Radius Series 4G seamlessly bridges residential and commercial environments, offering integrators and music lovers an elegantly engineered solution for any interior where premium design and true high-fidelity performance matter.

Designed for on-wall, desktop, wall-mount or stand-mount use, Radius fits seamlessly into any space, whether in commercial environments where design-led solutions matter, or at home around a TV or as unobtrusive room audio.

Features

  • Refined fully vented C-CAM (Ceramic-Coated, Aluminium Magnesium) gold dome tweeter
  • C-CAM cone featuring RST III (Rigid-Surface Technology) cone geometry; powerful and low-mass for superior strength and pistonic motion for true high-fidelity performance
  • Through-bolt Technology to minimise driver fixings for the cleanest aesthetic design, whilst strengthening the cabinet and reducing unwanted resonances
  • HiVe II port technology – up to 50% larger than previous Radius 90 speakers to allow greater control over airflow and turbulence reduction
  • Beautifully finished cabinet finishes and accessories

Radius has never been more adaptable. Its flexibility is its strength: a perfectly considered form, subtle in appearance and premium in every detail, with a sound performance that is both immersive and impactful.

Drawing on Monitor Audio’s 40-plus years of metal-driver innovation, now refined into RST III, the same powerful motor systems and cone geometry found in our class-leading Silver Series 8G, Radius delivers an ultra-realistic, high-fidelity punch.

Expect clear, dynamic TV dialogue, cinematic energy for film soundtracks, refined fidelity for commercial spaces, or simply beautiful high-quality sound without the visual intrusion of larger loudspeakers.

Radius Series 4G – ideal for the integrator for projects that demand beautifully specified loudspeakers, or the perfect miniature hi-fi for the music lover.

Radius Series 4G is the standout choice.
