Product Description

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.

    I'm going to order one soon but can someone tell me if looks like it does in the picture with an exaggerated dust cap and triple stacked magnet about the size of the cone/ surround itself??

    This subwoofer will play hard and low any time for all music. If you want play street bass from 25hz to 50hz this is best choice. Wonderfull daily groundpounder, you just smile ever day with every notes of bass. With tuning at 32hz, you can play every song from 25hz to 50hz with great lineartity. Thank you AA/Fi for this nice sub.

    What a sub. This is by far the best sub I have ever heard or owned. The craftsmanship is very good. Running this at .5 ohm on strong electrical and it takes it with ease. Will definitely buy from ssa again as they answered my emails ASAP.
