• Refined Crossover: Ensures seamless integration of all speaker components for optimal performance.
• Hybrid Aluminum Bass Drivers: Three 6.5-inch drivers provide stiff, piston-like movement for precise and agile bass response.

3. Setup

3.1 Speaker Placement

Optimal speaker placement is crucial for achieving the best sound quality. Consider the following guidelines:

• Stereo Setup: Place the speakers equidistant from your primary listening position, forming an equilateral triangle.
• Distance from Walls: Experiment with placing the speakers away from the front and side walls to minimize bass reflections and improve imaging. A good starting point is 1-3 feet from the rear wall and 2-4 feet from side walls.
• Toe-in: Angle the speakers slightly inward towards the listening position. Adjusting the toe-in can affect the soundstage width and focus.
• Room Acoustics: Soft furnishings, carpets, and curtains can help absorb sound and reduce unwanted reflections.

3.2 Connecting to an Amplifier

The Q11 Meta speakers connect to your amplifier using speaker wire. Ensure your amplifier is turned off before making any connections.

1. Prepare Speaker Wire: Strip approximately 1/2 inch (12mm) of insulation from the ends of your speaker wires. Twist the bare strands tightly.
2. Connect to Speaker: Connect the positive (+) terminal (red) on the speaker to the positive (+) terminal on your amplifier. Connect the negative (-) terminal (black) on the speaker to the negative (-) terminal on your amplifier. Maintain correct polarity for both speakers.
3. Secure Connections: Ensure all connections are tight to prevent signal loss or short circuits.

4. Operating Instructions

4.1 Initial Power-Up

After connecting your speakers, turn on your amplifier and select the appropriate input source. Start with the volume at a low level and gradually increase it.

4.2 Break-in Period

Like many high-fidelity speakers, the KEF Q11 Meta may benefit from a break-in period. This typically involves playing music at moderate volumes for several hours (e.g., 50-100 hours). During this time, the drivers will loosen up, and the sound quality may improve, becoming more open and refined.

4.3 Volume Control and Listening Levels

Always adjust the volume from your amplifier or source component. Avoid excessively high listening levels that can cause distortion or damage to the speakers and your hearing.

5. Maintenance

5.1 Cleaning the Cabinet

Wipe the speaker cabinet with a soft, dry, lint-free cloth. For stubborn marks, a slightly damp cloth can be used, followed immediately by a dry cloth. Avoid abrasive cleaners, solvents, or polishes, as these can damage the finish.

5.2 Cleaning the Drivers and Grilles

The Uni-Q driver and bass drivers should be cleaned gently with a soft brush or a dry, lint-free cloth. Avoid applying pressure to the cones. If your speakers include grilles, they can be carefully removed and dusted. Ensure they are securely reattached after cleaning.

6. Troubleshooting

If you encounter issues with your KEF Q11 Meta speakers, refer to the following common troubleshooting steps:

• No Sound:
  • Check all speaker wire connections at both the speaker and amplifier ends for proper contact and polarity.
  • Ensure the amplifier is powered on and the correct input source is selected.
  • Verify that the volume is not muted or set to a very low level.
• Distorted Sound:
  • Reduce the volume level on your amplifier.
  • Check speaker wire connections for any loose strands that might be causing a short circuit.
  • Ensure your amplifier is not overdriven or clipping.
• Uneven Sound (one speaker louder/softer):
  • Verify that both speakers are connected with correct polarity.
  • Check your amplifier's balance settings.
  • Ensure speakers are placed symmetrically in the room.
• Humming or Buzzing:
  • Ensure all audio cables are securely connected and not running parallel to power cables.
  • Try connecting your audio equipment to a different power outlet or a power conditioner.

If the issue persists after following these steps, consult the KEF support resources or contact customer service.
