Ohh, ok I've heard of "box"/ impedance rise before, but never really had it explained or known how drastically it effected power. How big of an amp should I need then. A 2k, 3k, or more? Or would it be a better idea to build the box see how far under tested power my amp does and buy an amp using that numberMeca clamps actual power and combines that with the cone area in sq inches to determine pressure class. A 15 on a 1200w amp should be in the lowest possible pressure class. If its a true 1500 class, you will be seriously outgunned because the impedance rise puts you at roughly half of the amps rated power which is about 600 +176 sq in of cone area so that puts you at 767 which is half of what is allowable. It would be like bringing a safety box cutter to an AR15 shooting match.
