At a Glance
The Radius One incorporates a string of C-CAM drivers arranged in three sets of 100 mm (4") bass driver/ 25mm (1") tweeter pairings, each with its own dedicated reflex-ported chamber. The innovative shallow-profile drivers introduced by the Radius series allow us to generate the triple impact of left, centre and right channels from a cabinet that's 40% smaller than its predecessor.

  • 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.
  • 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.
  • 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.
  • Wall mounting bracket Included
  • This product is now available to use with home theatre design software, The CEDIA Designer.
