Round frameless speaker flush with the wall or ceiling, with Uni-Q® driver
The KEF Ci130QRfl is a round flush-mount speaker with no bezel (frameless), designed to sit completely flush with the wall or ceiling for a finish of absolute architectural cleanliness. Sold individually, it is part of the KEF Ci-Q series and features the Uni-Q® driver combined with Tangerine Waveguide technology for wide, even sound dispersion. Suitable both for new builds and for retrofit work, it can be integrated directly into the plastering process for a completely concealed result. For those who prefer the square format, the Ci130QSfl model offers the same drivers in a square version.
Uni-Q® and Tangerine Waveguide: a point source for even sound
The Uni-Q® driver places the 19 mm tweeter exactly at the acoustic centre of the 130 mm (5.25") woofer, so that the two drivers act as a single point source. Tangerine Waveguide technology optimises high-frequency dispersion, ensuring even sound coverage over 130° and crystal-clear sound at every point in the room, with a frequency response from 45 Hz to 34 kHz and a maximum SPL of 103 dB.
Round frameless design for absolute architectural integration
The circular format of the Ci130QRfl makes it the natural choice for rooms with curved architectural features, false ceilings with spotlights or any setting where a round profile blends in better than a square one. Like the square model, it has no visible bezel: once installed and plastered in, it disappears completely into the surface, with only the paintable grille left as a visible element.
Intuitive installation in new builds and retrofits
With an external diameter of 200.6 mm and a mounting depth of 101 mm, the Ci130QRfl fits walls and ceilings with a thickness from 7 to 31 mm. The required cut-out has a diameter of 158 mm. The ideal rear volume is 15 L (minimum 10 L). It requires neither a pre-installation frame nor a dedicated rear enclosure.
The invisible speaker for every room in the project
The Ci130QRfl is designed for residential and commercial installations where aesthetics and audio quality have to coexist without compromise. It integrates perfectly with the other speakers in the KEF Ci-Q series — including its square twin, the Ci130QSfl — for multiroom systems, multi-zone audio distribution or discreet surround configurations, maintaining the same Uni-Q® sonic signature at every point of the installation.
