Polk Audio HTS 12 Powered Subwoofer

Features

12" Polypropylene Dynamic Balance Woofer:

  • The HTS 12 houses a front-firing 12" polypropylene long-throw woofer with rubber surround for deep, accurate bass. The woofer incorporates Polk's patented Dynamic Balance technology and is Klippel optimized to provide clean, clear bass, better linearity, lower distortion, and greater durability.

200W Class D Amplifier:

  • The Polk HTS10 employs a 200 watt (RMS) / 400 watt (Peak) Class D amplifier for dynamic bass performance.

Power Port Technology:

  • The Polk HTS 12 powered subwoofer utilizes floor-firing patented Power Port Technology for deeper bass response and reduced port noise. 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.

Non-Resonant Enclosure:

  • The powered sub's strong, rigid, and acoustically inert curved enclosure reduces unwanted internal standing waves for less audible coloration. Its non-resonant Meddite MDF construction, with extra bracing and thick baffle, ensures a more lifelike sound.

Controls:

  • Built-in controls for variable volume, low pass filter, and phase let you tune in optimum bass levels. All controls are found on the rear-panel of the powered sub.

Volume:

  • The rotary volume knob adjusts the volume of the powered sub relative to the other speakers in the system.

Low-Pass Filter:

  • The variable low-pass filter is adjustable from 40-160 Hz. The low-pass filter is only active for the powered sub's stereo RCA inputs. The low-pass filter is deactivated when using the powered sub's LFE input.

Phase:

  • The phase switch allows you to select 0-degrees (normal) or 180-degrees (reverse). If the bass sounds muddy or unclear, toggling the phase control can sometimes strengthen the bass attack.

Line-Level Inputs:

  • The Polk HTS 12 powered subwoofer is outfitted with an unfiltered LFE input and filtered stereo RCA inputs (subwoofer cable not included).

LFE Input (Unfiltered):

  • The LFE input consists of an unfiltered mono-RCA jack (the LFE input bypasses the powered sub's variable low pass filter). Using the LFE input when connecting to an AV receiver or integrated amp with a filtered LFE output and built-in crossover control.

Stereo RCA Input (Filtered):

  • The Stereo input consists of a left & right RCA jack (both jacks are filtered). Use the Stereo input when connecting to a receiver or integrated amp that does not have an LFE output, but does provide a preamp output.

Auto & DC Power On/Off:

  • The powered subwoofer will automatically turn on when an audio signal is received and off when there is no audio signal for about 20 minutes. There is also a 12V trigger input on the back of powered sub which allows it to power on with your receiver or integrated amp that features a 12V trigger output (the 12V trigger provides a faster auto on/off).

Note:

  • There is a switch on the back of the powered sub that indicates which power on/off method you will be using - Auto or DC.

Placement:

  • You may place the powered subwoofer anywhere in your room, but it will perform best when it's on the same side of the room as your system's front speakers. Also, placing the subwoofer near a wall or in a corner will increase its loudness.

Frequency Response:

  • The overall frequency response for the subwoofer is 22-180Hz, and the -3 dB frequency response is 28-120Hz.
