You'll need an amplifier
These are passive speakers, so they need an amplifier to power them (8Ω, 10–100W recommended). Either of these will drive a pair and stream music from your phone.
Need speaker cable?
Allow about 10m per speaker for a typical run back to the amplifier. Webro 16/2 LSZH (low smoke, zero halogen) is the right cable for runs in ceilings and walls.
The KEF Ci160QS is a 6.5" square in-ceiling speaker built for anyone wanting high-fidelity, discreet sound in the living room, kitchen, office or home cinema. It suits both dedicated multi-room music systems and immersive home theatre set-ups where a clean ceiling finish matters.
Why we like it
- KEF's renowned Uni-Q driver array places the tweeter at the acoustic centre of the woofer, giving even coverage across the whole room rather than a narrow sound cone
- Ultra-thin square bezel with a paintable magnetic grille disappears into any ceiling colour scheme
- Built-in high-frequency protection circuitry helps protect the tweeter from accidental overload
- Secure, patented mounting system makes for a quick, vibration-free fit during installation
- Flexible 10-100W power handling suits a wide range of amplifiers
Installation notes
Allow a mounting depth of 91mm and a square cut-out of 194 x 194mm when planning your ceiling void. The overall dimensions of the speaker are 223 x 223mm. As a passive 8 ohm speaker, the Ci160QS pairs well with a Sonos Amp or WiiM Amp for streaming-based multi-room setups, or with a traditional AV receiver for dedicated zones.

Questions we get asked
Does it come with a grille?
Yes. Every ceiling and in-wall speaker we sell comes with its grille in the box. Manufacturer photos often show the speaker with the grille removed so you can see the drivers, but the grille is always included.
Will it fit my ceiling?
You'll need a 194mm cut-out and at least 91mm of depth behind the ceiling surface. The visible trim is 223mm across. Standard plasterboard ceilings with joists are usually fine; check for pipes, cables and insulation before cutting. Not sure? Send us a photo or plan and we'll check it for you.
Do I need an amplifier?
Yes. These are passive speakers, so they need an amplifier or AV receiver to drive them. They're rated at 8Ω with 10–100W recommended amplifier power. For most rooms a Sonos Amp or WiiM Amp is ideal: each drives a pair and streams from your phone. You can also buy a package with the amp included and save 5%.
Do I need a fire hood?
If there's a habitable room above (for example a bedroom), or the ceiling forms part of a fire escape route, Building Regulations require each speaker to be fire-rated, usually with a fire hood fitted over the back. Hoods also cut sound travelling to the room above. See all fire hoods.
How many speakers do I need?
As a rule of thumb: a pair for most bedrooms, kitchens and living rooms up to about 20m², two pairs for large open-plan spaces, and a single stereo speaker (T2 / stereo models) for small rooms like en-suites. For home cinema, use 5 or 7 speakers plus a subwoofer. Our free design service will plan positions and sizes from your floorplan.
Is it sold singly or as a pair?
Priced per speaker. Add the quantity you need; most rooms use a pair.
When will it arrive?
