Super light, yet super strong, the Rigid Diaphragm Technology III (RDT III) cone works like a perfect piston. The ideal technology for elevating both midrange and bass performance, the drivers produce mid frequencies with dexterity, and bass is tight and articulate.
RDT III has three improvements over its predecessor:
A new rear layer featuring two uniform layers of carbon fibre skin to reduce cone breakup
Optimised cone edge treatment to extend passband of drivers
Optimised rubber surround to reduce cone breakup
The result is that the Platinum 3G mid and bass drivers boast the lowest distortion of any Monitor Audio speaker in its history.
