I'm looking to purchase several speakers for the rear surrounds of my system. I have a door placed to the left of the listening position, so I'd have to place wall mounted side surrounds either in front of or in back of the listening position. So the dealer I visited suggested ceiling mounted B&W CCM80 speakers for the side surrounds. The back of the room is partially open to the kitchen with the back wall less than 1/2 the width of the room, so he also suggested mounting the B&W CWM in-wall center channel speaker in the ceiling for the middle rear speaker of a 6.1 setup. Any advice? I have Vandersteen 2ci for the front and a B&W LCR600 for the front center.
