Monitor Audio Radius HD R270 HD10 AV

The R270HD is a super-slim floor-standing loudspeaker designed for genuine full-range performance in a serious music system or multichannel audio/video system. Excellent fidelity from twin 100mm (4”) MMP®II mid/bass drivers and a 25mm (1”) C-CAM® gold dome tweeter, coupled with a svelte profile provides the opportunity to enjoy great sound and discreet design all in one package. A choice of luxury real-wood or lacquer finishes supplies a lustrous appeal, giving the R270HD a tactile sense of quality that feels at home anywhere.

Features:
• 2 x 4" MMP®II. The Metal Matrix Polymer drivers have been completely re-worked and re-modelled with the aid of new design and simulation tools to achieve higher sensitivity and increased magnetic linearity. The new shaped T-section pole and focussed magnetic gap produces better linearity and lower distortion, resulting in fast punchy bass. All drivers are dedicated and model specific, with each model in the Radius HD series being designed and voiced individually.
• 1" Gold C-CAM® tweeter providing extension to in excess of 35 KHz ensuring the wide frequency bandwidth of HD music and cinema formats can be replayed faithfully.
• Magnetically shielded drivers allow Radius HD to be safely used near sensitive microprocessor equipment or plasma/LCD displays.
• High quality crossover uses high-grade metalised Polypropylene capacitors for increased clarity. High-grade air core and laminated iron core inductors give lowest possible distortion and low insertion losses.
• Terminals are located on the plinth for ease of cable management and routing.
• Specially developed high grade PCOFC internal cable is used throughout to ensure maximum signal transfer at all frequencies and low signal resistance.
• Single through-bolt driver fixing provides mechanical de-coupling and enhanced mid-band clarity and resolution. The through-bolts also act as rigid cross bracing to give a very solid non-resonant cabinet.
• Front and rear ported reflex design.
• Internal PTC auto-reset protection circuit to prevent over-driving.
• Mass loaded cabinet lower section (factory filled) provides better stability and bass damping.
• Taller cabinets – for better imaging and cosmetic appearance.
• Flush fitting grille with rotate-able ‘m’ logo for positioning in Landscape or portrait orientation.

The R90HD is a high-class mini monitor. Unprecedented enclosure rigidity and leading edge drive unit technology in the shape of a 100mm (4”) MMP®II mid/bass driver and 25mm (1”) C-CAM® gold dome tweeter combine to produce clarity, dynamics and imaging abilities that are unparalleled in a speaker of this size. It can fill a room with high fidelity sound and yet visually melt into the background. The R90HD can be installed easily on ceiling or wall using the same high quality angled bracket supplied. Use the optional bespoke RadiusHD stand for floor positions.

The slender R225HD’s contoured profile is designed to match the aesthetic of flat plasma and LCD displays. When used as a centre channel or main speaker, its acoustic design of twin 100mm (4”) MMP®II mid/bass drivers and 25mm (1”) C-CAM® gold dome tweeter provides the signature accuracy of Monitor Audio’s reference speakers. Its impressive size-defying bass performance can be further extended with the addition of a RadiusHD active subwoofer. Use it with the R360HD or R370HD subwoofer to create a compact, perfectly matched yet sonically exhilarating audio/video speaker system. Supplied with a low-profile bracket for horizontal or vertical flush-mounting on the wall, the R225HD can be customised to complement its environment for the perfect balance of styleand performance.
