3.3 Wiring
Before connecting, ensure all power to your audio system is turned off.
- Run appropriate gauge speaker wire from your amplifier/receiver to the wall opening.
- Strip approximately 1/2 inch of insulation from the ends of the speaker wires.
- Connect the positive (+) terminal of the speaker (red) to the positive (+) output of your amplifier.
- Connect the negative (-) terminal of the speaker (black) to the negative (-) output of your amplifier.
- Ensure all connections are secure and free from stray wire strands that could cause short circuits.
3.4 Speaker Installation
- Carefully insert the speaker into the prepared wall opening.
- Tighten the six dog-leg installation points (usually screws on the front baffle) until the speaker is firmly secured to the wall. Do not overtighten.
- Attach the magnetic grille to the speaker baffle.
4. Operation
Once installed and wired, your KLH Faraday Series M-8600-W speakers are ready for use.
- Ensure your amplifier/receiver is powered on and set to the correct input source.
- Start with the volume at a low level and gradually increase it to your desired listening level.
- The recommended amplifier power for these speakers ranges from 50W to 275W. Operating within this range will ensure optimal performance and longevity.
5. Maintenance
The KLH Faraday Series M-8600-W speakers require minimal maintenance.
- Cleaning: Dust the grilles and speaker frames periodically with a soft, dry cloth. For stubborn marks, a slightly damp cloth can be used, but avoid excessive moisture. Do not use harsh chemicals or abrasive cleaners.
- Grilles: The grilles are magnetic and can be easily removed for cleaning or inspection. Handle them carefully to avoid bending.
- Environment: Ensure the speakers are not exposed to extreme temperatures, direct sunlight, or high humidity, which can affect performance and lifespan.
6. Troubleshooting
If you experience issues with your speakers, refer to the following common troubleshooting steps:
- No Sound:
- Check all speaker wire connections at both the speaker and the amplifier/receiver. Ensure they are secure and correctly polarized (+ to +, - to -).
- Verify that the amplifier/receiver is powered on and set to the correct input source.
- Test with another audio source or speaker if possible to isolate the problem.
- Distorted Sound:
- Reduce the volume level on your amplifier/receiver. Overdriving the speakers can cause distortion.
- Check speaker wire connections for loose strands or short circuits.
- Ensure the amplifier's power output is within the recommended range (50W-275W) for the speakers.
- Inspect the speaker cones and tweeters for any visible damage.
- Uneven Sound or One Speaker Not Working:
- Check the balance settings on your amplifier/receiver.
- Verify the wiring for the affected speaker.
- Swap the speaker wires at the amplifier for the left and right channels to determine if the issue follows the speaker or the amplifier channel.
