5. Setup and Connections

5.1 Placement

For optimal performance, place the subwoofer in a corner of the room or along a wall. Experiment with different placements to find the best bass response for your listening environment. Ensure adequate ventilation around the unit.

5.2 Connecting Your Subwoofer

The HTS 10 offers two primary connection methods:

• LFE (Low-Frequency Effects) Input: Connect a single RCA cable from your AV receiver's LFE or Subwoofer Pre-Out to the LFE input on the subwoofer. This is the recommended connection for home theater systems as it allows the receiver to manage bass management.
• Stereo Line Level Inputs: For receivers without an LFE output, connect stereo RCA cables from your receiver's Front Left and Right Pre-Outs to the Line In (Left/Right) inputs on the subwoofer.

After connecting, plug the power cord into the subwoofer and then into a wall outlet.

6. Operating Your Subwoofer

6.1 Power Control

The subwoofer features a power toggle switch with an "Auto" setting. When set to "Auto," the subwoofer will automatically turn on when it detects an audio signal and enter standby mode after a period of inactivity. This provides convenient power management.

6.2 Adjusting Settings

The rear panel controls allow for fine-tuning of the subwoofer's output:

• Volume: Adjusts the overall output level of the subwoofer. Start with a moderate level and adjust to blend with your main speakers.
• Low Pass Filter: Controls the upper frequency limit of the subwoofer. If using an AV receiver with bass management, set this to its highest setting (LFE/Bypass). If using stereo line level inputs, adjust this to blend smoothly with your main speakers' low-frequency cutoff.
• Phase: A toggle switch (0° or 180°) that helps blend the subwoofer's output with your main speakers. Experiment with both settings to find which provides the most cohesive and impactful bass in your listening position.

7. Maintenance

To ensure the longevity and optimal performance of your Polk Audio HTS 10 Subwoofer, follow these maintenance guidelines:

• Cleaning: Use a soft, dry cloth to clean the cabinet. Avoid using harsh chemicals, cleaning sprays, or abrasive materials, as they may damage the finish.
• Ventilation: Ensure that the subwoofer's vents are not obstructed to prevent overheating. Do not place the subwoofer in an enclosed cabinet without proper airflow.
• Placement: Avoid placing the subwoofer in direct sunlight, near heat sources, or in areas with high humidity.
