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.

Larger-than-life bass with unrivaled precision

Dual Power Ports
Two Polk Power Ports minimize turbulence, reducing noise and distortion that mask midrange clarity.

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.
