Overview

Delivering high fidelity sound across media, gaming, and commercial AV installation projects, these two way bookshelf speakers feature a four and a half inch driver, a 25 millimeter tweeter, and flexible wall, desk, or floor mounting options for complete audio visual solutions.

The Monitor Audio Radius 3 4G bookshelf speaker is built for situations where space is limited, but sound quality is still important. Its compact size makes it easy to fit into media rooms, gaming setups, multi-room music systems, or commercial AV installations. Inside the cabinet is a four-and-a-half-inch C-CAM RST III driver for mids and lows, paired with a 25-millimeter C-CAM Gold Dome tweeter for high frequencies. Both drivers use their own optimized motor systems to keep audio clear and balanced.

The cabinet uses through bolt driver bracing and HiVe II port technology to help improve sound clarity and bass response. With a ported design tuned to 53 Hertz, the speaker can reach down to 44 Hertz in room and up to 35 kilohertz at the top end. It can handle peaks up to 107 decibels when paired with amplifiers rated between 40 and 75 Watts at 8 Ohms or 75 to 150 Watts at 4 Ohms.

The Radius 3 4G is designed for flexible placement. It can be mounted on a wall using the FIX M bracket, set on a desktop, or placed on dedicated floor stands. The speaker comes in satin white or high gloss black finishes and weighs 3.7 kilograms. A five year manufacturer warranty is included. For a full range system, a subwoofer can be added to support custom audio visual setups.
