Driver: The Polk Audio PSW110 uses a 10" Dynamic Balance
composite cone driver for deep, accurate response with low distortion. For a
smoother response and improved durability, the woofer utilizes a rubber surround.
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
Motor Structure: The PSW110 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 100 watts RMS/200 watts dynamic power that supplies clean power for loud
bass and a wide dynamic range necessary to recreate a life-like experience in your
Enclosure: The PSW110 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 PSW110 is available in a Black or
Down-Firing Port: The powered subwoofer's downward 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
3-Way Power Switch: The subwoofer has a 3-way power switch on
the rear panel. You can select Auto, which turns the unit on automatically when
an input signal is received and off 15 minutes after the signal stops; On, which
keeps the unit on and Standby, which turns the unit off. The LED power indicator
glows green when the unit is on and red when the unit is off.
Volume Control: The PSW110 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 PSW110 offers a continuously variable
low-pass filter, adjustable from 60-160 Hz. There is an LFE position for use
with the filtered LFE output from a receiver or preamp.
Line Inputs: The subwoofer has gold plated left and right
RCA line level inputs for use with receivers having subwoofer or stereo preamp
outputs that do not contain their own low-pass crossover. Using the Line Inputs
allows PSW110 to do all the low-pass filtering. If your receiver or processor
only has a single subwoofer line output, connect it to the Right line input
LFE In: The right channel RCA input doubles as the LFE
input; if your receiver has an LFE output and a built-in crossover, use this
input and set the low-pass filter dial to LFE.
Speaker Level Input/Output: The subwoofer has spring clips
for the speaker level inputs and outputs. The subwoofer's low-pass 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.
