[QUOTE="Bennett Prescott, post: 16940, member: 4"] Re: Itech 8000/Danley? A clip limiter will do fuck all to protect loudspeakers from overheating unless it is set way, way low. Amplifier clipping is a sonic issue, although most amps sound fine with their internal clip limiters (which are also more accurate, usually). A fast peak limiter can be used to prevent overexcursion, but that doesn't appear to be your issue. Two amplifiers delivering the same amount of continuous (RMS) power will destroy the same loudspeaker in the same amount of time, assuming they are delivering the same signal that is over the loudspeaker's ability to handle. The room, and perhaps room nodes or alignment, is surely your issue here. I am sure the TH215s cannot handle 2500w continuous power, that is surely a ''program'' number that accounts for crest factor (peaks) in the signal. You should certainly be using a big amp to allow them to provide maximum sound quality and output, but you need a gentle hand on the throttle, an RMS power limiter, or both.
