Electro-Voice Interface:1II
¥ 50,000 (1 unit, around 1979)
Commentary
A low-cost speaker system from the Interface Series that uses the same parts as the high-end model.
A 20 cm cone type woofer is installed in the low range.
The high-frequency band is equipped with a 3.8 cm dome type super dome tweeter, which is the same as the high-end model.
This unit uses a large magnet and a high-efficiency magnetic circuit in which a magnetic fluid is sealed in the voice coil gap, realizing efficiency two to four times higher than that of the conventional dome type. The diaphragm is made of two layers of phenol resin.
In addition, an acoustic lens of acoustic form is mounted on the front of the dome, which greatly improves the directivity characteristic in the ultra-high range.
The enclosure has a bass-reflex structure.
