For ultra-discreet sound all around the home, or partnered with the Radius 380 sub for explosive stereo, the original hi-fi mini monitor continues to evolve, incorporating a 4" C-CAM bass driver and 1" C-CAM tweeter.

HiVe II port design - Straight from Platinum’s design blueprint, the HiVe reflex port makes its Radius debut
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
Through-bolts also act as rigid cross bracing to give a very solid non-resonant cabinet
Single point 1/4-inch 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
Available in high gloss white lacquer, walnut real wood veneer and high gloss black lacquer finishes
