4. Installation and Setup
4.1 Placement Considerations
Optimal speaker placement is crucial for sound quality. For LCR applications, position the speakers at ear level when seated, equidistant from the primary listening position. For surround sound, place them to the sides or slightly behind the listening area, also at ear level or slightly above.

4.2 Mounting the Speaker
The KEF Q4 Meta is designed for on-wall mounting. Ensure the mounting surface is structurally sound and can support the speaker's weight. Use appropriate wall anchors and screws (not included) for secure installation. Refer to the included mounting template (if provided) for precise hole placement.
4.3 Connecting to Your Audio System
Connect the speaker to your amplifier or AV receiver using high-quality speaker wire. Observe correct polarity: connect the positive (+) terminal on the speaker to the positive (+) terminal on your amplifier, and the negative (-) terminal on the speaker to the negative (-) terminal on your amplifier. Incorrect polarity can affect sound imaging and bass response.

5. Operation
5.1 Initial Power On
Once connected, power on your amplifier or receiver. Start with the volume at a low level and gradually increase it to your desired listening level. Ensure all connections are secure if no sound is produced.
5.2 Audio Playback
The KEF Q4 Meta speakers are passive and require an external amplifier. Select your desired audio source on your amplifier/receiver and enjoy the sound. For optimal performance, ensure your amplifier's power output matches the speaker's recommended power handling.
6. Care and Maintenance

- Placement: Avoid placing speakers in direct sunlight or near heat sources.
- Handling: Always handle the speaker with care, especially the driver cones.
