KEF Ci100QS Square Architectural Speaker

KEF Ci100QS Square Architectural Speaker

The KEF Ci100QS architectural speaker is designed for permanent installation where audio equipment needs to integrate with the room's surfaces. Its square front profile provides a defined visible outline, while the main speaker assembly fits behind the mounting surface. This arrangement allows the sound system to become part of the interior layout without occupying furniture or floor space.

The driver configuration combines a 100 mm low-frequency unit with a 19 mm high-frequency unit. The specified open-backed frequency response is 80 Hz–27 kHz at a ±6 dB tolerance, with a crossover frequency of 3 kHz. A nominal impedance of 4 ohms and sensitivity of 88 dB at 2.83V/1m provide useful reference points for matching the speaker to the intended amplification. Recommended amplifier power is 10–50W.

The Uni-Q array places the tweeter at the centre of the bass driver, helping the two frequency ranges radiate from closely aligned positions. The compact Soundlight format suits installations where a small visible speaker is important. A 127 mm square front and shallow mounting requirement make the model useful when planning sound alongside other compact ceiling or wall fittings.

The external dimensions are 127 × 127 × 76 mm, with a required cut-out of 112 × 112 mm. Mounting depth from the finished surface is 72 mm, so the available cavity space should be considered alongside the visible opening. These dimensions distinguish the complete speaker assembly from the opening needed to install it. A net weight of 0.67 kg completes the mechanical specification, helping the installation plan account for the speaker's physical requirements as well as its acoustic role.
