Description

Radius 90

For ultra-discreet sound all around the home, or partnered with theRadius 380sub for explosive stereo, the original hi-fi mini monitorcontinues to evolve,incorporating a 4″C-CAMbass driver and 1″ C-CAM tweeter.

Technology

• 4″C-CAMbass driver – Radius featuresbass drivers with concave cone profiles, introduced byour top-of-the-range Platinum speakers and applied subsequentlyto Gold GX. Extensive research and FEA modelling have allowed us to perfect the relationship between the radiating diaphragm and its motor design, introducing largermotor sizes and voice coils for increased excursion, higher powercapability and reduced distortion.
• C-CAM Gold Dome tweeter -optimisedto deliver the finest and widest performance within the compactRadius cabinets. It benefits from a more efficient rear-ventingdesign, releasing air trapped and compressed at the back ofthe tweeter dome, and guiding it around the drive assembly toa rear-loading chamber.
• HiVe IIport design -Straight from Platinums design blueprint, the HiVe reflex portmakes its Radius debut. Its shaped to have the same effect onairflow as a gun-barrel on a bullet. Rifled grooves inside the porthelp to accelerate the flow and reduce turbulence, so air movesin and out of the port more efficiently, for a faster more dynamicbass 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 x 20TPI wall fixing. Use the optional Monitor Audio speakermountor anystandard wall bracket
• Optionalfloor-standwith internal (pre-wired) cable management system.
