Commentary
Two way speaker system.
The woofer is designed with a low dynamic range to reproduce the power of the on-stage.
The cone paper is a shallow type mixed with carbon fiber. The surface is coated with a special acoustic damping agent to increase strength and suppress resonance.
The magnetic circuit is equipped with a ferrite magnet of 156 φ mm, the pole is equipped with a pure copper cap to reduce current distortion, and the voice coil is equipped with a long type that reduces distortion even when Dainyu is strong.
The frame is made of aluminum die-cast to eliminate resonance and is firmly mounted with 8 screws.
A straight-shaped cone paper is used for the tweeter to reduce the weight of the vibration system, and a special adhesive is applied to the cone neck to improve the elongation of the high frequency range.
In addition, the high frequency sound quality is improved by the roll type Cross Edge with good linearity.
The magnetic circuit is a 70 mm magnet, and the frame is made of aluminum die-cast like Woofer.
The enclosure is a finely tuned bass-reflex structure and the ducts are uniquely designed to be folded internally to avoid unwanted mid-sound radiation from the openings.
The enclosure units are arranged symmetrically to clarify the orientation.
The level of the high-frequency range can be adjusted.
