[QUOTE="Bennett Prescott, post: 24989, member: 4"] Re: Help me understand system limiting- setting it BJ, I never intended to reply that peak limiting is useless! However, the reason for peak limiting is to prevent over excursion. If you are not having an over excursion problem, or if you do not have enough amp power to exceed the excursion limits of your drivers, then you do not need to worry about it. Your DSP does not allow you to do thermal limiting, which I think is a greater benefit since one can use amp size as a "free" peak limiter, but you need thermal limiting to keep your drivers out of power compression and safe from real long term abuse. Almost everyone has enough amp to burn up their drivers, but I doubt most people have enough amp to destroy their drivers suspension. Now if only I had limiters that allowed sidechain EQ to truly optimize to the thermal and excursion characteristics of the driver in the enclosure, as well as motor thermal modeling to allow me to adjust the peak limiter based on the likely impedance of the voice coil. P.S. The limiters in the Crown iTech and iTech HD series amps are fucking great. I wish I had them damn everywhere. Saves me a lot of math, solves the problem. [/QUOTE]
