Polk Audio Subwoofer Signature Elite ES12, Black

Impactful bass for expansive soundscapes

Enhances the largest home-theater and music systems—from stereo to full Atmos—with deep, immersive bass you’ll feel in your bones.

Seamless sound

Sophisticated settings like Time-Smart Phase Control make system blending effortless, for smooth, even sound.

Fits anywhere

With a narrow cabinet and front-firing orientation, the ES12 sounds great anywhere—even against walls and on shelves.

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.

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.
