CS 66

Pinnacle New CS 66

Pinnacle's new CS 66 is designed to fit inconspicuously in the corner of your room. This patented corner loaded subwoofer (US Patent #D626938S) features an innovative sloping front baffle design to more effectively couple the sub's output with the room corner resulting in deep and accurate bass performance.  Dual 6.5” woofers are paired with our state of the art 350 Watt amplifier to deliver a volume and depth of bass typically only possible from a much larger woofer in much a larger cabinet. Finished in a beautiful, heirloom quality piano gloss, this first of its kind subwoofer is certain to suit any décor.
