Hi Stephen,
Follow-up on speaker placement. You were exactly right about the Synergy S2 Surround speakers. They sound great on the back wall. I took your advice and did not use the Omnimount speaker mounts also. The built-in speaker mount is all that is needed. Gonna send those back for the return of my money. Watching a movie played by my Sony RDR-GX7 DVD player/recorder using a Yamaha HTR-5750 A/V receiver and the Klipsch speakers(F2's, S2's with center channel and subwoofer) on a Samsung 61" DLP television is absolutely amazing. As you can see I am very happy with the sound results. Thanks for the great support over the phone and I love my Klipsch's. A very happy customer...
