Monitor Audio Radius On-Wall 4G is a slim passive 2-way loudspeaker engineered for wall-mounted TV, film, stereo and multichannel systems. At only 78 mm deep with all accessories fitted, it provides a purpose-built alternative to freestanding speakers where the installation needs to stay close to the wall.
The speaker combines two 4.5-inch RST III C-CAM bass-mid drivers with a 25 mm C-CAM Gold Dome tweeter. Monitor Audio supports both vertical and horizontal installation, making it suitable for left/right, centre-channel-style and surround applications according to the project layout.

Designed around the screen
Radius On-Wall 4G is intended to integrate closely with televisions and projection systems without the visual mass of a conventional floorstanding speaker. The removable Monitor Audio roundel allows the cabinet to present cleanly in either orientation. A wall bracket and fixing template are supplied for installation planning.
Amplifier and system matching
Monitor Audio rates the On-Wall at 8 ohms nominal with a 4.4-ohm minimum at 700 Hz. Recommended amplifier power is 50–100 W RMS into 8 ohms or 100–200 W RMS into 4 ohms. The speaker's 69 Hz published low-frequency limit describes the loudspeaker itself; it does not replace subwoofer planning for cinema systems.
When integrating a subwoofer such as the Monitor Audio Vestra W10, Monitor Audio's Radius support guidance recommends 100 Hz as a starting crossover point. Final bass-management settings should be confirmed during system commissioning.
