Placement:
The placement of your subwoofer can significantly impact its performance. Experiment with different locations to find the best sound for your room.
- Corner Placement: Placing the subwoofer in a corner can maximize its output and impact.
- Near Front Speakers: Placing it near your main front speakers can create a more seamless soundstage.
- Avoid Enclosures: Do not place the subwoofer in an enclosed cabinet, as this can restrict airflow and affect sound quality.

Connecting Your Subwoofer:
The PSW111 offers flexible connection options to integrate with various home audio systems.
- LFE Input: For receivers with a dedicated LFE (Low-Frequency Effects) output, connect a single RCA cable from the receiver's LFE output to the subwoofer's LFE input.
- Line-Level Inputs: For receivers without an LFE output, connect RCA cables from the receiver's stereo pre-out (Left/Right) to the subwoofer's Line In (Left/Right) inputs.
- Speaker-Level Inputs/Outputs: For receivers without line-level outputs, connect speaker wires from your receiver's main speaker outputs to the subwoofer's speaker-level inputs, then connect speaker wires from the subwoofer's speaker-level outputs to your main speakers.

4. Operating
Controls:
The PSW111 features several controls on its rear panel for fine-tuning its performance:
- Volume Control: Adjusts the 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.
- Phase Toggle Switch (0°/180°): Adjusts the phase of the subwoofer output relative to your main speakers. Experiment with both settings to find the one that provides the most impactful and coherent bass.
- 3-Way Power Switch (On/Auto/Off):
- On: The subwoofer remains continuously on.
- Auto: The subwoofer automatically turns on when it detects an audio signal and enters standby mode after a period of inactivity.
- Off: The subwoofer is powered off.
Integration with Other Speakers:
The PSW111 is timbre-matched to seamlessly blend with other Polk Audio speakers, such as those from the TSI, RM, and R/T/M Series, ensuring a cohesive and balanced sound experience.

5. Maintenance
Proper care will ensure the longevity and optimal performance of your subwoofer.
- Cleaning the Cabinet: Use a soft, dry cloth to wipe the cabinet. For stubborn marks, lightly dampen the cloth with water or a mild, non-abrasive cleaner. Avoid harsh chemicals.
- Grille Care: The detachable grille can be gently vacuumed to remove dust.
- Environmental Conditions: Avoid exposing the subwoofer to extreme temperatures, humidity, or direct sunlight.
6. Troubleshooting
If you encounter issues with your PSW111 subwoofer, refer to the following common problems and solutions:
