Commentary
3-way speaker system pursuing high sound quality to orthodox using Alnico magnet and natural materials.
31.5 cm cone type Woofer using Kurtmueller's corn paper is carried in low-pass.
12 cm corn type squawker is carried in the mid range.
Corn paper made by Kurtmueller company is adopted for this unit as well as Woofer. In addition, Alnico Magnet is adopted as a magnetic circuit, and by adopting a ring type in which a hole is drilled in a pole piece in order to eliminate the back pressure in the magnetic circuit, the diaphragm has obtained excellent response with extremely linearity .
3.5 cm soft dome type tweeter is carried in the high region.
In order to match the sound quality to the middle and low frequency diaphragms using natural materials, diaphragm laminated with Hakurei's silk with thin curtain rubber is adopted.
The network section is designed considering the arrangement of high, medium, and low range network elements, eliminating mutual interference. Moreover, by adopting caulking connection that does not use solder for the wiring connection part, it also prevents sound quality deterioration by sealing with the adhesive.
In addition, we are trying to further improve the sound quality by high-quality sound condensers and coils.
In the cabinet carefully selected high-density materials of beautiful coniferous coniferous trees are adopted.
In addition, in order to realize a cabinet with high strength, the cleavage method which joins using the pile (cleat) is adopted as the front baffle, and furthermore, all of the six sides are brought to a high pressure of about 1 ton by the original high speed high pressure consolidation method It is instantly assembled. In addition, in this construction method, we do not perform heat treatment which makes the adhesion surface fragile, so we have realized a highly reliable cabinet.
The unit layout adopts the new G line unit layout by the sound intensity method, realizing a natural sound field. Furthermore, by adopting the super elliptical baffle, directivity is improved with clear sound image localization.
Input terminals compatible with bi-wire ring connection are adopted, and interference by counter electromotive force can be suppressed.
