What Is a Midi Hi-Fi Component System?
First there was the mini component system (see our CLASSIC minis section), a compact Japanese-style stereo system with separate speakers and, traditionally, individual audio components such as a tuner, amplifier, cassette deck, CD player, or turntable. The concept emerged in Japan during the late 1970s, when manufacturers began producing smaller versions of traditional full-size component stereos. Early systems from companies such as Sony, Technics, Pioneer, Toshiba Aurex, Diatone, and Aiwa combined compact dimensions with technologies previously associated with larger, more expensive hi-fi equipment, including PLL tuners, high-power amplifiers, and advanced power supplies.
During the 1980s, mini component systems became increasingly popular and affordable. Their smaller size made them ideal for homes and apartments, while manufacturers offered complete matching systems that could include amplifiers, tuners, cassette decks, turntables, and speakers. The terms system component and set component were also commonly used. As components became smaller, the terms mini component and micro component system began to describe increasingly compact formats. A micro component was typically around the width of a CD or cassette, while a mini component was generally wider, roughly equivalent to the width of two cassette doors. This led to another practical category of stereo systems: the Midi Hi-Fi system, with components typically around 34–36 cm wide.
Most Midi Hi-Fi systems retained the concept of separate components that could be operated independently, although there were some interesting exceptions. The AIWA 999, one of the finest examples of this category, uses separate-unit construction but connects its components through proprietary cables. Other systems adopted a more integrated, one-box construction, sometimes with the CD player and turntable provided as separate units. These Midi Hi-Fi systems became massively popular in Japan and were marketed under distinctive family names created by individual manufacturers. Examples include:

Rather than simply being smaller versions of traditional hi-fi equipment, these systems represented a distinctive chapter in Japanese audio design, combining compact dimensions, sophisticated technology, striking styling, and the flexibility of component-based systems.
