ripple_fx1: Thanks. Again, it's curiosity my need to learn anything and everything, and not necessarily putting any of this to practical use. I don't plan on killing my HS80's. If I'm being completely honest, not too many of those pages were speaking to me at all, due a relative lack of circuit knowledge.

I may not know exactly how much I'm asking here but can you expound on this statement: "but might be a constant reminder that 75 watts of "dynamic power" isn't a lot of headroom and woofer beware." Maybe a mini-lesson on power to output ratios or something?
