Monitor Audio Platinum 100 3G Monitor Speakers - pair

Pin It

    The new Monitor Audio Platinum Series 3G series offers a choice of four premium models designed to satisfy both two-channel or multi-channel home theatre system configurations. The series consists of the Platinum 100 3G stand mount, Platinum 200 3G mid-sized floor stander, and the formidable, flagship floor stander, the Platinum 300 3G. Each speaker works independently in a high-performance two-channel system, or, with the addition of the Platinum 250 3G centre-channel as part of a high-performance AV system. However you choose to configure them, they will propel the listener into a truly immersive and high-fidelity experience, allowing both music lovers and film aficionados to experience utter perfection.

    PLATINUM 100 3G

    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.

    • 1 x MPD III high-frequency transducer for a larger, clearer, and more lifelike sound
    • 1 x 6” RDT III mid-bass driver for incredible levels of clarity and scale
    • A truly exceptional listening experience from a relatively small loudspeaker
    • Rear-ported and tuned for ease of positioning without affecting sound performance
    • Perfect for smaller high-performance music set-ups, or as front/rear channels in home cinema systems
    • Mount points for the Platinum 2G Stand
    • Cabinets are embellished with etched inlays to highlight the craftsmanship
    • Choice of three high-quality, elegant finishes: Piano Black, Piano Ebony and Pure Satin White

    Re-defining what is achievable for high-end home audio, each model in the Platinum Series 3G features the new 3rd generation Micro Pleated Diaphragm (MPD III) high frequency transducer. Developed by Monitor Audio’s acoustic engineers when creating the company’s ground-breaking ‘Concept 50’ prototype, this breathtakingly accurate tweeter was unveiled earlier this year for our 50th Anniversary celebrations.
