KEF CL200RS-THX Architectural Speakers

Extreme Home Theatre Performance with KEF’s Reference‑Level Engineering

The KEF Ci200RS‑THX is a flagship in‑wall loudspeaker engineered for Extreme Home Theatre environments where uncompromised dynamics, clarity, and cinematic accuracy are essential. As part of the Ci‑R Series, it inherits acoustic DNA from KEF’s legendary Reference Series, bringing studio‑grade performance into a discreet architectural form factor.

At the heart of the Ci200RS‑THX is a powerful 38 mm (1.5 in.) vented aluminium dome tweeter with KEF’s signature Tangerine Waveguide, delivering exceptional high‑frequency dispersion and detail. This is paired with a massive‑magnet 200 mm (8 in.) woofer featuring KEF’s Z‑Flex surround, enabling deep, controlled bass and effortless dynamics even at high output levels.

Certified to THX Ultra, the Ci200RS‑THX meets the rigorous standards required to reproduce the tonal balance, impact, and emotional intensity of the filmmaker’s final mix. Whether used in 2.1, 5.1, 7.1, or advanced immersive configurations, it delivers the high output, wide dispersion, and precise imaging expected from a professional cinema‑grade loudspeaker.

Designed to blend seamlessly into any interior, the Ci200RS‑THX combines KEF’s Ultra‑Thin Bezel (UTB) aesthetics with the robust engineering required for large‑room home theatres. It offers the best of both worlds: the power of a traditional high‑end box speaker with the elegance and integration of an architectural solution.

For large rooms, luxury cinemas, and high‑performance media spaces, the Ci200RS‑THX stands as one of KEF’s most capable in‑wall loudspeakers—delivering a magical, emotionally engaging theatre experience that fills even the biggest spaces with precision and authority.
