Commentary
A speaker system in which a unit developed for the A series is arranged in a cabinet with real wood and veneer finish.
A 17.5 cm cone type woofer is installed in the low range.
The diaphragm uses polypropylene cone mixed with mica by the newly developed injection molding method. This manufacturing method can increase the strength around the voice coil, suppress resonance caused by the bell phenomenon, and expand the dynamic range and reduce distortion.
A 2.5 cm hard dome type tweeter is installed in the high range.
A titanium dome has been adopted for the diaphragm, and the split vibration that causes the muddy sound and the sharpness of the ears is solved by utilizing Celestion's unique laser analysis method.
In addition, a Faraday ring is used in the magnetic circuit to reduce distortion and improve efficiency over a wide range.
In addition, the shape of the aluminum die-cast plate is designed to improve the orientation of the instrument.
Each unit uses an aluminum die-cast in which the frame and face plate are integrally molded.
By adopting the shape of the aluminum die-cast face plate and the layout in which the woofer and tweeter are placed as close as possible, we aim to achieve more accurate positional relationship.
In addition, the cabinet has a high quality real wood finish for natural sounding, and the four vertical corners are made of the same solid board with rounded edges.
It uses a terminal for bi-wiring.
The cabinet is managed from the time of cutting out the wood so that the wood grain is a pair of left and right, and each pair is paired.
Also, there were 2 kinds of finishes, cherry wood and Santos Rosewood.
