The Radius 270 houses a precision-crafted Radius driver system of twin 100 mm (4") C-CAM mid/bass drivers and a 25 mm (1") C-CAM tweeter.


  • 4" C-CAM bass driver - Radius features 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 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.
  • HiVe II port design - 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 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. The through-bolts also act as rigid cross bracing to give a very solid non-resonant cabinet.
  • Front and rear ported reflex design

      Item Condition: Very Good Shipping Options: Pickup available and you can audition. Suburb or Town: Castlecrag (Lower North Shore) State: New South Wales Payment Method: Cash, PayPal Reason for selling: Replaced by new centre Further information:  Selling as moved on from my MA Silver 100's to GX100's, love this centre but needed to go to a ribbon tweeter to match. There are some small scuffs in places where it doesn't matter but looks wise its 8.5/10 and it sounds perfect.

      Item: Monitor Audio Silver Centre Speaker 
      Price Range: Negotiable based on condition etc. 
      Item Condition: New or Used
      Extra Info: To match existing speakers needs to be 5th generation (2014 - 2017) and natural oak finish. 
      Can anyone comment - were these even imported into Australia? 
      Prefer Brisbane for pickup, but OK to have shipped.
