I own the economical Polk Audio RM 6750 5.1 setup. Because of moving arrangements, I'm having to compress layout of my home theater to the use of a very small TV (23" diagonal). I desire to retain a 45 degree viewing arc as with my last setup (a full blown front projector with larger speakers), which means I'm sitting 2' away from the 23" screen. This forces me to not use the center channel, since at this proximity to the screen, the usage of a center channel would seem to pull down the sound image too far, given my seating distance. I plan on using the front two speakers as a "phantom center." Given my situation, is this "phantom center" the best option? Also, is 2.5' too close to speakers (even if they're at a 60 degree listening arc) to preserve stereo imaging and sound-stage? Your advise is most appreciated.
