Commentary
This is a speaker system that expands the low-frequency reproduction capability without changing the tweeter common to the A series.
Three 20 cm cone type woofers are installed in the lower range to increase the area of the diaphragm.
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.
Equipped with a 17.5 cm cone type squaker in the middle area.
The diaphragm uses a mica-mixed polypropylene cone that is injection molded in the same way as the woofer to 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.
The enclosure is reinforced to withstand the vibration and sound pressure of the woofer.
The cabinet has been given a real wood finish by Santos Rosewood for a natural sound, and the four vertical corners are made of the same solid board with rounded edges.
It uses a terminal for bi-wiring.
Spikes and insulators are included.
