I am continually frustrated by the center channel performance of my 5.1 system. My front speakers are Quad 22Ls, with a Quad L-Center, so things should be matched up pretty well, at least in theory. But in real life, not so much. For most HD broadcasts, and for DVDs, I find I have to boost the center about +4db, else the dialog gets overwhelmed by music and other sounds coming from the other speakers. Or, if I don't boost the center channel, I end up turning up the volume, and getting overwhelmed when some explosion or other loud event happens.
I should also note that much of this is source dependent: some DVDs and HD broadcasts sound fine, others have seem to have very low volume on the center channel.
Is there a good solution for this? One idea is to revert to two speakers, with a "phantom center"; this should match the volumes correctly. Or make more use of the Dynamic Range Control on my receiver, so turning up the volume to hear the dialog won't result in losing my hearing when some on-screen explosion takes place.
Any ideas or comments appreciated.
