3. Setup

3.1 Unpacking

Carefully remove the PSW110 subwoofer from its packaging. Inspect the unit for any signs of damage during transit. If damage is present, contact your dealer immediately.

3.2 Placement

The placement of your subwoofer significantly impacts its performance. Experiment with different locations to find the best sound for your room.

• Corner Placement: Placing the subwoofer in a corner often maximizes its output and impact.
• Near Main Speakers: Placing the subwoofer near your front main speakers can improve blending and create a more cohesive soundstage.
• Stable Surface: Always place the subwoofer on a stable, level surface to prevent vibrations and ensure proper operation.
• Ventilation: Ensure there is adequate space around the subwoofer for proper ventilation. Do not place it in an enclosed cabinet without airflow.

3.3 Connections

The PSW110 offers multiple connection options to integrate with various home audio systems. Refer to the rear panel diagram below for connection points.

• LFE Input (Recommended): If your AV receiver or processor has a dedicated 'Subwoofer Out' or 'LFE Out' jack, connect a single RCA cable from this output to the LFE input on the PSW110. This is the simplest and often best connection method.
• Line-Level Inputs: If your receiver does not have an LFE output but has stereo pre-amp outputs (e.g., 'Front Pre-Out'), connect RCA cables from these outputs to the 'LINE IN' (Left and Right) inputs on the PSW110.
• Speaker-Level Inputs/Outputs: If your receiver does not have any pre-amp outputs, you can use the speaker-level connections. Connect the speaker wires from your receiver's front left and right speaker outputs to the 'SPEAKER IN' terminals on the PSW110. Then, connect speaker wires from the 'SPEAKER OUT' terminals on the PSW110 to your front left and right speakers. Ensure correct polarity (+ to + and - to -).
• Power Connection: Once all audio connections are made, plug the subwoofer's power cord into a suitable AC outlet.

4. Operating Your Subwoofer

4.1 Rear Panel Controls

The rear panel of the PSW110 features several controls to fine-tune its performance and integrate it seamlessly with your main speakers.

• VOLUME: This knob controls the overall output level of the subwoofer. Adjust it to achieve the desired bass intensity relative to your main speakers.
• LOW-PASS CROSSOVER: This knob sets the upper frequency limit at which the subwoofer will operate. Frequencies above this setting will be rolled off. Adjust this to blend the subwoofer's bass output smoothly with the low-frequency capabilities of your main speakers. A common starting point is around 80Hz-100Hz, but it may vary depending on your main speakers.
• PHASE (0°/180°): This switch adjusts the phase of the subwoofer's output relative to your main speakers. Experiment with both 0° and 180° settings. The correct setting will result in the most impactful and cohesive bass response.
• POWER MODE (ON/AUTO/OFF):
  • ON: The subwoofer will remain powered on continuously.
  • AUTO: The subwoofer will automatically turn on when it detects an audio signal and enter a low-power standby mode after a period of inactivity (typically 15-20 minutes) without a signal.
  • OFF: The subwoofer is completely powered off.

4.2 Blending the Subwoofer

Achieving a seamless blend between your subwoofer and main speakers is crucial for optimal sound. Adjust the VOLUME and LOW-PASS CROSSOVER controls while listening to various types of audio content. The goal is for the subwoofer to enhance the bass without drawing attention to itself as a separate sound source.

5. Maintenance

The Polk Audio PSW110 subwoofer requires minimal maintenance to ensure long-lasting performance.

• Cleaning: Wipe the cabinet with a soft, dry, lint-free cloth. Do not use harsh chemicals, cleaning sprays, or abrasive materials, as these can damage the finish.
• Ventilation: Periodically check that the ventilation openings on the rear panel are clear of dust and debris to prevent overheating.
• Placement: Ensure the subwoofer remains on a stable surface and is not exposed to extreme temperatures, direct sunlight, or excessive moisture.
