Dynamic Balance Woofer

A 10” long-throw, high excursion woofer produces the deep, effortless bass that Polk is famous for, all the way down to 24 Hz. You won’t just hear it— you’ll feel it in your bones.

Ultra-Efficient Amplification

Enjoy powerful, clean sound at any volume. A robust, 100-watt peak, Class D amplifier delivers consistently pristine sound, whether you’re dialing things down or turning it up to 11.

Rigid, Ported Cabinet

Acoustic innovations keep bass sound pure. A critically braced cabinet with down-firing port minimizes resonances and sonic interference, for defined, room-filling low end.

Dial In the Perfect Bass Sound

Customize bass response for seamless low-end immersion. A consistently variable crossover, low-pass filter, polarity switch, and subwoofer volume control let you fine-tune bass response—whether you prefer subtle low-end enhancement or room shaking rumble.
