Steuspeed: I agree... unless you sit off axis the Wilson 2 channel will re-create the center...
There is a Caveat! - You make no mention of your surround processor... Meridian, Theta or something is required to try to get some fidelity out of music sountracks..
If the music/soundtrack is too loud and voices are recessed then check these things..
If you aren't using a surround processor you are losing the dialog information from most DVD players (check to make sure they are outputing in 2 channel stereo). Even if you are using a surround processor make sure that is has an option to set no speaker for the center or has a specific phantom mode. Check with AVIA test DVD to setup audio.. Digital Video Essentials might help but the old version wasn't as good.
