The UltraSonic is our new top of the line powered subwoofer. Our state of the art 800 Watt amplifier drives dual 12” woofers in a bipole configuration. With a maximum output level of 116.5 dB (louder then a jackhammer!), the UltraSonic will fill an oversized room with oversized bass! But the UltraSonic is not just loud, it is also accurate and deep, very deep, down to 20 Hz.  It is finished in our beautiful Black Diamond piano finish with elegantly curved sidewalls for a sophisticated, sleek look. Don’t sacrifice beauty and style for massive sound – get both with Pinnacle!
