Hello all.I just purchased a pair of rs-3 for my rear surround.I have Klipsch epic cf-3 up front and cv-4 for the center all powered by a marantz sr-19 receiver.My question is first how will these speakers match up sound wise to my front stage? Also I am going to mount the RS-3s on the wall directly above me about 3 feet from my head.The wall is right behind the couch.I am worried that since they will be above me and the speakers will be faceing strait ahead fireing toward the front that i will not get true surround sound. One more thing,Does anyone know if they make wall brackets for these speakers and if so what the part number is?Also is there a place i can order them from an online store. Any help would be great.
