Its sleek cabinet complements Signature Elite systems and fits anywhere.

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

Forward-firing long-throw woofer. A front-facing, high-excursion 10” woofer produces deep, defined lows down to 22 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.

Versatile inputs and precision control. 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.
