I have a Martin Logan 5 channel HT setup, but not matching speakers in the rear due to space restrictions behind the seating position (about 5 feet from back of couch to back wall with a computer work station and six foot storage cabinet too). The Powerpoints seem an inspired if expensive solution to this problem since they can be easily mounted on the ceiling for surround duty. I have no room for stand or floor models in the rear and I do not care for the available ML surround choices. Anyone with experience with the Powerpoints in your system? Thanks.
