The compact speaker range, redesigned for residential and commercial spaces, delivers high-fidelity sound in a refined, design-focused form factor.

 

Essex, UK – 15th June 2026: Monitor Audio is proud to announce the launch of the Radius Series 4G, a comprehensive reinvention of one of the brand's most celebrated compact speaker ranges. Built upon Monitor Audio's Transparent Design Philosophy, the Radius Series 4G represents the perfect balance of advanced acoustic engineering and considered, contemporary aesthetics, delivering genuinely high-fidelity sound from speakers that are designed to be seen as well as heard.

 

The Radius Series 4G comprises three speakers: the Radius 1, Radius 3, and Radius On-Wall, alongside a carefully curated range of matching accessories including a custom Floor Stand, Desk Pad, and two Wall Bracket solutions. Together they form a scalable, versatile system capable of serving everything from discreet stereo listening to full multi-channel home cinema, multi-room audio, commercial installations, and near-field desktop environments.

 

Acoustic Performance

At the heart of the Radius Series 4G are a series of significant technological advancements, each developed to raise the performance benchmark of the compact speaker category.

 

C-CAM
Monitor Audio's proprietary C-CAM (Ceramic-Coated Aluminium/Magnesium) cone technology remains central to the Radius 4G's driver design. Lightweight, exceptionally strong, and more rigid than conventional cone materials, C-CAM works pistonically to deliver impressive levels of fidelity.

 

RST III

For this 4th generation, the C-CAM technology makes use of the new RST III (Rigid Surface Technology) cone geometry that further reduces breakup and resonances across the frequency range for an even more accurate, natural sound.

 

Gold Dome Tweeter

The Radius Series 4G introduces a completely redesigned C-CAM Gold Dome tweeter. Departing from conventional architecture, the new tweeter utilises an external magnet motor system, akin to that of a full drive unit, rather than a traditional internal puck magnet.

 

New Crossover Design

The crossover networks in the Radius Series 4G have been subjected to extensive measurement, careful listening, and painstaking component selection. Every element has been curated to ensure the purest possible signal transfer between amplification and drive units.

 

Design

 

Through-Bolt Driver Bracing

Utilising through-Bolt Driver Bracing, the drive units can be securely braced to the rear of the cabinet and tightened to a specific torque, ensuring structural rigidity between driver and cabinet while eliminating unwanted chassis resonances.

 

HiVe II Port

Each Radius 4G features HiVe II (High-Velocity II) port design. This supports smooth airflow and delivers tighter, more controlled bass performance. On the all-new Radius 3 model, the port has  been enlarged by 50% compared to the previous generation to deliver even greater levels of LF performance from its compact form.  

 

Accessories

 

Floor Stands

The custom Radius 4G Floor Stand features wooden tripod legs for a modern aesthetic, with clean cable routing from the terminals down through the stand to the base.

 

Desk Pad

A precision-engineered Desk Pad, made from rubber of a specific hardness for effective vibration isolation, offers a stable platform with a subtle upward tilt for optimal near-field performance.
