Features KEF’s patented Uni-Q driver array

Ci4100QL-THX is a THX Certified Select in-wall speaker. A deep understanding of the filmmaking process and surround sound is at the very heart of every THX certified 2.1, 5.1 and 7.1 speaker system.

Ci4100QL-THX

Featuring KEF’s sophisticated ’sit anywhere’ Uni-Q driver array, which places the tweeter in the acoustic centre of the bass/midrange cone, this allows both the tweeter and woofer to act as a single point source that disperses the sound widely and evenly throughout the room. Together with the discreet Ultra Thin Bezel (UTB) design, offering the slimmest possible visible rim around the speaker, the Ci-Q Series range gives you tremendous freedom to position the speakers where you please.

Engineered with design characteristics of professional studio speakers, THX recreates the tonal balance of the filmmaker's final mix in your living room. The results? Action sequences are impactful, and dialogue-driven moments are natural and engaging.

Crisp Quality

I’ve bought these in advance of rearranging the lounge. Future state is flushed into the wall, but current state is mounted in some gorgeous oak boxes a mate has made. The oak gives the speakers a wonderful depth to the sound and the clarity is exceptional. He’s making me a third for the centre. Can’t wait to have all 5 firing away and adding some additional Kef’s into the ceiling.

KEF Ci4100QL-THX.

The speaker brilliant I currently have one as the centre channel for a 5.1 set up and the audio really stands out compared to the Bose speakers.

Can’t wait to finish the setup with more THX SPEAKERS 👌🏻
