Commentary
A 3-way speaker system that uses a concave unit.
A 20 cm cone woofer with radial edge and concave diaphragm is mounted in the low range.
By using the concave type, radiation efficiency is the peak and dip of the crossover frequency.
The mid-range is also equipped with a 10 cm cone-type squaker that adopts a concave type.
A 3 cm dome type tweeter using the ES edge is mounted in the high range.
Equipped with a level control that can switch the middle range to 3 levels.
The enclosure uses a pressure balance system.
The pressure balance system is designed to maintain the balance of internal pressure by allowing only unwanted vibrations outside the audible band to escape from the baffle port, thereby reducing the hermetic enclosure and the bus-ref-type boumey.
