Defined Bass

High-powered amplifier

Provides power and control to deliver impactful bass in compact spaces, offering defined lows, dynamics, and clarity at any volume.

Bass You Feel

Forward-firing long-throw woofer

A front-facing, high-excursion 8” woofer produces deep, defined lows down to 28 Hz. It’s the difference between bass you hear and bass you feel.

Clean and Effortless Sound

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.

The perfect complement to compact Signature Elite systems

INTERNAL POWER PORTS
A Polk Power Port minimizes turbulence, reducing noise and distortion that mask midrange clarity. Its front-firing 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.
