When I first got my Mystique, a couple of the speakers were really bad. The voice coils wouldn't stay in the gap, they would wiggle around so to speak, and pop out of the magnet. If you smacked the door, they would pop back in, and play. Until a bass note sent them back out again. After 3 days, my old CD player went in, and after a week my Cerwin-Vega Accurate Image 6.5" components went in.
