The Big Woofer Sound in the Small Woofer Box SM

Sit back, relax and enjoy the deep authoritative and convincing bass from our incredibly tiny SubSonic subwoofer.  Pinnacle's engineering marvel is a diminutive 7 7/8" cube that shatters the previous performance boundaries of microsized boxes. Now you no longer need to compromise by choosing between superb bass or a visually discreet, unobtrusive product. 

Most potent subwoofers are housed in physically large boxes that encroach on your living space. Not so with the SubSonic! We achieve spectacular results with our proprietary subcompact amplifier design mated to a bipole pair of specially customized 6 1/2" woofers.  The impressive 350 Watt output produces astonishing bass levels, deep, clean and penetrating down to 28 Hz (-3dB) with a maximum output of 107.5 dB SPL. Amazing results from such a tiny subwoofer!

The SubSonic makes its presence known and felt even if discreet placement makes it hard to spot in your living room!

Our subwoofers deliver awesome, room-filling, deep, accurate bass from incredibly tiny cubes. These Sub-Compact Powered Subwoofers employ high powered amplifiers and driving dual active woofers arranged in a bipole configuration.
