Features

• 12-inch Dynamic Balance Composite Woofer Driver creates "tight", musical bass.
• Downward firing port couples to the room for more bass impact.
• More powerful motor structure for a higher BL product,(the measure of the motive force applied to the cone) results in louder, deeper and punchier bass than previous Polk woofers in this price category.
• Klippel Optimized woofer - By using a state-of-the-art Klippel Distortion Analyzer, Polk engineers were able to optimize the woofer's motor structure, voice coil alignment and suspension for the best possible performance even at extreme listening levels.
