KEF’s first THX® Certified Dominus speaker
The in-wall Ci-Reference architectural speaker Ci5160REFM-THX is KEF's first in-wall speaker to be THX® Certified Dominus among the very few that can achieve this ultimate standard worldwide. Together with a 12th generation Uni-Q driver array with Metamaterial Absorption Technology (MAT™), Ci5160REFM-THX delivers an immersive, high-fidelity soundstage with unmatched sonic excellence even for the most extensive home theatres and living rooms.

Realistic, high-fidelity sound
Featuring four 160mm (6.5in.) bass drivers, Ci5160REFM-THX delivers a clean, rich and highly articulate bass response down to 32Hz. Together with the massive, vented motor system that was designed specifically for an in-wall environment, making Ci5160REFM-THX disappear into the room to leave an awe-inspiring, immersive experience.

  • THX® Certified Dominus
    Ci5160REFM-THX is THX® Certified Dominus – the largest and most powerful THX® performance class, which is the closest approximation to a public cinema experience that one can achieve at home.
  • Metamaterial Absorption Technology
    Absorbs 99% of the unwanted sound.
  • Handcrafted in UK
    As all KEF high-end speakers, the Ci-Reference series is designed, engineered, and hand-built in Maidstone, UK.
  • Uni-Q®
    Acts as a single point source to enlarge the 'sweet spot' and disperse sound more evenly.
  • Finished to perfection
    Available in Aluminium Black/Grey, a hairline finished aluminium baffle in black, with the Uni-Q driver array in grey.
  • Hide your speakers, not your sound
    The paintable magnetic metal grille and optional black cloth grille ensure the speaker seamlessly blends into the environment.
  • Total attention to detail
    The 11mm thick precision-machined aluminium baffle is engineered to eliminate vibration and provides a stoic platform for the powerful drivers to perform at their best.
