My family room will be used for music listening and movies (until my basement is done). The dimensions are 17x21 with 38 foot ceilings. My wife prefers the B&W 805 Signature Series (bookshelf) and I like them too. However I'm concerned that they will not have much of a presence in such a room. If that is the case I'm thinking of getting the B&W 803 or 804s (floorstanding). The speakers will be powered by a 200w amp. Any thoughts or opinions are appreciated.
