Commentary
Delta-olefin A three way speaker system that uses a diaphragm.
In the lower range, a 28 cm cone woofer using delta olefin for diaphragm and dust cap is mounted.
A 4-layer voice coil and cap-toon voice coil bobbin are used to increase the allowable input.
The mid-range is equipped with a 10 cm cone type skoker using delta olefin as well as low-range.
Mutual interference between units is reduced by storing in an independent sealed box with an internal volume of approximately 1L.
A 2.5 cm soft dome type tweeter is installed in the high range.
The diaphragm is based on a special chemical fiber with uniform fiber thickness, improving efficiency by approximately 2 to 3 dB compared to conventional soft dome diaphragm.
It is equipped with independent level control for middle and high frequencies.
