HTS 12 Subwoofer

The Polk HTS 12 subwoofer enhances home theater and music listening with powerful deep bass. It features a long-throw Dynamic Balance 12 " driver, patented Power Port® technology and a state-of-the-art 400W Class D amplifier. Easily to access controls for volume, low pass filter, and phase correction. Connect via LFE (unfiltered / low pass disabled) or stereo line level RCA inputs.

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 smoothly transitions air flow from the speaker into your listening area for deep, extended bass impact while minimizing turbulence, distortion, and port noise. At the port tuning frequency, Power Port® equipped subwoofers have 3dB less port noise than similarly configured subwoofers without Power Port®.

Dynamic Balance Driver

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.

American Modern Styling

Curved edges offer a sensual yet powerful look that fits with any home decor—available in a stunning black washed walnut or classic brown walnut finish.

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.

Universal Compatibility

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

Quality Crafted Cabinet Design

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