Platinum 100 3G

The Platinum 100 3G is a highly refined, compact two-way speaker that exemplifies Monitor Audio’s commitment to high-performance audio engineering in a smaller, versatile form factor. Despite its relatively modest cabinet size, the Platinum 100 3G delivers a rich, engaging, and utterly compelling listening experience, offering clarity, precision, and depth that belies its compact footprint.

At the core of its impressive performance is the MPD III high-frequency transducer, which produces sparkling, detailed highs with exceptional clarity and minimal distortion. Complementing this is a 6-inch RDT III mid-bass driver, carefully engineered to deliver tight, controlled low and midrange frequencies, providing a solid foundation for music or cinematic soundtracks. Together, these drivers create a coherent, natural, and immersive sonic presentation, making the Platinum 100 3G an ideal choice for smaller listening spaces without compromising on fidelity.

The speaker features a rear-ported cabinet, enhancing airflow and bass response, while ensuring the sonic performance remains balanced and full-bodied. For flexibility in placement, the Platinum 100 3G includes mount points compatible with the previous Platinum 2G Stand and is directly compatible with the new ST-2 Universal Stand, allowing users to position the speakers optimally for the best audio experience.

Elegantly finished and embellished with etched decorative inlays, the Platinum 100 3G is available in Piano Black, Piano Ebony, and Pure Satin White, ensuring it complements a wide range of interiors. Its combination of compact size, high-end design, and sophisticated acoustics makes it perfect for high-performance music systems in smaller rooms, desktop setups, or dedicated two-channel listening environments.
