Monitor Audio Super Slim WSS230 In-wall Speaker

Monitor Audio WSS230 In-Wall Speaker

Super-slim in-wall speaker with three 3-inch C-CAM bass-mid drivers, a 1-inch C-CAM Gold Dome tweeter, and just 50mm mounting depth for tighter wall spaces where a conventional speaker will not fit.

The WSS230 is really about solving difficult in-wall installs without settling for throwaway sound. It sits above the WSS130 in the range and is aimed at projects where more critical music reproduction is required. Monitor Audio says it uses its renowned C-CAM metal cone drivers for added sonic precision and detail, while keeping the same super-slim profile that makes the WSS range useful in shallow stud walls and other space-restricted builds.

It can be installed in portrait or landscape orientation, and Monitor Audio specifically notes it can work around screens to maintain neat visuals and identical L-C-R performance.

Super-Slim Design for Tight Wall Spaces

A practical answer when cavity depth is the real problem

The big story here is the depth. The WSS230 has 50mm mounting depth and 54.25mm overall depth including grille, which puts it in a very different category to most in-wall speakers.

Monitor Audio also says it suits constructions featuring 2-inch studs and spaces restricted by ducts, cabling, or pipework. That makes it a strong fit for apartments, renovations, shallow stud work, and tighter media-room or living-room installs where a normal in-wall speaker may simply be too deep.

Step-Up Sound Over the WSS130

More precision and detail for projects where music quality matters more

Monitor Audio explicitly says the WSS230 is a step-up from the WSS130 and is the model to choose where more critical music reproduction is required. It says the use of C-CAM metal cone drivers brings increased precision and more detailed sonic characteristics.

That gives the WSS230 a clear place in the range. It is not just a shallow speaker for difficult walls. It is the more serious slimline option when the install is still constrained, but the customer wants a better result than the entry model is meant to deliver.

Three 3-Inch C-CAM Drivers and Gold Dome Tweeter

Compact on depth, but still built as a proper full-range speaker

The WSS230 uses 3 x 3-inch C-CAM cone bass-mid drivers and 1 x 25mm (1-inch) C-CAM Gold Dome tweeter. That is a more ambitious layout than a typical slim speaker, and it is there to keep the WSS230 feeling like a genuine architectural loudspeaker rather than a compromise panel built only around convenience.

The published spec is 75Hz – 30kHz, with 87dB sensitivity, 8-ohm nominal impedance, and 60W full-range RMS power handling, rising to 100W when used with a crossover set to 100Hz at 12dB/Octave. Monitor Audio also recommends 100Hz minimum crossover with 24dB/Octave optimum when used via AVR or processor.

Built for Controlled, Practical Installation

Slim, but still designed for proper custom-install work

Monitor Audio says the WSS230 uses gold-plated sprung push terminals for bare wire up to 3mm², plus 6-position Tri-Grip dog leg fixings for secure installation.

It also highlights a protective cover to shield the drivers and crossover during the build process, along with a trim-less, paintable grille and replacement scrim for a more discreet finished look.

The Audio Experts Take

The WSS230 makes a lot of sense when the wall cavity is tight but the customer still wants a better result than the entry-level super-slim option. The added precision and detail Monitor Audio talks about is the whole point here. It is still about solving an install problem, but with a bit more sonic ambition.

What we like here is that it looks like a proper problem-solver rather than a compromise product. If a normal in-wall speaker will not physically work, the WSS230 gives you a clean way forward without dropping straight to the bottom rung of architectural audio. For the right project, that makes it a very smart option.
