Ariston MSX-03 Micro Monitor (production years unknown)
The MSX-03 is a footnote in Ariston's catalog. The company is remembered for turntables - the RD-11, RD-40, RD-80 and others - so this compact two-way loudspeaker was a rare detour into speakers, and the documentary trail is thin. No production years, no original price, and no period reviews have surfaced.
What the resale listings agree on: the MSX-03 is a small cylindrical two-way, finished in black in the listings that note the color, about 20.6cm tall and 15cm in diameter, with a 100mm polypropylene-cone bass driver and a 25mm polymer dome tweeter. Nominal impedance is 8 ohms. The fullest spec sheet found recommends a 15–30W RMS amplifier and lists a 45W maximum; another listing claims "100 watts" in its title, which may be a different revision or simply a loose listing claim. The shape suited shelf or wall mounting — several listings include brackets — and one seller described them as great for surround-sound or stereo use. A single weight figure of just over five pounds fits the space-conscious intent. One listing records the frequency response as "85Hz–20Hz," which appears to be a typographical error; no corrected figure survives in the record.
The MSX-03 evidently had siblings - the MSX-05, MSX-07, and MSX-M appear in resale listings - but no documented relationship between them exists.
