I need some help. This is gonna be a 7.1 setup. I'm looking for some surround side and rear speakers that needs to be hang on wall/ my front speakers are Pioneer SP-FS52. the room is about 12'x16'. behind the couch, I have about 4' space to the wall. I am planning on to get the Klipsch KS-14 as my side and rear. Should I go with the Klipsch RS-41 II which is a bit better? What match better with the Pioneer?
