Monitor Audio Platinum 100 3G
Objects of Desire
Platinum Series 3G is a culmination of ground-breaking acoustic innovations brought together in a number of expertly crafted designs that celebrate the rich legacy of the Platinum Series.
The range cements Monitor Audio’s deserved place within the high-end, premium loudspeaker space and represents a purity of sound and design beautifully entwined – the launch, a highpoint in the brands 50th Anniversary.
The definition of elegance

Platinum Series has always represented Monitor Audio’s engineering and design prowess and the 3rd generation is no exception.
Their UK-based design team worked closely with their acoustic engineers to deliver an aesthetic that celebrates the high-performance components without overpowering its surroundings.
The cabinet design on Platinum Series 3G is all new.
Beautifully detailed and expertly crafted, their industry-leading attention to detail and passion for quality ensures that each cabinet is elegant and refined on the eyes, while being engineered for total acoustic performance.
Constructed using laminated layers of MDF to form a curved and braced super rigid 18-21mm cabinet on the rear with a 36mm thick baffle precision machined to create a unique curved front profile.
The cabinets are then embellished with etched inlays to highlight the craftsmanship, before 16 layers of lacquer are added on top to create a beautiful, luxury piano gloss finish.
A pure satin matte finish is applied to models finished in white – a contemporary statement in any interior.
Aluminium Driver Frames

The drivers on the Platinum Series 3G are held in place with individually cast aluminium frames, creating two layers of isolation between the driver chassis and the cabinet.
The Platinum 100 3G is a compact 2-way speaker that features a MPD III transducer and 6” RDT III mid-bass driver cone.
It offers an utterly compelling listening experience from a relatively small cabinet.
The Platinum 100 3G is engineered to deliver a truly exceptional listening experience from a relatively diminutive loudspeaker.
With its new RDT III mid-bass driver cone and MPD III transducer, the Platinum 100 3G has been significantly improved over the previous generation, and sound is presented with a purity and precision that makes for an astoundingly engaging experience.
The speaker also includes mount points for the Platinum 2G Stand and the forthcoming universal stand, which will be available soon
