Help with center speaker (dialogue distortion)
Here's my setup
Receiver: Onkyo sr502
Speakers: Celestion AVS302?, the set that was on clearance at Best Buy about a year ago.
DVD player: Sony NS50p, coaxial
14 gauge wires
Ever since I hooked up HDTV to the receiver last week, I've noticed distortion on the center speaker when watching DVD's. When someone is yelling (i.e. Al Pacino in Heat, UFC announcers), the center speaker kind of "cracks". I've checked the wires and they are fine. What's weird is that gunshots and sound effects do not crack. It's only when someone is talking that the center gets distorted. Any advice is appreciated.
btw, crossover frequency is at 80 hz, treble at 0 and bass at 4.
