Placement
The placement of your subwoofer significantly impacts its sound performance. Experiment with different locations to find the best bass response in your listening environment. Common placements include:
- Corner Placement: Placing the subwoofer in a corner can maximize its output and provide a more impactful bass.
- Front of the Room: Positioning the subwoofer near your front speakers can create a more seamless soundstage.

Connections
Connect your subwoofer to your audio receiver or amplifier using the appropriate inputs:
- LFE Input: For receivers with a dedicated Subwoofer/LFE output, connect a single RCA cable from the receiver's LFE output to the subwoofer's LFE input. This is the recommended connection for most home theater systems.
- Line Level Inputs (Left/Right): If your receiver does not have an LFE output, connect RCA cables from your receiver's stereo pre-out (left and right) to the subwoofer's Line Level inputs.
Once connected, plug the subwoofer's power cable into a wall outlet.
Operating Controls
The Klipsch R-12SW features several controls on its rear panel to fine-tune its performance to your listening preferences and room acoustics.
Rear Panel Controls
- Gain (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 without overpowering them.
- Low Pass Crossover Control: Determines the highest frequency the subwoofer will reproduce. Adjust this to match the low-frequency capabilities of your main speakers. A common starting point is 80 Hz, but you may need to adjust it based on your speaker size and room.
- Phase Control (0°/180°): This switch helps to match the subwoofer's output phase with your main speakers. Experiment with both settings to find the one that provides the most impactful and coherent bass.
- Power Mode (On/Auto/Off):
- ON: The subwoofer remains continuously powered 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.
Maintenance
To ensure the longevity and optimal performance of your Klipsch R-12SW subwoofer, follow these simple maintenance guidelines:
- Cleaning: Use a dry, soft cloth to clean the cabinet. Avoid using abrasive cleaners, solvents, or strong detergents.
- Placement Environment: Keep the subwoofer away from direct sunlight, heat sources, and excessive moisture. Ensure adequate ventilation around the unit.
- Dusting: Regularly dust the woofer cone and cabinet to prevent buildup that could affect sound quality.
Troubleshooting
If you encounter any issues with your Klipsch R-12SW subwoofer, refer to the following common troubleshooting steps:
- No Sound:
- Ensure the subwoofer is plugged into a working power outlet and the power switch is set to ON or AUTO.
- Verify that the audio cables are securely connected to both the subwoofer and your receiver/amplifier.
- Check your receiver's settings to ensure the subwoofer output is enabled and the volume is not muted.
- Distorted or Boomy Sound:
- Adjust the Gain (Volume) control on the subwoofer to a lower setting.
- Adjust the Low Pass Crossover control. A lower setting may reduce boominess.
- Experiment with the Phase control (0°/180°).
- Try repositioning the subwoofer in your room. Moving it away from corners can sometimes help.
- Humming Noise:
- Ensure all audio cables are properly shielded and not running parallel to power cables.
- Try plugging the subwoofer into a different electrical outlet.
- If the hum persists, a ground loop isolator may be necessary.
