Overview
A pair of high-fidelity loudspeakers featuring a distinctive multi-tweeter array designed for wide high-frequency dispersion. These speakers are housed in walnut-grain vinyl-clad cabinets with iconic sculpted foam grilles that define the 1970s 'audiophile' aesthetic.
Story
In 1973, New York engineers launched these to solve the 'sweet spot' problem. By using a fan-like array of five tweeters, they ensured the music sounded perfect no matter where you sat in the room. They were the underdog's answer to the hi-fi giants.
Maker / Origin
Micro-Acoustics was a specialized boutique firm founded by Arnold Schwartz and Norman Dieter, former engineers from United Audio. While they became legendary for their high-end phono cartridges, their 'Full Range Monitor' (FRM) speakers are cult favorites among vintage audio enthusiasts for their unique engineering.
Condition & Value
The cabinets show some surface wear and the foam grilles appear to be original but are showing typical signs of age-related degradation and dust accumulation. The presence of the original warranty card and serial numbers is a major plus for collectors. Condition of the internal drivers is unknown.
