3. Setup
3.1. Subwoofer Placement
Optimal placement of the ES10 subwoofer is crucial for balanced sound. Consider the following:
- Corner Placement: Placing the subwoofer in a corner often maximizes its output and impact.
- Front of Room: Positioning the subwoofer near your front speakers can create a more cohesive soundstage.
- Listening Position: Experiment with placing the subwoofer at your primary listening position, then moving around the room to find where the bass sounds most balanced.
- Proximity to Walls: The front-firing design and dual Power Ports allow for flexible placement, including close to walls or inside cabinets, without significant air noise or distortion.

3.2. Connecting the Subwoofer
The ES10 subwoofer offers flexible connectivity options for various audio systems.
- LFE (Low-Frequency Effects) Input: For receivers with a dedicated subwoofer output (LFE or Sub Out), connect a single RCA cable from the receiver's subwoofer output to the ES10's LFE input. This is the recommended connection for home theater systems.
- Line-Level Inputs (Left/Right): If your receiver does not have an LFE output, connect RCA cables from your receiver's pre-out (or stereo output) to the ES10's Left and Right line-level inputs.

3.3. Power Connection
Once audio connections are made, connect the supplied power cable to the subwoofer's power inlet and then to a suitable AC wall outlet. The subwoofer features an auto-sensing power supply.
4. Operation
4.1. Power Management
The ES10 subwoofer includes an auto-sensing power supply. When the subwoofer detects an audio signal, it will automatically power on. When no audio signal is detected for a period, it will switch to standby mode to conserve energy. This feature ensures the subwoofer is ready when needed and efficient when not in use.
4.2. Adjusting Controls
The rear panel of the ES10 subwoofer provides controls for fine-tuning its performance to match your room and main speakers.

- Volume Control: Adjusts the overall output level of the subwoofer. Start with a moderate setting and adjust to blend with your main speakers.
- Low Pass Filter: This control sets the upper frequency limit for the subwoofer. Adjust it to ensure a smooth transition between the subwoofer and your main speakers. A common starting point is around 80-100 Hz, but this may vary based on your main speakers' low-frequency capabilities.
- Phase Control (Time-Smart Phase Control): This feature allows for 360-degree phase adjustment. It helps to align the subwoofer's output with your main speakers, preventing cancellation or reinforcement of bass frequencies at the crossover point. Adjust this control while listening from your primary position until the bass sounds most impactful and cohesive.
5. Care and Maintenance
To maintain the appearance and performance of your Polk Audio ES10 Subwoofer, follow these guidelines:
- Cleaning: Use a soft, dry cloth to wipe the cabinet. Avoid abrasive cleaners, solvents, or strong detergents, as they may damage the finish.
- Grille Care: The removable grille can be gently cleaned with a soft brush or vacuum cleaner attachment.
- Placement Environment: Avoid placing the subwoofer in direct sunlight, near heat sources, or in areas with high humidity. Ensure adequate ventilation around the unit.
- Handling: When moving the subwoofer, lift it carefully from the base. Avoid dropping or subjecting it to strong impacts.
6. Troubleshooting
