For years, the Monitor Audio Radius Series has been the benchmark for compact high-performance speakers. Loved by interior designers, home theatre enthusiasts and music lovers alike, Radius has always proven that exceptional sound doesn't require large cabinets.
Now, Monitor Audio has completely re-engineered the range.
Introducing the Monitor Audio Radius 4G Series—a new generation of beautifully crafted compact speakers that deliver genuine hi-fi performance in spaces where traditional speakers simply won't fit. Whether you're building a discreet stereo system, a stylish home cinema, or a premium multi-room audio setup, Radius 4G has been designed to exceed expectations.
Small Speakers. Big Performance.
The Radius 4G range has been developed using technologies found throughout Monitor Audio's latest loudspeaker ranges. Rather than simply refreshing the appearance, almost every acoustic component has been redesigned to deliver more detail, greater dynamics and lower distortion.
At the heart of the range is the new RST III C-CAM bass/mid driver, featuring an evolved cone geometry, larger motor system and improved suspension design. Combined with Monitor Audio's latest C-CAM Gold Dome Tweeter, Radius 4G produces a level of clarity, speed and realism that is remarkable for speakers of this size.
The result is cleaner vocals, more precise imaging, punchier bass and a richer, more immersive listening experience
Whether you're streaming music, watching films or enjoying live concerts, Radius 4G is engineered to disappear into the room and let the performance take centre stage.
Designed for Modern Living
Today's homes demand speakers that complement contemporary interiors rather than dominate them.
Radius 4G embraces this philosophy with elegant satin finishes, beautifully proportioned cabinets and installation flexibility that allows the speakers to blend naturally into almost any room. They're equally at home on shelves, desks, dedicated floor stands or mounted neatly on walls beside a television.
Available in Satin White and Gloss Black, every model has been engineered to offer premium aesthetics alongside premium performance.
Three Models. Endless Possibilities.
The Radius 4G family has been streamlined into three versatile loudspeakers that can be mixed and matched to suit virtually any application.
Radius 1 4G
The smallest speaker in the range is ideal for surround channels, compact stereo systems, bedrooms, offices and multi-room audio. Despite its ultra-compact dimensions, the Radius 1 delivers impressively detailed and natural sound, making it perfect where space is at a premium.
Radius 3 4G
For listeners wanting greater bass extension and full-range performance, the Radius 3 offers an outstanding balance of size and capability. It's equally comfortable as a bookshelf speaker for music or as the front channels in a premium home theatre.
Radius On-Wall 4G
Designed specifically for modern televisions, the Radius On-Wall model delivers dramatically improved movie and TV sound while maintaining an ultra-slim profile. Pair it with a matching subwoofer and you've got a sophisticated entertainment system that looks every bit as impressive as it sounds.
Built to Grow
One of Radius 4G's greatest strengths is its flexibility. Start with a compact stereo pair and later expand into a surround sound system. Add dedicated floor stands for a minimalist look, wall brackets for discreet installation, or desktop pads for near-field listening. Every component has been designed to work together as part of a scalable audio ecosystem.
Premium Sound Without Compromise
Compact speakers have often required compromises between size, appearance and performance. Radius 4G challenges that assumption. By combining decades of acoustic engineering with Monitor Audio's latest driver technologies, Radius 4G delivers authentic high-fidelity sound from elegantly compact enclosures. It's proof that great audio doesn't need to dominate your room to transform it.
Whether you're building your first premium music system or designing a discreet reference-quality home cinema, Radius 4G offers a solution that's every bit as refined as the spaces it's designed to live in.
