Round in-ceiling speaker with 160 mm Uni-Q® driver
The KEF Ci160ER is a round two-way in-ceiling speaker from the Ci-E series, designed to offer reference KEF audio quality at exceptional value, with the same build standards as the British brand's entire architectural range. Sold as a pair, it features a 160 mm (6.5") woofer with a 16 mm (0.6") aluminium dome tweeter in a Uni-Q® configuration, for a frequency response from 52 Hz to 20 kHz. The Ultra-Thin Bezel (UTB) and the paintable magnetic grille ensure discreet visual integration, while the Weather Resistant construction makes it suitable for environments exposed to humidity and UV rays as well, such as bathrooms and kitchens. The optional RIF160R pre-installation frame and the optional RNC160R rear enclosure complete the installation options. The square-format twin of this model is the Ci160ES.
Uni-Q®: uncompromising KEF quality at every listening position
The 160 mm Uni-Q® driver places the 16 mm aluminium dome tweeter exactly at the acoustic centre of the woofer, so that the two act as a single point source. KEF's "sit anywhere" technology eliminates the narrow sweet spot typical of conventional speakers, delivering KEF's renowned sonic clarity to every listener regardless of their position in the room — a fundamental feature for ceiling installations in residential and commercial environments where the listening position cannot be controlled.
Reference performance in a compact round format
With a sensitivity of 89 dB, a response that reaches down to 52 Hz and compatibility with amplifiers from 10 to 100 W into 8 Ω, the Ci160ER offers high-level audio performance for living rooms, bedrooms, home theatre zones and multiroom distribution. With a mounting depth of 85.2 mm and an external diameter of 234.6 mm, it fits comfortably into ceilings where the space available in the cavity is limited, and can be installed where other 6.5" speakers in the same class would not find room.
Flexible in-ceiling installation with dedicated accessories
With an external diameter of 234.6 mm and a depth of 88.7 mm, the Ci160ER requires a cut-out of 196 mm in diameter and suits ceilings with a thickness from 6 to 36 mm. The optional RIF160R pre-installation frame simplifies fitting during the construction phase, while the optional RNC160R rear enclosure improves low-frequency response and acoustic isolation from the cavity.
Reference performance at the value of the Ci-E series
The Ci160ER is intended for those looking for KEF's reference technologies — Uni-Q®, Ultra-Thin Bezel and Weather Resistant construction — on exceptionally accessible terms. Sold as a pair, it is the ideal solution for residential and commercial installations where a 160 mm woofer has to cover medium-sized rooms with full sonic authority. It sits in the KEF Ci-E series alongside its square twin, the Ci160ES, and the 8-inch Ci200ER model, ensuring the same Uni-Q® sound signature at every point of the installation.
