¥ 70,000 (1 unit, around 1991)
Commentary
A tall boy type speaker system with a 3-way configuration.
A 20.3 cm cone woofer is installed in the low range.
IMG (Injection Molded Graphite) cone is used for the diaphragm. This material combines polypropylene and high-rigidity graphite fiber to ensure moderate internal loss and high strength.
A 12.7 cm cone type squaker using IMG cone is mounted in the middle area.
The IMG cone used in the mid-range has achieved high rigidity with a light mass by selecting the mixing ratio of polypropylene and graphite fiber.
In addition, the cone center, where physical stress is concentrated, uses a dust cap to enhance rigidity.
The high-frequency band is equipped with an EMIT-R type tweeter that is an improvement of the EMIT-type tweeter based on Infiniti's unique technology.
The EMIT-R uses a flat diaphragm with a diameter of 3 cm to achieve transient characteristics, low distortion rate and wide-range reproduction, which are the major features of the EMIT-type tweeter.
The enclosure is hermetically sealed.
The exterior has a Chatsworth Oak finish.
Two gold-plated input terminals for bi-amplifier are attached, and metal spike legs are attached.
