Commentary
A speaker system designed to improve the transient characteristics of the entire system.
A 25 cm cone woofer with radial edge and concave diaphragm is mounted in the low range.
The mid-range is equipped with a concave 10 cm cone skoker.
A 3-cm dome type tweeter is installed in the high range.
It is equipped with a continuously variable level control for high frequencies.
In order to prevent transient deterioration due to resonance of the enclosure, A / D / solid material is used for the front baffle.
This A ・ D ・ Solid material is a high-density molding material that is molded using synthetic resin technology. It has properties closer to stone than wood. This material has a specific gravity three to four times that of plywood. Internal loss is equivalent to that of plywood. By using this material for the front baffle, boxiness is reduced.
