You'll need an amplifier
These are passive speakers, so they need an amplifier to power them (4Ω, 50–350W 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 Ci3160RLM-THX is a high-performance in-wall speaker for dedicated home cinemas. A 6.5in 12th-generation Uni-Q driver with Metamaterial Absorption Technology is flanked by two 6.5in hybrid aluminium bass drivers on a 5.5mm machined aluminium baffle, for THX Certified Ultra output in large rooms.
Why we like it
- 6.5in 12th-generation Uni-Q with MAT
- Two 6.5in hybrid aluminium bass drivers for tight, deep bass
- 5.5mm precision-machined aluminium baffle to cut vibration
- THX Certified Ultra, 110dB maximum SPL
- Paintable magnetic metal grille; optional black cloth grille
Installation notes
The Ci3160RLM-THX needs a 660 x 209mm cut-out and 99mm mounting depth from the surface, and suits walls 6-40mm thick. KEF recommends a 60 litre rear volume (30 litres minimum). It is 4 ohm with 50-350W recommended power, so it needs a capable AV amplifier or power amp.

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 wall?
You'll need at least 99mm of depth behind the wall surface. 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 4Ω with 50–350W 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%.
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.
