Monitor Audio Radius 1 4G Bookshelf Speakers (Pair)

The Monitor Audio Radius 1 4G is an ultra-compact bookshelf speaker built for discreet AV, surround and multi-room sound systems.

Despite its tiny footprint, this pair delivers genuine hi-fi performance thanks to a newly designed 4-inch C-CAM RST III bass/mid driver working alongside a 19 mm C-CAM Gold Dome tweeter.

The result is precise, lifelike sound with exceptional clarity, controlled dispersion and low distortion, all hallmarks of Monitor Audio's metal-driver expertise.

Radius 1 4G suits wall, desktop or floor stand mounting via compatible accessories, and pairing it with a Monitor Audio subwoofer unlocks truly full-range performance.

• Compact C-CAM Driver Array: A 4-inch C-CAM RST III bass/mid driver and 19 mm C-CAM Gold Dome tweeter combine to deliver precise, lifelike sound from a micro-speaker form factor.
• New Crossover Design: Refined for the 4G generation to improve integration between the driver and tweeter for a more cohesive sound.
• Through-Bolt Driver Bracing: Reinforces the driver mounting for a more rigid, resonance-free cabinet.
• HiVe II Ports: Engineered to reduce turbulence and port noise for cleaner bass output.
• Versatile Mounting: Wall, desktop or floor stand options via compatible MASM and FIX-M brackets suit discreet AV, surround and multi-room installations.
• Subwoofer Ready: Add a Monitor Audio subwoofer for genuinely full-range sound when more low-end is needed.
