Round in-ceiling speaker with 160 mm Uni-Q® driver
The KEF Ci160.2CR is a round two-way flush-mount speaker from the Ci-C series, designed to offer an ideal introduction to the world of custom installation speakers with KEF's distinctive technologies. Sold singly, it is fitted with a 160 mm (6.5") woofer with a 16 mm (0.6") aluminium dome tweeter with tangerine waveguide 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 aesthetic integration, while the IP64 certification also makes it suitable for environments subject to humidity and UV rays. 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 Ci160.2CS.
Uni-Q®: wide, even dispersion throughout the room
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 provides wide, even sound dispersion throughout the room, allowing the listener to hear the sound with full fidelity regardless of their position relative to the speaker — an essential feature for in-ceiling installations, where the listening position is not always predictable.
Shallow mounting depth for a 6.5-inch speaker
With a sensitivity of 89 dB, a response that extends down to 52 Hz and compatibility with amplifiers from 10 to 100 W into 8 Ω, the Ci160.2CR is suitable for living rooms, bedrooms, home theatre zones and high-level multiroom distribution. The mounting depth of only 84.5 mm — exceptionally shallow for a 6.5" speaker — allows it to be installed where other speakers in the same class would not find space, making this model a preferred choice even in structurally constrained settings.
Flexible in-ceiling installation with dedicated accessories
With an external diameter of 234.6 mm and a depth of 88.7 mm, the Ci160.2CR requires a cut-out of 196 mm in diameter and fits ceilings with a thickness from 6 to 36 mm. The optional RIF160R pre-installation frame simplifies fitting during construction, while the optional RNC160R rear enclosure improves the low-frequency response and the acoustic isolation from the cavity.
The introduction to KEF custom installation in round format
The Ci160.2CR is designed for those approaching the world of architectural speakers who are looking for a round in-ceiling format without giving up KEF's reference technologies. The Weather Resistant treatment with IP64 certification protects the components from humidity and UV rays, extending the installation options to bathrooms, kitchens and uncontrolled environments. It fits perfectly into the KEF Ci-C range alongside its landscape-format twin, the Ci160.2CL, providing the same Uni-Q® sound signature at every point of the installation.
