Commentary
A 3-way, 4-speaker system consisting of one 30 cm woofer, one 9cmx29cm horn squaker with an opening, and two 5 cm horn tweeters designed with special consideration for linearity.
The enclosure is a bass reflex system using two pipe ducts, and the inside of the duct is filled with sound absorbing material to eliminate unnecessary low-frequency sounds.
The two tweeters are arranged horizontally to improve the directional characteristics.
The skoker and tweeter levels can be independently adjusted.
The net on the front is a synthetic resin mesh that can be removed.
