Platinum Series II

If a pin drops, you’ll hear it. When the orchestra plays, it plays for you, so vividly and with such effortless scale you’ll believe you’re ten rows from the stage. This is the magic of high-end audio as experienced through the Platinum II speakers. Whether it’s a power chord exploding from a towering backline, the majesty of a choir soaring in union or the spell-binding gravity of a solo performance, you’ll sense the chemistry of music and musician more than ever before.

For over forty years our work as engineers and audio enthusiasts has been dedicated to this unveiling. With our most advanced driver, crossover and acoustic systems set within luxurious cabinets, we’ve tuned the virtues that have won Monitor Audio worldwide acclaim to a new intensity, allowing rarefied audio transparency to be revealed and enjoyed. Platinum II is our magnum opus, as inspirational and satisfying to us as we hope it will be to you.

Platinum II Range

Platinum II Range

  • New RDT®II drivers with C-CAM® technology
  • MPD (Micro Pleated Diaphragm) high frequency transducer, designed in-house for Platinum II
  • HiVe®II High Velocity reflex port
  • ARC® (Anti-Resonance Composite) mid-range driver housings and baffle components
  • New patented 'DCF' (Dynamic Coupling Filter) mechanism for more natural sound



The Platinum II cabinets are a statement of immaculate craftsmanship. Each is hand-built with the expert precision of the finest furniture makers, employing multiple laminations of veneer that are formed into a curved rigid shell. For the finish, natural wood veneers in Santos Rosewood or Natural Ebony are pair-matched, applied and hand-coated with 11 layers of clear gloss piano lacquer, then polished to reveal the glowing lustre in the grain. Platinum II models are also available in a penetrating piano black gloss lacquer, which will offer a luxurious contrast with room décor.

The front baffles are hand-upholstered with the very highest quality Inglestone leather supplied by Andrew Muirhead and used to distinguish many luxury British brands. Such is the level of care lavished on the Platinum II enclosures that each requires as many as 144 hours to complete.



Platinum II offers you genuine audiophile performance with stunning design and materials specification. In the pursuit of ever lower distortion, no detail has been overlooked. Through meticulous FEA modelling we’ve optimised the operation of electrical, mechanical, magnetic and acoustic systems, introducing new discoveries to meet ambitious performance goals. The Platinum II range deploys an enhanced generation of RDT® bass and mid drivers, and for the first time in a Monitor Audio product, the MPD (Micro Pleated Diaphragm) high frequency transducer. Including improved crossover and speaker terminal designs together with proprietary ARC®, TLE, HiVe®II technologies, Platinum II builds on the award-winning advances of over forty years to create a high-end speaker range that is utterly faithful to the source.
