Description

Soundlight Series Heard, Not Seen

The KEF Ci100.2QR is part of KEF’s acclaimed Soundlight Series, a breakthrough in ultra‑compact architectural audio designed to blend seamlessly into modern interiors. Purpose‑built for flush mounting into ceilings and walls, the Ci100.2QR matches the size and appearance of standard downlights, delivering true KEF sound from a speaker so small it virtually disappears.

Despite its tiny footprint, the Ci100.2QR delivers astonishing performance, thanks to KEF’s patented Uni‑Q driver array. By placing the tweeter at the acoustic center of the midrange cone, Uni‑Q acts as a single point source, providing exceptionally wide dispersion. This ensures smooth, even sound coverage throughout the room no narrow sweet spot, no uneven response, just clean, natural audio everywhere.

Designed for discreet distributed audio, hospitality spaces, luxury residences, and architectural environments where aesthetics are paramount, the Ci100.2QR offers high‑quality sound in places traditional speakers cannot fit. Its ultra‑slim profile and paintable grille allow it to blend effortlessly with halogen lighting fixtures and modern ceiling designs.

Compact, elegant, and surprisingly powerful, the Ci100.2QR is the perfect solution when you need KEF performance in the smallest possible form factor.
