Commentary
A 3-way speaker that uses a pure cross carbon diaphragm and a delta-olefin refined diaphragm.
The vibration plate of the woofer is made of two layers of carbon that are separated by a 45 ° angle. The rigidity characteristic of carbon is exhibited in all directions. In addition, a special epoxy resin is used for the binding material used in cone molding to ensure a large internal loss without damaging the original characteristics of carbon such as high rigidity and light weight, and to eliminate the natural sound of the material.
The Skoka diaphragm uses a delta-olefin refined diaphragm with four times the rigidity by adding an additive compound to delta-olefin.
A magnesium alloy diaphragm is used for the tweeter, and a computer analysis diffuser is attached to the diaphragm to achieve high resolution in a wide listening area.
For the network, we have adopted a concentrated single-point earth by applying amplifier circuit technology and a split type network of Woofer circuit / Squaker / Tweeter circuit to eliminate interference between units and networks and improve sense of orientation.
A rigid anti-vibration material (mixed material of mica and butyl rubber) is filled in the contact part of the Woofer / Scoker unit with the cabinet to protect accurate piston motion from unwanted interference.
