Thanks No_money and hifinerd,
As for loud, lets say reference levels. I can give a better description of what happens. First off, I get very little bass out of these, not uncommon. Using a Velodyne 18 for Home Theater, I am not concerned, however, in 2 channel, all low frequencies leave the room. So as I turn the Classe SSP-50 up to about -35 to -40 (-60 is the max) with each channel set at about +6dB (problem? should it be 0?) the two front channel, using balanced cables, clip. This means, the speaker continue playing, the amp still works, but the two dummy (good for people like me) lights come on sporatically reading CLIP. When I look at the bass driver it is COMPLETELY maxed, moving as if there is TOO MUCH power.
Keep in mind, the volume is VERY loud at this point! I just find it odd that the other speakers do not clip. I believe I have them all set at LARGE?!
Ideas?
