Monitor Audio Super Slim WSS230 In-Wall Speaker Review
Welcome to our Monitor Audio Super Slim WSS230 In-Wall Speaker Review, where we unpack one of the most exciting developments in home audio design. If you’ve been searching for a stealthy yet high-performance speaker solution that slots into a 2\" stud wall without compromising on sound quality, this new Super Slim WSS230 could be the ticket.

Super-Slim Design Meets High-Fidelity Audio

At just 50mm deep, the WSS230 is engineered to fit seamlessly into 2\" stud walls or areas where traditional speakers simply won’t go. Its slim profile (385 x 140.5mm) elegantly conceals three 3\" C-CAM bass/mid drivers and a 25mm C-CAM Gold Dome tweeter behind a trim-less, magnetically attached grille, allowing it to blend invisibly into your décor.
Acoustic Performance That Punches Above Its Weight
The Super Slim WSS230 harnesses Monitor Audio’s renowned Ceramic-Coated Aluminium/Magnesium (C-CAM) drivers for precision and detail that belies its modest footprint. With a frequency response ranging from 75Hz to 30kHz, 87dB sensitivity and a maximum SPL of 105.6dBA, this in-wall speaker delivers crisp highs, articulate mids and surprisingly controlled bass – especially when paired with a dedicated subwoofer in a home theatre setup.
Technical Deep Dive
Monitor Audio’s proprietary C-CAM cone technology offers an exceptional rigidity-to-mass ratio, significantly reducing distortion and cone break-up at higher volumes. The 25mm gold dome tweeter ensures extended, airy treble with minimal harmonic colouration. Internally, the high-quality crossover network employs selected capacitors, inductors and resistors voiced to maintain phase coherence and ensure a seamless handover between drivers at 100Hz (recommended crossover point at 12dB/octave).
Installation Flexibility and Seamless Integration
The WSS230 is designed for both retrofit and new-build scenarios. Its trim-less grille is paintable to match any wall finish, while the Tri-Grip dog leg fixings provide a secure, rock-solid fit. Gold-plated sprung push terminals ensure effortless connectivity, and the slim enclosure ducks under existing AVC ducts, cabling and pipework without a fuss.
Who Should Consider the WSS230?
- Audiophiles seeking a discreet solution without compromising performance.
- Home theatre enthusiasts aiming for immersive surround sound.
- Architects and interior designers focused on minimalist aesthetics.
- Custom installers and DIYers working with restricted wall cavities.
