For all feed back . . . . . I'm currently running an Onkyo 703 with a pair of Boston Acoustics CR 65s up front (inside the wall system flanking a Sony Wega 36", my center is a Polk CS1, and my intent is to put in the Polk M20 Towers in the rear......as opposed to hanging some Bose Jewel Cubes in the rear. (I don't really want to hang anything up on the wall although the height should really enhance rear audio) The towers would solve my problem with hanging audio from the walls. Feedback?? By the way I'm running a Velodyne DSP 10 sub, so my bottom end is covered.
