Driver: The Polk Audio PSW125 uses a 12" 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 listening levels.
Motor Structure: The PSW125 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 150 watts RMS/300 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 PSW125 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 PSW125 is available in a Black or Cherry finish.
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 its loudness.
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 PSW125 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 PSW125 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 PSW125 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 jack.
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.
