The Polk Signature Elite ES12 subwoofer enhances any home theater or music system with deep, precise bass. Featuring a high-excursion 12-inch woofer and a powerful Class D amplifier, the ES12 delivers rich, immersive low frequencies that you can feel.
Polk’s Power Port technology, combined with a rigid, acoustically optimized cabinet, minimizes distortion and turbulence for smooth, clean bass output. Dual Power Ports ensure deep and detailed low-frequency response, while advanced DSP with 32-bit floating point processing enhances clarity and transient response. The ES12’s Time-Smart Phase Control allows precise system blending with 360-degree phase adjustment, ensuring seamless integration with your main speakers.
A front-firing design allows flexible placement, making it ideal for various room layouts, including placement against walls or on shelves. The adjustable 4th-order low-pass filter and multiple connectivity options, including LFE and stereo line-level inputs, provide compatibility with a wide range of amplifiers and receivers.
The ES12 is engineered for durability and performance, housed in a stylish, well-braced MDF cabinet that reduces unwanted resonance. With an auto-sensing power-save mode, it minimizes energy consumption when not in use. Whether for movies, music, or gaming, the ES12 brings an impactful low-frequency experience to any setup.
