Commentary
An improved and developed speaker system based on EV-Four.
A 30 cm cone type woofer is installed in the low range.
Special foamed resin is used for the edge part to increase linearity of large amplitude.
A 15 cm cone type skoker is mounted in the middle area.
This unit has a particularly low fo, one octave below the crossover point, to make the response in the used band as flat as possible.
It is mounted in a closed, independently braked enclosure to eliminate interference with the woofer.
A 6 cm cone type tweeter is installed in the high range.
The gap between the voice coil and yoke is filled with viscous material.
It is equipped with a level control that allows you to adjust the middle and high levels independently.
The enclosure has a four sided walnut finish.
