Benefits of Monitor Audio Radius 90 Bookshelf Speaker:
Performance That Outpaces the Size
The compact Radius 90 is a surround speaker with a size-defying performance. Its secret is the 4″ C-CAM Driver and a 1″ rear-firing gold C-CAM tweeter, which spreads and magnifies the sound around the room to deliver a huge, encompassing surround sound effect. All drivers are dedicated and model-specific, with each model in the Radius series being meticulously designed and voiced individually.
HiVe II Port Design Helps Reduce Turbulence
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 with enhanced efficiency, for a faster, more dynamic bass response.
Single Through-Bolt Driver Fixing Renders Mechanical Decoupling Properties
Single through-bolt driver fixing provides mechanical decoupling properties, resulting in enhanced mid-band clarity and resolution. Through-bolts also act as rigid cross-bracing to give a very solid, non-resonant cabinet. It is also feature-packed with a single point ¼” x 20TPI wall fixing. Feel free to use the optional Monitor Audio speaker mount or any standard wall bracket or optional floor-stand with an internal (pre-wired) cable management system.
