British audio specialist Monitor Audio has unveiled its new Radius Series 4G speaker range, introducing a trio of compact models designed for both hi-fi enthusiasts and home cinema users. The company says the latest generation delivers “genuinely high-fidelity sound” while maintaining a design aesthetic intended to complement modern living spaces.
The new line-up includes the Radius 1, Radius 3 and Radius On-Wall speakers, with the latter specifically designed for wall-mounted installations in home entertainment systems.
Monitor Audio Targets Premium Compact Speaker Market
Monitor Audio describes the Radius Series 4G as a “comprehensive reinvention” of its previous Radius Series 3G range. The British manufacturer is positioning the new models as a significant step forward in the compact speaker category, claiming they establish a new benchmark for performance in smaller audio systems.
The speakers are intended to work across a variety of set-ups, from traditional stereo hi-fi systems to immersive home cinema arrangements. Multi-room compatibility is also supported, reflecting the growing demand among UK consumers for flexible whole-home audio systems.
New Driver Technology Promises Greater Audio Accuracy
At the core of the Radius Series 4G is Monitor Audio’s latest C-CAM (Ceramic-Coated Aluminium/Magnesium) cone technology. According to the company, the material is lighter and more rigid than conventional speaker cone materials, allowing for improved sonic precision and reduced distortion.
Fourth-Generation C-CAM Design
The latest drivers also incorporate the brand’s RST III (Rigid Surface Technology) cone geometry. Monitor Audio says this design helps minimise resonance across the frequency range, resulting in more accurate and controlled sound reproduction.
The company has also redesigned its Gold Dome tweeter system. Instead of relying on a traditional internal puck magnet arrangement, the new tweeter uses an external magnet motor system that Monitor Audio claims behaves more like a full drive unit, potentially improving detail retrieval and clarity.
Enhanced Bass Performance
Another notable inclusion is Monitor Audio’s HiVe II port technology. The updated port design is engineered to improve airflow efficiency, which the company says results in tighter and more controlled bass output — an important consideration for compact speaker systems often used in smaller UK homes and flats.
Flexible Design for Hi-Fi and Home Cinema Set-Ups
The Radius On-Wall model is expected to appeal particularly to home cinema users seeking a cleaner, space-saving installation. Promotional imagery released by Monitor Audio shows multiple On-Wall speakers integrated into a surround-sound arrangement.
Alongside the speakers themselves, Monitor Audio is also offering a selection of optional accessories. These include the Radius Floor Stand, priced at £300, which features wooden tripod legs intended to match contemporary interior design trends.
A separate Desk Pad accessory, costing £30, has also been introduced to provide angled desktop placement for improved listening performance.

The Radius Series 4G range launches with the following UK pricing:

US pricing has also been confirmed, reflecting Monitor Audio’s continued focus on international markets.
Strong Heritage Raises Expectations
Monitor Audio has built a strong reputation among audiophiles and home cinema enthusiasts in recent years. Several of the company’s previous speaker models, including the Studio 89 and Bronze 50 7G, have received critical acclaim for their balance of performance and design.
While the Radius Series 4G has yet to undergo independent testing, the combination of upgraded acoustic technology, compact form factor and versatile installation options is likely to attract attention in the increasingly competitive premium speaker market.
For consumers seeking discreet speakers capable of delivering high-quality audio in smaller living spaces, the Radius Series 4G appears aimed squarely at that growing segment of the market.
