Mayhem 12 Ascendant Audio 12" 2500W Mayhem Series Subwoofer

The Mayhem Series of subwoofer utilizes many technological advances to create the toughest daily driving sub on the market.  Our engineers have spent hundreds of hours analyzing the various failure modes of other drivers and producing new technologies and solutions to prevent these problems.  Starting with our patent pending Helicool motor system, air is forced through axial cooling channels each time the cone moves.  This positive displacement of air over the coil means increased thermal capacity and power handling.  Using our proprietary suspension assembly techniques, we laminate multiple progressive spiders together for exceptional durability.  Our specially formulated adhesives and adhesive agents have been specifically designed to handle high heat and mechanical stresses of 2500+Watts of power.  The 30mm of Xmax ensures extreme linear ability and monsterous deep bass while the high motor force ensures plenty of skull cracking upper bass as well.

The Mayhem Series is the ultimate in bass performance.
