For ultra-discreet sound all around the home, or partnered with the Radius 380 sub for explosive stereo, the miraculously small Radius 45 houses a 3″ MMP II mid-bass driver and rear-firing 3/4″ C-CAM tweeter, and has no right to sound as good as it does.



  • 3″ MMP II Driver. All drivers are dedicated and model specific, with each model in the Radius series being designed and voiced individually.
  • 3/4″ Gold C-CAM tweeter, rear-firing to enhance sound dispersion characteristics
  • Single through-bolt driver fixing. Provides mechanical de-coupling 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.
  • Single point ¼” x 20TPI wall fixing. Use the optional Monitor Audio speaker mount or any standard wall bracket
  • Optional floor-stand with internal (pre-wired) cable management system
