Just got a new receiver, denon 2802, and so far my velodyne VA1215 (rated at 250w rms, peaks at 400w) has experienced clipping on 2 occasions when the bass really rumbled, although some movies that rocks on the bass don't seem to have any problems. I've set Xover at 80. Volume on the sub is rarely above 1/4. Does anyone know if this is due to the receiver, or maybe incorrect settings on sub. Would appreciate any input from velodyne VA1215 sub owners. thanks.
