Polk Audio Signature Elite ES8 8" 100W Subwoofer

Because the Polk Audio Signature Elite ES8 8" 100W Subwoofer is engineered to elevate your home theater and music listening experience, it delivers deep, defined bass that enhances compact audio systems. This front-firing subwoofer is powered by a robust Class D amplifier, optimized with advanced Polk DSP technology, ensuring impactful bass with rich dynamics and unparalleled clarity, even at the highest volumes. The ES8 subwoofer's high-excursion 8" woofer features a mineral-filled polymer cone, mathematically optimized for powerful, clean output, reaching lows down to 28 Hz. This design ensures you not only hear the bass but feel it, transforming your entertainment experience.

The acoustically optimized cabinet is rigidly built and reinforced with FEA-optimized internal bracing, minimizing resonances and coloration for clean, effortless reproduction of low-frequency detail. The integrated Polk Power Port technology reduces turbulence, delivering clean, musical lows without air noise or distortion, while its front-firing configuration allows for flexible placement, ensuring accurate bass regardless of the subwoofer's location.

Advanced DSP with high-resolution 32-bit floating point processing and group delay-minimizing filters enhances bass clarity and transient response. The Time-Smart Phase Control offers a full 360-degree phase adjustment, centered around lowpass filter settings, for precise blending between the subwoofer and main speakers. This is complemented by a rear-panel digital control that adjusts polarity from -135 degrees to 180 degrees in 45-degree increments, displayed on an LED level indicator array.

The ES8 subwoofer features a sophisticated 4th-order lowpass filter, fully adjustable via the back panel, ensuring optimal integration with main speakers. This filter provides sharper frequency cut-off and steeper attenuation, effectively isolating bass frequencies and enhancing overall clarity for a smoother, more balanced full-range sound, whether you're watching action-packed films or enjoying your favorite music tracks.

Designed with a sleek, narrow profile, the ES8 subwoofer fits seamlessly into any space, from directly against walls to inside cabinets, without compromising sound quality. Its compact, durable MDF cabinet, finished in elegant black vinyl with curved edges and rounded corners, complements the Polk Signature Elite speaker series and integrates effortlessly into any decor. Removable grilles offer customization options to suit your personal style preferences. Additionally, the subwoofer features a power-save mode with an auto-sensing power supply, reducing power consumption when not in use, making it both a powerful and efficient addition to your home audio setup.
