Each subwoofer is 8-inches in diameter and are designed to work in pairs.  The rugged cabinet and chassis design, along with the mounting bracket promise to all but completely eliminate wall resonances.

Matching X-Series subwoofer amplifiers contain separate EQ and clean power.  For even low frequencies the company recommends for two or four subwoofers to be used.  The subwoofers will be shipping soon, but no price has been released.  They are sure to be on display at CES 2009.
