Commentary
A speaker system designed to reproduce the original sound field space with a large scale as it is in real and live.
A 12-inch unit is used for the low band, a 6-inch unit for the middle band, and 16 inch units for the high band.
In addition, the response within the operating range of each unit is made uniform, and the time characteristics are made constant to compensate for the difference between upper and lower characteristics in the normal vertical high-pass driver.
This energy control and time control make it possible to reproduce a three dimensional sound field in which the entire space is richly reverberated.
The MQ 107 equalizer is indispensable for adjusting the speakers.
The enclosure is divided into two parts : a tweeter column and a base cabinet.
The tweeter column was made of solid oak or walnut material, and the base cabinet was made of high density particle board with oak or walnut finish.
