Looking for an amp for my subwoofer - it will need about 400-500 watts at 4ohm. I've narrowed it down to the QSC RMX 1450 and the Peavey PV 1500. I know the reputation QSC has for quality and durability, but I don't know much about Peavey. Both are about the same weight, both are an AB class amp, QSC delivers 450 watts, Peavey delivers 500 watts, both have variable speed fans, both are solid down to 6hz, both are $400 new, basically on paper they seem equal. I just don't know much about Peavey and would like to hear from some who do. If not, I know the QSC is a safe bet.
