[QUOTE="THATpurpleKUSH, post: 8739748, member: 615398"] Meca 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. [/QUOTE]
