Commentary
An easy-to-use 2-way speaker system developed for natural and powerful playback sound.
A 26.5 cm cone type woofer with a delta olefin diaphragm is mounted in the low range.
By using delta olefin for the diaphragm and dust cap, the characteristics of the material can be utilized, and very simple characteristics can be obtained with almost no harmful high-frequency resonance. It is possible to remove the high-cut filter of the woofer part.
The magnetic circuit uses a 110 φ magnet, capton voice coil bobbin and wire for special coating to improve input resistance.
A 2.5 cm soft dome type tweeter is installed in the high range.
The diaphragm has a high Young's modulus and high internal loss by applying a newly developed special resin blend coating material to a chemical fiber diaphragm with uniform fiber thickness.
In addition, a diffuser designed by applying computer analysis has been adopted to improve directivity.
