Commentary
3-way bookshelf speaker system.
A 25 cm cone type woofer is installed in the low range.
The diaphragm is made of a base of kraft pulp with special vegetable fiber and has moderate internal loss. The cone shape is shallow to reduce split vibration.
110 mm φ magnet is used for the magnetic circuit.
The 13 cm cone type skoker is mounted in the middle area.
The voice coil bobbin uses an aluminum bobbin with good propagation characteristics and a wave-shaped free edge to obtain sound quality. In addition, a dome-shaped center cap made of vegetable fiber coated with special resin is used to smooth the connection with the tweeter.
A newly developed 6.5 cm cone type tweeter is mounted in the high range.
A 17 mm φ aluminum direct radiator is used in the center of the cone paper to improve resolution and directivity in the high frequency range, and CCAW (copper coated aluminum wire) is used for the voice coil to reduce the weight of the vibration system.
The rear part of the diaphragm has a sealed structure, and the connection with the skoker is improved by the dumped ported back cavity system filled with dump material.
The network is a parallel type using an E-type ferrite core inductor, which generates little distortion and minimizes phase displacement even at large inputs.
The enclosure has an internal volume of 46 liters and is designed as a bass reflex with a pipe duct.
By using high-density boards for baffle plates and three layers of high-density boards for side plates and top plates, moderate internal losses are obtained.
