Setup
1. Placement
Optimal subwoofer placement is crucial for sound quality. Experiment with different locations in your room to find the best balance of bass response. Generally, placing the subwoofer in a corner can enhance bass output, while placing it closer to your main speakers can improve integration. Avoid placing it directly against a wall if it causes excessive booming.
2. Connections
The PSW10 offers flexible connection options:
- Line-Level Input (RCA): Connect your receiver's subwoofer output (LFE or Sub Out) to the LFE input on the subwoofer using an RCA cable. If your receiver has left and right pre-out jacks, use both left and right line-level inputs on the subwoofer.
- Speaker-Level Inputs/Outputs: For receivers without a dedicated subwoofer output, connect the speaker-level outputs from your receiver to the speaker-level inputs on the subwoofer. Then, connect the speaker-level outputs from the subwoofer to your main left and right speakers.

Operating Instructions
Once connected, adjust the following controls on the rear panel (refer to Figure 2):
- Volume Control: Adjusts the overall output level of the subwoofer. Start with a low setting and gradually increase until the bass blends seamlessly with your main speakers.
- Low-Pass Filter: This control sets the upper frequency limit for the subwoofer. Adjust it to match the low-frequency capabilities of your main speakers. A common starting point is 80 Hz.
- Phase Toggle Switch (0°/180°): Adjust this switch to achieve the best bass impact and blend with your main speakers. Listen to music or a movie scene with strong bass and switch between 0° and 180° to determine which setting provides the most coherent and impactful bass.
- 3-Way Power Switch (Auto/On/Off):
- Auto: The subwoofer will automatically turn on when it detects an audio signal and enter standby mode after a period of inactivity.
- On: The subwoofer remains continuously powered on.
- Off: The subwoofer is powered off.
Maintenance
To ensure the longevity and optimal performance of your Polk Audio PSW10 subwoofer, follow these maintenance guidelines:
- Cleaning: Use a soft, dry cloth to wipe down the cabinet. Avoid using harsh chemicals, solvents, or abrasive cleaners, as these can damage the finish.
- Placement: Keep the subwoofer away from direct sunlight, heat sources, and excessive moisture. Ensure adequate ventilation around the amplifier panel to prevent overheating.
- Power: Disconnect the power cable from the wall outlet if the subwoofer will not be used for an extended period.
Troubleshooting
| Problem | Possible Solution |
|---|---|
| No sound from subwoofer | Check power connection and ensure the 3-way power switch is set to 'On' or 'Auto'. Verify audio cable connections from the receiver to the subwoofer. Increase the volume control on the subwoofer. |
| Weak or distorted bass | Adjust the volume control and low-pass filter. Experiment with the phase toggle switch (0°/180°). Check for proper placement and ensure no obstructions are blocking the woofer or port. |
| Subwoofer hums | Ensure all connections are secure. Try plugging the subwoofer into a different electrical outlet. If using line-level inputs, try a ground loop isolator. |
| Subwoofer does not turn on automatically | Ensure the 3-way power switch is set to 'Auto'. Increase the volume output from your receiver's subwoofer channel to ensure a strong enough signal for auto-on detection. |
