Dynamic Balance Woofer
Take movie, TV, music, and game sound to thrilling new depths
A 10” long-throw, high-excursion woofer produces the deep, effortless bass that Polk is famous for, all the way down to 24Hz. You won’t just hear it—you’ll feel it in your bones.

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

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.

Customize bass for seamless low end
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.

Timbre-Matched

Flexible I/Os
Makes the right connections
Plug in and power up in seconds with versatile line-level/LFE inputs that are compatible with most audio receivers.
