MTX Audio Thunder Square 12-Inch Dual Subwoofer; 4-OHM (Universal; Some Adaptation May Be Required)

Built for SPL
S65 Series square subwoofers are built to deliver exceptional SPL and the most bass for your buck.
The S6512-44 is a 12" dual voice coil, 500-watt, dual 4 ohm square car audio subwoofer built on the MTX tradition of getting more than expected.
Patented Technology
The surround geometry on the S65 Series, protected by US patent #7,275,620, increases the effective Xmax of the subwoofer, resulting in higher SPL and volume displacement, which translates to more dB that comparable subwoofers from other manufacturers. This patented design makes the S65 the loudest 500-watt square subwoofer in the market today.
Cool Under Pressure
Spider Plateau Venting is a mechanical cooling process that circulates hot air for cool air at the voice coil as the subwoofer continuously cycles. The constant movement of hot air out and cooler air in, targeted directly at the 2.0" high temperature voice coil increases reliability and longetivity.
Radial Ribbed T-Yoke
The specially designed backplate on the S65 Series not only gives it an impressive stance, but acts as an additional medium to conduct heat away from the voice coil. The increased surface area of the backplate dissipates additional heat ensuring the S65 subwoofer plays with lower distortion for extended periods.
