The JH5512-04 12" subwoofer sports a rubber surround that's stitched directly to the polypropylene cone for extra strength, then rolled to maximize cone excursion so this sub'll move some air. The high-temperature copper voice coil lets this Jackhammer sub deliver powerful bass with smooth, piston-like precision. 

MTX's patented Spider Plateau Venting keep the inner works cool, so this sub can rock for hours. The stamped steel basket adds strength and support, while a rubber boot and distinctive dust cover lend this sub an extra dash of style.
