I'm getting ready to add a pair of rear channel speakers to my system to move to a 7.1 configuration. Currently, I have Polk RT55i's for my mains, a CS400i for my center, f/x500i's for my side surrounds (dipoles) and a Velodyne VA-1250X sub. My room is rectangular, 11 X 25 with the TV and mains along the short wall. The rear speakers will be going on the back wall and not mounted on stands. For those of you who have tried using direct and dipole speakers as your rears, what did you end up going with and why? Thanks for your inputs!!! ------------------ "We're hosed. We lost the remote."
