Features & Specifications



Polk Audio HTS12 12″ Subwoofer with Power Port Technology

The Polk Audio HTS12 subwoofer enhances home theater and music listening with powerful deep bass.

Deep Bass for Home Theater and Music

Whether you’re installing a new set of surround or ATMOS speakers, adding a second subwoofer for the ultimate home theater experience, or just need more core-pounding impact from your favorite music, the HTS 12 delivers the powerful bass you crave with its long-throw 12” driver, patented Power Port technology and 400W Class D amplifier

Patented Power Port Technology

The Power Port floor-firing design on the Polk Audio HTS12 smoothly transitions air flow from the speaker into your listening area for deep, extended bass impact while minimizing turbulence, distortion, and port noise.

Effortless Bass, Bass You Can Feel

Pair the HTS 12 with any of your Polk speakers for that deep bass impact you can feel across all your home theater and music needs.

Dynamic Balance Drivers

Front-firing 12” driver with our patented Dynamic Balance technology is Klippel optimized to provide clean, clear bass, better linearity, lower distortion and greater durability on the Polk Audio HTS12 subwoofer.

Complete Control

Built-in controls for variable volume, low pass filter and phase (0/180°) for optimum bass levels. Set power toggle to Auto on/off or DC control (12V trigger) for fast and easy on/off power switching in the sub and other home theater equipment—all easily accessible on the back panel.

Quality Crafted Cabinet Design

Strong, rigid and acoustically inert enclosure reduces unwanted internal standing waves for less audible coloration with the Polk Audio HTS12 subwoofer. Non-resonant Meddite MDF construction, with extra bracing and minimum thick baffles, ensures a more lifelike sound

Universal Compatibility

Connect via LFE (unfiltered / low pass disabled) or stereo line level RCA inputs—complements any home theater system (cables not included).
