I've had a Force planted in an uncarpeted corner of my living room for a couple of years now, and I've been very pleased with my setup. The sub integrates seamlessly in my system (Sapphire XLs in front, Emeralds in back), with virtually no directionality in the bass tones during music listening (at least, not to my ears; YMMV) and very modest directionality on home theater (we're talking major bass output, the kind that shakes the furniture). My living room is medium size, roughly 18'x20'x9'.
