You'll need an amplifier
These are passive speakers, so they need an amplifier to power them (6Ω, 20–65W recommended). Either of these will drive a pair and stream music from your phone.
Need a fire hood?
If the ceiling has a bedroom or other living space above it, or is part of an escape route, building regulations require each speaker to have a fire hood. Hoods also cut sound leaking into the room above.
Need speaker cable?
Stereo from a single speaker needs a 4-core cable (left and right channels on one run). Allow about 10m back to the amplifier. Webro 16/4 LSZH (low smoke, zero halogen) is the right cable for runs in ceilings and walls.
The Monitor Audio C165-T2 is a 6.5" stereo ceiling speaker designed to deliver full left-and-right sound from a single fitting, making it perfect for bathrooms, hallways, utility rooms, en-suites and other compact spaces where a traditional stereo pair simply won't fit.
Why we like it
- Twin independent, pivoting 1" C-CAM tweeters create a genuine stereo image from one grille
- 6.5" MMP II dual wound voice coil bass driver provides tight, accurate low-end
- Angled tweeters allow sound to be aimed towards the listening area
- Mineral-filled ABS construction is RoHS compliant and built to last
- Compatible with the optional CB6 pre-construction bracket for new-build installs
Installation notes
The C165-T2 requires a cut-out diameter of 211mm and a mounting depth of 114mm (118mm overall depth including grille), so check loft or ceiling void clearance before fitting. Secure Tri-Grip dog fixings hold the speaker firmly in standard plasterboard ceilings. For stereo sources, pair with a compact amplifier such as a Sonos Amp or WiiM Amp to get the most from its dual-tweeter design.

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 211mm cut-out and at least 114mm of depth behind the ceiling surface. The visible trim is 250mm 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 6Ω with 20–65W 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. The hood that fits this speaker is shown above, next to Add to cart. 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?
Orders placed by 1pm Monday to Friday are dispatched the same day. Standard tracked delivery is £7.99, or free on orders over £50; next working day delivery is £11.99. Delivery details.
Can I return it?
