Monitor Audio Radius 4G On-Wall Speaker (Single), Satin White Overview
The Monitor Audio Radius 4G On-Wall Speaker, is designed for discreet TV, film, and music systems where clear sound needs to sit neatly around a screen. Its slim 78mm-deep cabinet uses two 4.5-inch C-CAM bass-mid drivers with RST III geometry and a 25mm C-CAM Gold Dome tweeter, giving it the output and clarity needed for front left, centre, right, or surround channel use.
With 100W continuous power handling, 90dB installed sensitivity, and a 69Hz to 35kHz in-room frequency response, the Radius On-Wall 4G is well suited to compact cinema systems and living room AV setups. Its ported cabinet uses HiVe II technology for cleaner airflow and tighter bass, while the supplied wall bracket and fixing template help keep installation straightforward. The removable Monitor Audio roundel also allows tidy vertical or horizontal placement.

Full Description
View Full DescriptionTwin RST III C-CAM Drivers
The Radius On-Wall uses twin 4.5-inch C-CAM bass/mid drivers with RST III cone geometry, giving it extra surface area while keeping a slim wall-friendly profile. The rigid cone shape helps control flexing, so speech, effects and instruments remain cleaner as volume rises. An improved motor system manages the driver movement more accurately, supporting firmer bass and clearer midrange from a shallow cabinet. Reduced breakup and lower resonance help the speaker stay composed, making it useful beside a screen or across a discreet front soundstage at home setups.
C-CAM Gold Dome Tweeter
The Radius On-Wall includes a 25mm C-CAM Gold Dome tweeter to give treble enough reach for wider room layouts. Its vented design reduces pressure behind the dome, helping high frequencies sound cleaner and less strained during busy scenes or layered music. The UD Waveguide shapes dispersion, so detail spreads more evenly across your seating position rather than narrowing into one small sweet spot. This helps the tweeter integrate with the twin 4.5-inch drivers, giving voices, effects and stereo imaging a smoother, more joined-up character in daily use.
Slim Wall-Mount Cabinet Design
The Radius On-Wall cabinet is designed for clean installation where floor space is limited, giving you a neat route to stronger front or surround channels. Through-bolt bracing reinforces the structure, reducing cabinet vibration and helping detail stay focused. The crossover manages the handover between the twin bass/mid drivers and tweeter, so the sound feels balanced rather than separated. HiVe II port technology improves airflow through the cabinet, helping low frequencies stay agile and controlled while keeping the speaker slim enough for practical wall placement in living rooms.
