Monitor Audio Platinum PL500 II Floorstanding Speakers




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.

Play films and re-live the drama as if they’d written you into the script. As soon as you discover the sheer authenticity of Platinum II, everything will become clear.

That moment will be our reward as well, because we love to share the excitement of creating sound, bursting with natural energy and dynamics. 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.


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 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.


Measured against its peers, there is no finer audio ambassador than the majestic PL500 II.

Here you’ll discover the essence of Platinum II engineering: silken layers of the finest high-frequency definition suspended on an explicit midrange, seamlessly underpinned by a deep, clean and responsive bass foundation. More than ever the sound has a physical authority, conveying the ‘live’ character of instruments, voices and atmospheres as if they had materialised three-dimensionally in the air around you.

This is fidelity in the raw, magnificent in stature, seductive for its rhythmic subtlety and utterly captivating in the sheer magnitude of its dynamic impact. Our most sophisticated system of no fewer than four 8" RDT II bass drivers, twin 4" RDT II mid-range drivers and MPD Transducer will render the entire harmonic sweep of every work with pin-sharp timing and accuracy. Your music and film sound alive, immersive and uncompromised.

"A listen to some tracks from Muddy Waters’ Folk Singer [Analogue Productions 45rpm reissue] conveyed all the intimacy and immediacy of this spare classic recording. Closing my eyes, I felt transported back in time to the 1963 sessions at Chicago’s Tel Arc Studios (aka Chess Records). “My Captain” was reproduced with a startling sense of ambience, presence, and realism as Muddy’s shouts echoed in the recording booth while the sharp transient attacks of his and Buddy Guy’s guitar strings resonated and lingered through clean decays. The spacious soundstaging and specific placement and imaging of snare and bass (both cleanly articulated) were especially striking on "My Home Is in the Delta". "Long Distance" brought long guitar-and bass-string sustains and decays that uh, went the distance. This was captivating, even highly addictive listening!". - The Absolute Sound (2017). Full review here.
