The 12" Signature Elite ES12 subwoofer enhances the largest home-theater and music systems. Equipped with a robust Class D amplifier, Power Port™ technology, and Time-Smart Phase Control, the ES12 delivers impactful bass with unparalleled precision. Its sleek cabinet complements Signature Elite systems and fits anywhere.
It is intended for a compatible music or home-cinema system that needs a dedicated low-frequency channel rather than asking the main speakers to do all the work.
Polk’s Power Port technology is part of the published design, supporting the model’s approach to controlled bass performance in its intended system role.
