Quick Answer
To install KEF Ci160QS or Ci130QS in-wall speakers, you'll need to cut a precise hole, run speaker wire, connect the terminals, and secure the speaker with its clamping system. Follow the steps below to ensure a clean, secure installation.
Why Choose KEF Architectural Speakers?
KEF's architectural speakers, including the Ci160QS and Ci130QS, are designed to blend seamlessly into your walls or ceiling. Their ultra-thin bezels and narrow rims allow for a clean, minimalist look that doesn't compromise on sound quality.
Both models feature KEF's patented Uni-Q driver array, which spreads sound over a wider area. This means you can use fewer speakers to achieve an even soundstage, making them a practical choice for multi-room audio or home theater setups.
Tools and Materials You'll Need
Before you start, gather the following: a stud finder, a pencil, a level, a drywall saw or keyhole saw, speaker wire, wire strippers, a screwdriver, and a drill (if needed for pilot holes). Having everything ready will make the installation smoother.
You'll also need the included template or the speaker itself to mark the cutout. If you're unsure about the exact dimensions, refer to the product manual or measure the speaker's mounting flange.
Step-by-Step Installation Guide
- Choose the Location: Use a stud finder to locate wall studs and avoid them. Mark the desired position, ensuring there are no obstructions like pipes or electrical wiring behind the wall. Hold the template (or the speaker) against the wall and trace the outline with a pencil. Always double-check for studs before cutting; cutting into a stud can damage the speaker and the wall.
- Cut the Hole: Using a drywall saw, carefully cut along the traced line. Start with a small pilot hole to insert the saw, then follow the outline. Keep the saw at a low angle to avoid damaging the surrounding drywall. Cut slightly inside the line if you're unsure; you can always enlarge the hole, but you can't shrink it.
- Run the Speaker Wire: Route the speaker wire from your amplifier or receiver to the cutout hole. Leave at least 12 inches of slack to make connections easier. If you're running wire through walls, use plenum-rated wire for safety. Label the wire ends (left/right) to avoid confusion during connection.
- Connect the Wire to the Speaker: Strip about 1/2 inch of insulation from the wire ends. Connect the positive terminal (usually red) to the positive wire and the negative terminal (black) to the negative wire. Many KEF speakers have spring-loaded terminals; press to open, insert the wire, and release. Ensure no stray wire strands touch the opposite terminal to avoid a short circuit.
- Mount the Speaker: Insert the speaker into the hole, aligning it properly. Tighten the screws (or use the clamping system) to secure the speaker to the drywall. Be careful not to overtighten, as this can damage the drywall or the speaker frame. Use a level to ensure the speaker is straight before tightening fully.
- Test and Fine-Tune: Turn on your system and play audio to test the speaker. If the sound is unbalanced, check the wire connections and polarity. Some KEF models have a switch for treble or boundary compensation; adjust as needed for your room. If the speaker sounds 'off,' re-check the polarity; reversed polarity can cause weak bass and poor imaging.
