with the fronts about 1.5' from the wall, and the listening position up against the rear wall. Lots of boom. Everything I've tried ported was too much bass. Right now I have a pair of kit 41's from DIY cable sealed because ported was too much. My only worry with the extremis is the 80db sensitivity, all I have is 30 watts. But for a bedroom system I don't need it too loud.
