KEF’s First THX® Certified Dominus In‑Wall Speaker

The Ci5160REFM‑THX represents the pinnacle of KEF’s architectural engineering — the first in‑wall loudspeaker to achieve THX® Certified Dominus, the highest and most demanding performance class in the THX® system. Designed for large home theatres and expansive living spaces, it delivers breathtaking realism, precision, and scale while remaining visually discreet.

Powered by KEF’s latest 12th‑generation Uni‑Q® driver array with MAT™, this reference‑grade in‑wall speaker produces an immersive soundstage with exceptional clarity and detail.

Realistic, High‑Fidelity Sound

The Ci5160REFM‑THX features four 160mm (6.5‑inch) bass drivers engineered specifically for in‑wall performance. The result is:

  • Deep, articulate bass down to 32Hz

  • Clean, controlled low‑frequency extension

  • A massive, vented motor system for effortless dynamics

  • A seamless, room‑filling soundstage

This is architectural audio without compromise.
