Overview

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.

Features

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.
