Planar close to a rear wall? Quad for example?

IMO, for the newer 2905/2805, or older 989/988's they need to be further out from the wall than a foot. Some suggest 3-6 feet (check older threads -- some good info). They do better with some rear breathing room and a sound panel on the back wall.

Pipe dream (if you want to get the best out of these spks).

Sorry

You may want to consider a hybrid like the VMPS RM-30's. They sound nice, and can be placed like that. I mention the VMPS because I've heard them set up that way.....I'm sure there are lots of others too.

I have dipole panels, however mine are placed at 62 inches out.
