Technology

Radius 270 technology
  • 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.
  • Front and rear ported reflex design

Radius 270 Tower Speakers Review

"The 270 is a simple, elegant little speaker..."

"My ears perked up right away when I heard the super-spacious, ambient soundstage the Radius 270 threw out on guitarist Gabor Szabo's The Sorcerer, a 1967 side recorded live at the Jazz Workshop in Boston."

"Marty Morrell's snare and cymbals seemed to be echoing off the hard walls of a medium-sized club. I loved the way the Radius 270 seemed to recreate the acoustics of the venue so precisely."

"Steely Dan's "Aja" sounded very smooth, with the hard-to-reproduce piano in the recording showing no trace of the unpleasant hardness most speakers give it. The 270s treated Donald Fagen's reedy voice just as carefully."

"Toto's "Rosanna," sounded positively huge through the Radius 270, with the colossal, reverberant sound I imagine the group was going for."

"I liked what the Radius 270 did with vocals in general; every singer I played through it sounded smooth, with no notable sibilance or midrange coloration."

"These are excellent results. Any speaker that measures with no more than a ±3 dB variation on-axis is generally considered to be pretty well-engineered, and the Radius 270 meets that standard easily."

"The advantage of the Radius 270 is that it gives you the refinement of those speakers in a form factor that's vastly more appealing and much less likely to garner complaints from your significant other."

Radius 45

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.
