Polk Signature Elite ES12 12″ 300W Subwoofer

Equipped with a robust 300 watt Class D amplifier, Power Port™ technology, and Time-Smart Phase Control, the ES12 delivers impactful bass with unparalleled precision. Its sleek cabinet complements the rest of the Signature Elite range of speakers and fits almost anywhere.

High-Powered Amplifier

A 300-watt amplifier provides power and control to deliver impactful bass that fills medium to large rooms, offering definition, dynamics, and clarity at any volume.

Power Save Mode

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

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 Optimised Cabinet

The rigidly built, ported cabinet is reinforced with FEA-optimised internal bracing that minimises resonances and colouration, ensuring clean, effortless reproduction of low-frequency detail.

Two Internal Power-Ports

Two Polk Power Ports minimise turbulence, reducing noise and distortion that mask midrange clarity. Their 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-minimising filters and precision limiters enables clearer bass with crisper transients.

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.
