KEF Ci Series 6.5" In-Ceiling Speakers-Ci160CSds
KEF Ci Series 6.5" In-Ceiling Speakers with asymmetrical tweeter island and double .75" tangerine waveguides that recreate stereo


The Ci Series combines advanced audio technologies, brilliantly innovative engineering and superlative design. Each model is engineered to attain the ultimate performance in its specific setting, and integrates perfectly with other KEF speakers.


  • The KEF Ci Series Ci160CSds is a high-fidelity flush-mount speaker that recreates stereo, and is ideal for locations where there is only room for one speaker. Thanks to KEF’s simple and ingenious screw down clamping system – with moisture-resistant fixings – you can place these speakers in environments such as bathrooms or under eaves.

Ultra Thin Bezel (UTB)

  • KEF’s search for the definitive discreet Ci speaker has culminated in the new Ultra Thin Bezel designs, offering the slimmest possible visible rim around the speaker.

Asymmetrical Tweeter Island

  • Delivering a cleaner, purer sound to the maximum number of listeners, the tweeter island reduces diffraction and enhances off-axis, high frequency response.

Fast And Easy To Install

  • KEF’s Ci loudspeaker design makes them so quick and easy to install that once the wire is run and the hole is cut in your wall or ceiling you can be listening to music in less than two minutes.

Tangerine Waveguide

  • The ‘tangerine’ waveguide has exceptionally wide dispersion characteristics, and provides excellent driver protection.

Forward Woofer Mounting

  • Forward woofer mounting is another KEF technology that eliminates diffraction and ensures we create speakers that perform brilliantly regardless of placement.

Computer Optimized Trim Ring

  • The new, computer optimized trim ring offers stunning midrange clarity and a more open and natural sound across a wider area.

Special Grille Treatments

  • Ci UTB speakers feature a powder-coated grille treated with a proprietary process, which combined with the moisture-resistant fixings and other rugged materials we use, makes the speaker corrosion resistant so it’s ideal for use in humid and salt spray conditions, such as bathrooms, near pools, beside the ocean, or even on your yacht.

Complete Magnetic Circuit

  • This feature was designed to hold the speaker grille firmly in place.

New Mounting Leg

  • The new mounting leg is easy to use and distributes force evenly, benefiting fast installation without damage to the wall or ceiling.

Bayonet Shaped PCB

  • This adds rigidity to the speaker and protects the crossover. Grilles can be installed easily, even in uneven ceilings.
