Commentary
Interface : An interface series speaker system that is an improved version of C.
A 25 cm cone type woofer is installed in the low range.
The mid-range includes the Bent Mid-range II, a 16 cm cone mid-range with the same diameter as the Interface : DII.
This unit is constructed by applying the "interface type optimum phase inversion system" of the woofer division, and expands the low-frequency range. In addition, the efficiency is improved by using the huge magnetic circuit equivalent to the woofer. This improves the quality of the mid-range with the crossover frequency which is one octave lower than the usual three way system.
It is equipped with a 3.8 cm superdome tweeter equipped with an acoustic lens in the high range.
This unit uses a large magnet and a high-efficiency magnetic circuit in which magnetic fluid is sealed in the voice coil gap, resulting in efficiency two to four times higher than that of the conventional dome type. The dome is made of two layers of phenol and resin.
The front of the dome is equipped with an acoustic lens of acoustic form, which greatly improves the directional characteristics in the ultra-high range.
The enclosure is designed with a bass reflex.
SEQ equalizer is included.
