I'm going to be getting a pair of B&W CDM 1NT's to act as my surrounds. Due to the layout of my room, speaker stands are probably not an option so I'm going to have to set them up on brackets or something and install them onto the walls. My questions are: will having the speakers relatively close to the walls like that have a detrimental effect on the sound? Is there a preferrable way to mount from a wall? Is there another option (i.e. I've heard of people mounting from the ceiling)? Thanks in advance!
