Monitor Audio Radius R45HD10 AV

The R45HD10 offers a tuneful, controlled and powerful sound stage from speakers whose performance defies their size

R45HD

The diminutive R45HD is the perfect satellite speaker for front left- centre-right and rear surround sound applications. Its secret is a combination of a 75mm (3) MMPII cone mid-bass driver and rear-firing 20mm () C-CAM gold dome tweeter, which spreads and magnifies the sound around the room to create a huge, encompassing surround sound effect. Designed to dovetail with the R360HD subwoofer and available in the RadiusHD range of real wood veneers and lacquers, the R45HD will blend perfectly with your dcor in an ultra-discreet, multi-channel audio or video system. Installing the R45HD on the ceiling or wall is easy by using the high quality angled bracket supplied. Use the optional bespoke RadiusHD stand for floor positions.

Features:

3 MMPII. 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.

3/4" gold C-CAM tweeter, rear-firing to enhance sound dispersion characteristics and providing extension to in excess of 35 KHz. Ensuring the wide frequency bandwidth of HD music and cinema formats can be replayed faithfully.

Single though-bolt driver fixing. Provides mechanical de-coupling properties resulting in enhanced mid-band clarity and resolution. Through-bolts also act as rigid cross bracing to give a very solid non-resonant cabinet.

Internal PTC auto-reset protection circuit to prevent over-driving.

Magnetically shielded drivers for safe use near sensitive microprocessor equipment or plasma/LCD displays.

Rigid MDF construction throughout.

Smooth radius edges reduces diffraction effects and gives better imaging properties.

Flush fitting grille with rotate-able m logo for positioning in Landscape or portrait orientation.

A specially designed die-cast metal wall bracket is supplied, providing easy install and adjustment for wall positioning

R180HD

The slightly larger and more versatile R180HD offers the same irresistible blend of virtues as the R90HD, but can be installed vertically as a main, side or rear speaker, or horizontally as a centre channel speaker using the bespoke low-profile wall bracket supplied. Its enhanced bass performance makes it ideal for discreet music applications around the home. Combined with a R360HD or R370HD subwoofer however, the R180HD will form part of a formidably powerful stereo or multi-channel home cinema system.

Features:

4" MMPII. 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.

Specially developed high grade PCOFC internal cable is used throughout to ensure maximum signal transfer at all frequencies and low signal resistance.

ARC front baffle (Anti-Resonance Composite). Originally developed for our high-end Platinum series, ARC is a cast thermo-set polymer loaded with minerals to provide very inert, optimally damped components. It is ideal for high-end acoustic applications where a high degree of structural rigidity and vibration damping is required.

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 firing port.

Internal PTC auto-reset protection circuit to prevent over-driving.
