I have a room 10x15 that I am looking to add a theater to. I am considering a 5.1 system since the room can't accomodate a 7.1 system due to its size. For the fronts and surrounds I want to use bookshelf speakers. What should I consider? Was looking at the B&W 805's and monitor audio gold reference and both seemed a good choice. Any other suggestions or comments on speakers or 5.1 or 7.1 set-up?
