You'll need an amplifier

These are passive speakers, so they need an amplifier to power them (8Ω, 35–130W 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?

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 Monitor Audio C1M is a versatile 7" in-ceiling speaker built for installers and homeowners who want dependable, full-bodied sound without unnecessary complexity. Its larger mid-bass driver makes it well suited to living rooms, kitchens and open-plan spaces, as well as commercial settings such as offices, shops and restaurants where background music needs genuine depth and clarity.

Why we like it

7" C-CAM mid-bass driver delivers noticeably deeper bass than smaller Tier 1 models
1" C-CAM tweeter with UD waveguide spreads sound evenly across the room
Quik-Link connector allows fast, tool-free cable termination on site
Tri-Grip II fixing system holds the speaker firmly and quietly in the ceiling
Low-profile, paintable magnetic grille blends neatly into any ceiling finish

Installation notes

The C1M requires a 212mm cut-out and a mounting depth of 99mm, so check loft or ceiling void clearance before fitting. A pre-construction bracket (CM-B) is available for new-build projects. With an 8 ohm nominal impedance and 65W RMS handling, the C1M pairs well with multi-room amplifiers such as the Sonos Amp or a WiiM Amp for easy streaming-based background music systems.

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 212mm cut-out and at least 99mm of depth behind the ceiling surface. The visible trim is 242mm 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 35–130W 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.

Can I return it?

Yes. Unused items can be returned within 30 days of delivery, and every product carries the full manufacturer warranty. Returns & warranty.
