New C-CAM, RST III cone
Lightweight, strong and more rigid than conventional materials, C-CAM remains the staple driver cone choice for all Monitor Audio speakers and works pistonically to deliver impressive levels of fidelity, now with an evolved RST cone geometry that reduces breakup and resonances.
New RST III bass/mid driver
A powerful motor system sits behind the light-weight and rigid C-CAM cone. Coupled with optimised surround, new spider design, and increased voice coil diameter, it enables control over deep bass performance, reducing distortion, for punchier, precise bass.
New C-CAM Gold Dome Tweeter
Since 1982, Monitor Audio’s gold dome tweeter has continuously been refined. A precision instrument, the combination of incremental changes over four-decades have ensured it delivers crisp HF with ultra-realism, clarity and detail.
New Crossover design
Hours of listening, and carefully curated component selection, Bronze Series 7G crossovers have undergone extensive measurements to ensure the purest of signal transfer.
HiVe II Ports
The high-velocity II port (HiVe II) design reduces turbulence and support air-flow acceleration within the port, allowing for fast powerful bass and greater transient response.
Through-bolt Driver Bracing
Through-Bolt technology allows the drive units to be securely braced to the rear of the cabinet and tightened to a specific torque to ensure the drive unit and cabinet remain structurally strong, removing unwanted chassis resonances.
Cabinet Design
Monitor Audio is world renowned for the quality and craftsmanship of its cabinetry. Radius Series 4G continues its leadership in this area with beautifully engineered cabinets that present modern satin painted finishes for decreet applications.
