Setup
1. Placement
The RP-1200SW features a front-firing driver, allowing for flexible placement within your room. Experiment with different locations to achieve optimal bass response.

2. Connections
The RP-1200SW offers multiple connection options:
- LFE Input: Connect a single RCA cable from your receiver's LFE output to the subwoofer's LFE input for dedicated low-frequency effects.
- Stereo RCA Inputs: For receivers without an LFE output, connect stereo RCA cables from your receiver's pre-out (subwoofer or main) to the subwoofer's left and right RCA inputs.
- WA-2 Wireless Port: For wireless connectivity, connect an optional Klipsch WA-2 Wireless Subwoofer Kit (sold separately) to the WA-2 port. This allows for flexible placement without audio cables.
Both RCA and wireless inputs can be used simultaneously, enabling connection to multiple systems if desired.

3. Initial Configuration
After connecting, adjust the subwoofer's settings to integrate it seamlessly with your main speakers and room acoustics. Use the controls on the rear panel:
- Low-Pass Crossover: This control determines the highest frequency the subwoofer will reproduce. Adjust it to blend smoothly with your main speakers. A common starting point is 80Hz, but it may vary based on your main speakers' low-frequency capabilities.
- Phase: The phase control (0° or 180°) helps ensure the subwoofer's output is in sync with your main speakers. Listen for the most impactful and coherent bass response.
- Gain (Volume): Adjust the gain to match the output level of your main speakers. Start with a low setting and gradually increase until the bass is balanced and not overpowering.

Operating
Once set up, the subwoofer operates automatically with your audio system. It features a 1/2-watt standby mode for energy efficiency, activating when an audio signal is detected and entering standby when no signal is present for a period.
Power On/Off
Connect the subwoofer to a power outlet using the provided power cord. The subwoofer will typically power on automatically when an audio signal is received. To manually power off, use the power switch located on the rear panel.
Adjusting Sound
Minor adjustments to the Low-Pass, Phase, and Gain controls can be made as needed to suit different audio content or listening preferences. Always make small adjustments and listen to the effect before making further changes.
Maintenance
To ensure the longevity and optimal performance of your Klipsch RP-1200SW subwoofer, follow these maintenance guidelines:
