The S65 Series

The S65 Series is designed for enthusiasts that want to add extreme bass to their system. With more surface area than a standard round subwoofer and patented corner geometry that increases Xmax, the S6512-44 square subwoofer delivers exceptional volume displacement that translates to exceptional SPL. The woofer features dual layer cooling technology with Spider Plateau Venting technology that utilizes the subs movement to cool it as it plays and a radial ribbed t-yoke dissipates heat away from the voice coil through the back plate, so it doesn't overheat even under intense use.
