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 Monitor Audio Super Slim WSS130 is an entry-level in-wall speaker from the acclaimed WSS range, built for homeowners and installers who want big sound without a bulky footprint. With a mounting depth of just 50mm, it's ideal for stud walls, renovation projects, and any room where cavity space is tight - from living rooms and home cinemas to multi-room audio installs and light commercial spaces.
Why we like it
- Ultra-slim 50mm mounting depth fits shallow wall cavities with ease
- Three-driver array delivers performance beyond its compact size
- 25mm C-CAM Gold Dome tweeter adds crisp, extended high-frequency detail
- Tri-grip dog-leg fixings make for a fast, secure, and tidy installation
- Shares its cut-out footprint with other WSS models, simplifying future upgrades
Installation notes
The WSS130 requires a rectangular cut-out of 346 x 101mm and a mounting depth of 50mm (54.25mm including the grille), so check wall cavity depth before installing. Rated at 8 ohms with 60W RMS handling (100W with a 100Hz crossover), it pairs well with amplifiers such as the Sonos Amp or a WiiM Amp for streaming-based multi-room setups, as well as traditional AV receivers for home cinema use.

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 50mm 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 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%.
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.
