High-powered amplifier
Provides power and control to deliver impactful bass that fills the largest rooms, offering definition, dynamics, and clarity at any volume.

Forward-firing long-throw woofer
A front-facing, high-excursion 12” woofer produces deep, defined lows down to 18 Hz. It’s the difference between bass you hear and bass you feel.

Acoustically optimized cabinet
A rigidly built, ported cabinet is reinforced with FEA-optimized internal bracing that minimizes resonances and coloration, ensuring clean, effortless reproduction of low-frequency detail.

Two Internal port
Two Polk Power Ports minimize turbulence, reducing noise and distortion that mask midrange clarity. Their frontfiring configuration means accurate bass no matter where you place your subwoofer.

Advanced DSP
High-resolution 32-bit floating point processing with group delay-minimizing filters and precision limiters enables clearer bass with crisper transients.

Time-Smart Phase control
Time-Smart Phase Control provides 360 degrees of phase adjustment centered around lowpass filter settings, ensuring precise system blending. Adjust polarity in 45-degree increments, displayed on LED indicators.

4th-order lowpass filter
An adjustable 4th-order lowpass filter provides precise frequency control, for seamless integration with main speakers and superior overall system performance with open, balanced lows and mids.

Power-Save mode
An auto-sensing power supply reduces power consumption when the subwoofer is not in use.
