Features
10" Driver: The Polk Audio PSW108 uses a front-firing 10" composite polymer cone driver (with foam surround) for deep,
accurate response with low distortion.
Klippel Optimized Woofer: By using a state-of-the-art Klippel Distortion Analyzer, Polk is able to optimize the woofer's motor
structure, voice coil alignment and suspension for the best possible performance even at extreme listening levels.
Motor Structure: The PSW108 utilizes a powerful motor structure for a higher BL responses (the measure of the motive force
applied to the cone) that results in louder, deeper and punchier bass.
Compression Circuitry: The woofer's Compression Circuitry limits distortion at high volume levels.
Amplifier: The subwoofer is powered by a high-current amplifier producing 50 watts RMS/100 watts dynamic power that
supplies clean power for loud bass and a wide dynamic range necessary to recreate a life-like experience in your home.
Enclosure: The PSW108 features a bass-reflex enclosure with non-resonant MDF construction and internal bracing for deep
bass impact with superior detail and accuracy. The Polk Audio PSW108 is available in a black wood-grain vinyl-wrapped finish.
Front-Firing Port: The powered subwoofer's front firing port allows the woofer to be extremely efficient and provides more bass
impact for your home theater experience.
Not Video Shielded: The subwoofer is not magnetically shielded, so it is not recommended to place it next to tube TVs and
video monitors. Though LCD, DLP and Plasma televisions are not affected by magnetism you should allow at least 18" of
space between the subwoofer and any TV.
Placement: You may place the 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.
Controls
Power Switch: The subwoofer has a 2-way power switch on the rear panel. When On/Auto is selected, the subwoofer turns on
automatically when an input signal is received and off 15 minutes after the signal stops. The LED power indicator glows green
when the unit is on and red when the unit is off.
Volume Control: The PSW108 has a rotary volume control to adjust the volume of the subwoofer relative to the other speakers
in the system.
Phase Switch: The subwoofer's 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.
Low-Pass Filter: The PSW108 offers a continuously variable low-pass filter, adjustable from 80-160 Hz.
Connections
Line Inputs: The PSW108 has gold plated left and right RCA line level inputs. If your receiver or processor has a single
subwoofer line output, you can connect it to either the left or right line input jack, or use a Y-adapter and connect it to both. For
receivers having subwoofer or stereo preamp outputs that do not contain their own low-pass crossover, the PSW108 will
handle the low-pass filtering. If the receiver's subwoofer output or "LFE" output has a built-in low-pass filter, the PSW108's lowpass control should be turned fully clockwise (160Hz).
Note: The PSW108 does not have a dedicated LFE input.
Speaker Level Input/Output: The subwoofer has spring clips for the speaker level inputs and outputs. The subwoofer's lowpass filter sends bass frequencies (based on the setting of the filter) to the subwoofer. The speaker level inputs and outputs
are shorted together, so the output is not crossed over. You should set you receiver's front speaker setting to Large.
