  3. Very Satisfied

    Posted by Mitch on 30th Mar 2015

    I re-conned the sub with zcon softies. I have a taramps 5K on it for my daily driver. 6.5 cube slot port box. Nothing special. People can't believe its just one sub. The 2500 RMS is a joke. I have 14.6V steady at full tilt so I know this sub is getting some real Brazilian power. This sub easily handles double rated if you know how to set gains properly. My other SUV has 4 SQ HDC4 18's so I know what a heavy system feels like and for being a single 18 it definitely doing its job. AA has some very HQ subs. I recommend this to anyone who's looking for quality.

  4. Hits Hard

    Posted by Alex on 6th Jul 2012

    I bought this sub from SSA back in November 2011. This sub is excellent. Exactly the kind of quality I was expecting from Ascendant Audio. I have 2500 watts going to it and it takes it like a champ. Stays cool, doesn't smoke. I have it in a 6cu box before displacement (for SQ). Seems to like it. Very punchy even on fast metal bass. If you want it for SPL you'll want to put it in a bigger box. This thing destroys the lows. I highly recommend this subwoofer. I can see myself enjoying this for many years to come. Just make sure that you know what you're doing before you buy high end equipment like this. You need to make sure that you are NOT sending clipped signals to it. If you feed it clean power you'll be smiling every time you get in your car.

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.
