Used Polk Audio Signature Elite ES12 12" 300W Subwoofer

Take your home theater and music experiences to the next level with the Polk Audio Signature Elite ES12 12" 300W Subwoofer. This front-firing powerhouse is engineered to deliver impactful bass that enhances even the largest home-theater and music systems. At the heart of the ES12 is a robust 300-watt Class D amplifier, meticulously optimized with advanced Polk DSP technology. This ensures that you experience deep, defined lows, rich dynamics, and unparalleled clarity, even at the highest volumes, filling your space with breathtaking sound.

The ES12 features a proprietary 12" high-excursion woofer with a mineral-filled polymer cone, designed for superior stiffness and stability. This forward-firing long-throw woofer is mathematically optimized to deliver powerful, clean output, reaching down to an impressive 18 Hz. This means you won't just hear the bass you'll feel it.

Housed in an acoustically optimized cabinet, the ES12 is reinforced with FEA-optimized internal bracing to minimize resonances and coloration, ensuring the clean, effortless reproduction of low-frequency detail. The cabinet's design includes acoustically aligned ports built into the same baffle as the woofer, optimizing energy distribution throughout the room for an immersive listening experience.

The subwoofer is equipped with two internal Polk Power Ports that minimize turbulence, providing clean, musical lows without the air noise and distortion that can obscure midrange clarity. Advanced DSP technology, featuring high-resolution 32-bit floating point processing, employs group delay-minimizing filters and precision limiters for clearer bass with crisper transients.

Time-Smart Phase Control offers a full 360 degrees of phase adjustment, centered around lowpass filter settings, ensuring precise blending between your subwoofer and main speakers. The rear-panel digital control allows for polarity adjustments from -135 degrees to 180 degrees in 45-degree increments, displayed on an LED level indicator array.

The ES12 also includes a sophisticated 4th-order lowpass filter, fully adjustable via the back panel, for optimal integration with main speakers. This filter provides a sharper frequency cut-off and steeper attenuation, effectively isolating bass frequencies and enhancing overall clarity. Whether you're watching an action-packed movie or enjoying your favorite music, you'll experience smoother, more balanced full-range sound.

Designed with a power-save mode, the ES12 features an auto-sensing power supply that reduces power consumption when not in use. Its compact, durable MDF cabinet, finished in sleek black vinyl, complements Polk's Signature Elite speaker series. With elegant curved edges and rounded corners, the ES12 seamlessly integrates into any decor. The removable grilles offer customization options to suit your style preferences.

Thanks to its narrow profile and front-firing woofer and ports, the ES12 can be easily placed anywhere from directly against walls to inside cabinets without compromising sound quality. Experience the powerful, larger-than-life bass that brings new depth and dimension to all your home entertainment with the Polk Audio Signature Elite ES12 Subwoofer.
