In today's fast-paced world, where space is often at a premium, the launch of Monitor Audio's Radius Series 4G speakers is a welcome innovation. This British audio brand has taken a fresh approach to compact speakers, offering a range that not only delivers high-fidelity sound but also prioritizes contemporary aesthetics.
The Evolution of Compact Speakers
Monitor Audio's Transparent Design Philosophy is at the core of the Radius Series 4G. This philosophy aims to strike a perfect balance between exceptional acoustic engineering and visually appealing designs. The result is a collection of speakers that are as much a pleasure to look at as they are to listen to.
The series consists of three distinct models: the Radius 1, Radius 3, and the innovative Radius On-Wall speaker. Each speaker is designed to cater to a variety of audio needs, from stereo listening to multi-channel home theater setups, multi-room audio, and even commercial installations.
Technological Advancements
At the heart of the Radius Series 4G's performance is Monitor Audio's proprietary Ceramic-Coated Aluminum/Magnesium (C-CAM) cone technology. This lightweight yet rigid material allows the speakers to deliver high levels of fidelity, ensuring a natural and accurate sound reproduction.
For this 4th generation, Monitor Audio has enhanced its C-CAM technology with Rigid Surface Technology, which reduces breakup and resonances across the entire frequency range. This innovation is key to the Radius 4G's ability to produce a more precise and lifelike sound.
The series also introduces a redesigned C-CAM Gold Dome tweeter. By utilizing an external magnet motor system, the new tweeter design mimics that of a full drive unit, offering improved performance over the more conventional internal puck magnet design.
Enhanced Bass Performance
The Radius Series 4G features a new crossover design, carefully crafted through extensive measurement and listening tests. Every component has been selected to ensure the purest signal transfer between amplification and drive units.
Monitor Audio's Bolt Driver Bracing technology further enhances the speakers' performance by securely bracing the drivers to the rear of the cabinet. This design eliminates unwanted chassis resonances, ensuring a more precise and controlled sound.
The High-Velocity II port design, featured in each Radius 4G speaker, supports smoother airflow and delivers a tighter, more controlled bass performance. On the Radius 3 model, the port has been increased by 50% compared to the previous generation, resulting in improved low-frequency performance despite the compact size.
Speaker Accessories
Monitor Audio has also developed a range of accessories to enhance the user experience. The custom Radius 4G floor stand, with its wooden tripod legs, adds a modern twist to the speakers' aesthetic. The stand also provides a clean cable routing system, keeping the setup neat and organized.
For near-field recording monitors, a precision-engineered desk pad is available. Made from rubber of a specific hardness, this pad provides effective vibration isolation, ensuring a stable and tilt-free platform for the speakers.
Pricing and Availability
The Monitor Audio Radius Series 4G will be available from June 2026, with prices starting at $525 / £425 / €475 per pair for the Radius 1 4G. The Radius 3 4G is priced at $725 / £575 / €675 per pair, while the Radius On-Wall speaker is available for $575 / £450 / €525 per piece. Accessories, including the floor stand and desk pad, are also available at competitive prices.
Final Thoughts
Monitor Audio's Radius Series 4G is a testament to the brand's commitment to innovation and design. By combining cutting-edge technology with a focus on aesthetics, they have created a range of compact speakers that are not only sonically impressive but also visually appealing. This series offers a versatile and stylish solution for modern spaces, catering to a wide range of audio needs. Personally, I think this is a brilliant step forward in the world of audio, and I'm excited to see how these speakers perform in real-world settings.
