Radius R90HT1

February 2014

"One of the best compact 5.1 systems money can buy? Certainly."

The Radius R90HT1 speaker package achieved a Best Buy award and review In the latest issue of Home Cinema Choice magazine. Danny Phillips provides an in-depth account of his experience with our system:

"Whether pounding out the funky basslines of an Earth Wind and Fire track or teasing the darkly mellifluous tones of Gretchen Parlato's Henya, the R90HT1 demonstrates outstanding timing, agility and detail retrieval."

"Seamless, coherent soundstage; wonderful detail reproduction; superb bass grip and slam; stunning design."

Radius 45

September 2013

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.
