Description

The Monitor Audio Radius 3 4G is a high-performance mini-monitor speaker built for TV, film, music, gaming and multi-room applications.

A 4.5-inch C-CAM RST III bass/mid driver pairs with a 25 mm C-CAM Gold Dome tweeter, each powered by its own optimised motor system, to produce expansive, detailed sound far beyond what its compact dimensions suggest.

Through-bolt driver bracing, HiVe II port technology and a precision-engineered crossover work together to deliver tight bass, controlled dispersion and exceptional clarity across the frequency range.

Flexible wall, desktop or floor stand mounting makes the Radius 3 4G easy to integrate into any residential or commercial space, and pairing it with a Monitor Audio subwoofer unlocks truly full-range performance.

Dual-Motor Driver System: A 4.5-inch C-CAM RST III bass/mid driver and 25 mm C-CAM Gold Dome tweeter, each with its own optimised motor, deliver detailed sound with real dynamic headroom.
New Crossover Design: Precision-engineered for the 4G generation to improve integration between the driver and tweeter.
Through-Bolt Driver Bracing: Reinforces the driver mounting for a more rigid, resonance-free cabinet.
HiVe II Ports: Reduce turbulence and port noise for cleaner, more controlled bass.
Flexible Mounting: Wall, desktop or floor stand options via compatible FIX-M brackets suit both residential and commercial installations.
Subwoofer Ready: Pair with a Monitor Audio subwoofer for genuinely full-range performance.
