Напольная акустика — Monitor Audio Platinum 200 3G

The Platinum 200 3G belongs to the third-generation Platinum Series of UK loudspeaker maker Monitor Audio and is the smaller of its two towers, placed between the Platinum 100 3G stand-mount and the larger Platinum 300 3G. It is a slim three-way tower with a rear-firing port, a cast outrigger and a plinth assembly that also carries the crossover, and it is finished in a choice of Pure Satin White, Piano Ebony or Piano Black with etched inlays as trim. Monitor Audio covers it with a 5-year warranty.

Key specs that matter

Two 6-inch RDT III bass units handle the low band, a single 4-inch RDT III cone covers the midrange, and an MPD III unit takes the treble, with crossover points at 825 Hz and 3 kHz. Monitor Audio publishes two response figures, both at -6 dB - 32 Hz to 60 kHz measured in free field and 23 Hz to 60 kHz in a room. Sensitivity is 88 dB for 2.83 V at 1 m in free field, the nominal impedance is 4 ohm, and the lowest point between 20 Hz and 20 kHz is 4.0 ohm at 2.5 kHz. Continuous power handling is 300 W RMS into 4 ohm, while the recommended amplifier range runs from 150 to 600 W RMS into the same load. With spikes the cabinet measures 1041.6 x 368.7 x 454.9 mm. Each speaker weighs 35.8 kg.

Engineering and use context

The port is tuned to 38 Hz and exits at the back of the enclosure. The RDT III designation is shared by the bass and midrange cones, so every cone in the cabinet comes from one driver family, while the treble unit carries the MPD III name. The crossover network is mounted on the plinth assembly rather than inside the main cabinet. With spikes removed the height is 1025 mm. The cast outrigger widens the footprint well beyond the narrow front baffle, which explains the 368.7 mm width figure against a tall and slim body. RDT stands for Rigid Diaphragm Technology, and MPD for Micro Pleated Diaphragm, a folded ribbon-type tweeter.

Pairing

A 4 ohm load combined with a 150 W lower limit for amplification requires a solid-state amplifier with a stable 4 ohm rating and generous current reserves. The impedance minimum sits at 2.5 kHz, close to the 3 kHz crossover point, so the lowest load falls in the upper midrange rather than in the bass. For a multichannel build, the Platinum In-Wall 3G of the same generation can take the surround or height positions.

Alternatives

The Monitor Audio Platinum 300 3G sits above this tower as the bigger Platinum Series 3G floorstander.
