Latest Radius Gets a Perfect 10

Designer sat/sub speaker systems come and go, but one just keeps getting better. Back in the 90s Monitor Audio’s Radius showed the industry how to blend high performance and glossy good looks with rooms of any size, shape and colour. The latest Radius evolution burnishes a peerless reputation with even better sound and aesthetics as Danny Philips discovered when testing the new R90HT1 system for Trusted Reviews.

As a former ‘What Video’ editor and an experienced freelance tech journalist, Danny’s qualified to place the R90HT1 at the very top of the pecking order with a perfect 10/10 score and a coveted ‘Editor’s Choice’ badge. Citing a big soundstage from small speakers, superb detail and dialogue clarity and gorgeous build quality and design, he says “it’s beautifully made, offers powerful, polished sound quality and looks stunning – pretty much everything we look for in a speaker system. If you have the cash, it’s worth every penny… If you’re looking for a speaker system on a £1,500 budget then stick the R90HT1 on your shopping list pronto. We’ve heard some pretty special speaker systems of late, including the Quad L-ite Plus and the Cambridge Audio Aero, but the Radius trumps them all”.

New Radius launches with five stars

The next generation of Radius has arrived, complete with new models, greater versatility and higher, wider, deeper sound. The eight-strong model line-up includes still slimmer versions of the 225 centre speaker and Radius One soundbar, together with a new Radius 200 centre-channel for shelf or rack mounting, and two enormously powerful yet super-compact active subwoofers: Radius 380 and 390.

And the re-energised line-up has already shown its quality by collecting five glorious stars from What Hi-Fi? Sound & Vision magazine. In its October 13 issue, the UK’s most dynamic forum for high value AV performance is suitably awed by the new Radius R90 HT1 package, starring the refreshed 90s, new 200 centre and bass-bulging R390 sub. It says “if you yearn for a discrete 5.1 set-up, this should be on your radar, because it’s a remarkable success…integration between fronts, rears and the sub is seamless. The surround field is gapless, effects flow between channels effortlessly and you’re immersed in the action…it (the 390) displays a potent combination of precision and weight with no fear of bottoming out or losing its grip”.

Living with great audio has never been easier.

  • 3" MMP®II Driver. All drivers are dedicated and model specific, with each model in the Radius series being designed and voiced individually.
  • 3/4" gold C-CAM® tweeter, rear-firing to enhance sound dispersion characteristics
  • Single through-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.
  • Single point ¼"x20TPI wall fixing. Use the optional Monitor Audio speaker mount or any standard wall bracket
  • Optional floor-stand with internal (pre-wired) cable management system

  • New 4” C-CAM® bass driver - Radius features all new bass drivers with concave cone profiles, introduced by our top-of-the-range Platinum speakers and applied subsequently to Gold GX.  Extensive research and FEA modelling have allowed us to perfect the relationship between the new radiating diaphragm and its motor design, introducing larger motor sizes and voice coils for increased excursion, higher power capability and reduced distortion.
  • New C-CAM gold dome tweeter - optimised to deliver the finest and widest performance within the compact Radius cabinets. It benefits from a more efficient rear-venting design, releasing air trapped and compressed at the back of the tweeter dome, and guiding it around the drive assembly to a rear-loading chamber.
  • HiVe®II port design - Straight from Platinum’s design blueprint, the HiVe reflex port makes its Radius debut. It’s shaped to have the same effect on airflow as a gun-barrel on a bullet. Rifled grooves inside the port help to accelerate the flow and reduce turbulence, so air moves in and out of the port more efficiently, for a faster more dynamic bass response.
  • 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.
  • Single point ¼”x20TPI wall fixing. Use the optional Monitor Audio speaker mount or any standard wall bracket
  • Optional floor-stand with internal (pre-wired) cable management system.
