Monitor Audio’s flagship loudspeaker range, Radius, has been enhanced with revamped Radius 45, 90 and 270 designs, and a new eight-strong model line-up. It includes slimmer versions of the 225 centre speaker (65mm depth) and Radius One soundbar, in addition to a new Radius 200 centre-channel speaker and two powerful yet super-compact active subwoofers: Radius 380 and 390.
Key performance enhancements come from new all-metal driver configurations. The new range utilises C-CAM bass drivers, featuring concave cone profiles introduced originally by the the company’s Platinum series and subsequently on its Gold GX. The drivers benefit from the latest developments in cone geometry and drive mechanisms to extract optimum performance from Monitor Audio’s signature C-CAM material.
Unlike conventional cones, which incorporate a centre aperture for the voice-coil, the new Radius bass cones take the form of a continuous rigid surface, coupled to a longer voice coil and larger motor. THe company says the wholly revitalised Radius bass drivers offer greater drive force, longer excursions and lower distortion, producing cleaner, more extended and accurate bass definition.
In addition, a new 25mm C-CAM tweeter has been developed to deliver what is said to be the widest, cleanest frequency range possible from the compact Radius cabinets. The Radius tweeter vents internally through a specially designed housing and around the outside of the magnet system to a rear-loading chamber for much lower resonance and better damping. As a result lower frequencies at the crossover point with the bass driver are more accurately resolved, creating a smoother, more natural response from the system.
