The range celebrates the rich legacy of the Platinum Series, and cements Monitor Audio’s deserved place within the high-end, premium loudspeaker space. Platinum Series 3G encapsulates purity of sound and design, and its launch is a highpoint of Monitor Audio’s 50th Anniversary year.

The Platinum 100 3G is a compact 2-way speaker. With the new RDT III mid-bass driver cone, and MPD III Tweeter, the Platinum 100 3G has been significantly improved over the previous generation. It’s larger cabinet also allows for significant improvements in cabinet bracing. Sound is presented with a purity and precision that makes the Platinum 100 3G an utterly compelling experience. Plus, the speaker includes mount points for the Platinum 2G Stand and the forthcoming universal stand, which will be available soon.

The Platinum 100 3G is engineered to deliver a truly exceptional listening experience from a relatively diminutive loudspeaker.

The speaker also includes mount points for the Platinum 2G Stand and the forthcoming universal stand, which will be available soon.
