Monitor Audio Platinum 300 3G - Floor Standing Speaker - Pair

Monitor Audio Platinum 300 3G - Floor Standing Speaker - Pair

The Platinum 300 3G’s combination of MPD III transducer, 4” RDT III mid-range driver and two 8” RDT III bass drivers allow it to deliver exceptional scale and depth. The worthy flagship of the Platinum Series 3G, this loudspeaker is quite simply the best in its class.

The Platinum 300 3G, the flagship of the Platinum Series, represents the absolute pinnacle of what is achievable at its price-point in terms of both performance and design. The combination of the innovative new MPD III transducer and the RDT III mid-range and bass driver cones, allows the speaker to deliver exceptional scale and depth. With a totally immersive soundstage and believably lifelike performance, 300 3G’s presentation of music and film is astonishing. The Platinum 300 3G’s expertly crafted design and innovative acoustic system performance, ensures that it will remain relevant for a lifetime.

Micro Pleated Diaphragm III

Redeveloped to celebrate Monitor Audio’s 50th Anniversary, the Platinum 3G series benefits from a great step-up in precision. Discover a new level of appreciation for your favourite tracks. The MPD III can derive overlooked subtleties from even the most familiar of film and music, with a frequency response over 60kHz and diminished crossover colouration. The new waveguide geometry also ensures directivity for articulate detail and coherency.

Rigid Diaphragm Technology III

The Platinum 300 takes full advantage of it’s size with two eight-inch RDT III woofers and a dedicated four-inch midrange driver. Capable of breaching frequency levels usually dedicated to powered subwoofers, these speakers are optimised for power handling and delivering fine detail across a nuanced soundscape. Lightweight and sturdy, two thin layers of carbon fibre helps avoid cone breakup to enforce a clearly defined frequency range.

New Cabinet Philosophy

Countermeasures against distortion have been implemented through the design of the cabinet. From the tuned rear ports to the dual layer aluminium driver frames, the Platinum 300 3G is well isolated against rattle and turbulence during intense playback. New outrigger legs keep the loudspeaker stable, with the strength required for easier walk-in positioning and ergonomic, top-down feet levelling instead of tipping the speaker to adjust the height.
