I'd be very interested in hearing opinions about using a center speaker vs. going with a "phantom center" arrangement (at least for my particular set-up). I'm looking at getting Sierra Lunas and a Rythmik L12. It will be a 3.1 (or maybe 2.1) arrangement. I mostly listen to music, but would appreciate better sound for movies too. The area is open floor plan, but seating for music/movies is within eight feet of the speakers and pretty well centered. L/R speakers can be placed 9-10 feet apart at ear level on shelves on either side of tv. I'm sure my wife would like the clean look of no center speaker (and it would keep me from having to re-install the tv about four inches higher, though I don't mind if it really improves the sound). I've read all I can find about using a phantom center, and it's intriguing, but I would love to hear what you guys think. I'll be using a Denon AVR in the 100 watt range, probably. Thanks in advance!
