10" Polypropylene Dynamic Balance Woofer: The HTS 10 houses a
front-firing 10" 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.
100W Class D Amplifier: The Polk HTS10 employs a 100 watt (RMS) / 200
watt (Peak) Class D amplifier for dynamic bass performance.
Power Port Technology: The Polk HTS 10 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
- 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 10 powered subwoofer is outfitted with
an unfiltered LFE input and filtered stereo RCA inputs (subwoofer cable not
- 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 25-180Hz, and the -3 dB frequency response is 30-120Hz.
