Description


Please thank you.

Speaker system rather than to pursue a high-rigidity only high-elasticity and optimal ロスファクター in the higher dimensions, fusing ハイブリダート thought.

Woofer
Low with a 31 cm cone type woofer in the region.
Adopt a アラミッドハイブリッドハニカム vibration plate vibration plate, table skins aramid hybrid FRP was adopted cellulose fibers of skin behind skins.
Aramid hybrid FRP adopted table skins is the イントラプライ structure of the organic fiber aramid and inorganic amorphous silica fibers. Aramid fibers combines high strength and high elastic, with low density and internal losses, moderately aromatic polyamide fiber, fiber itself has high rigidity is amorphous silica. Try skin material thing to ハイブリッドウィービング woven textile イントラプライ structure of the two, having a high ratio elastic ratio and optimal ロスファクター. Cellulose fibers of skin was hired back skin is the skin material made from cellulose fibers superior internal losses.

Employed R. S. frame high rigidity to the frame structure, in 8 point pinned into an enclosure is mounted firmly.

Mid-range speaker
Medium range with 10 cm cone type mid-range speaker.
Cone of vibrating plate adopts organic fiber aramid and inorganic fibers PAN-based high strength carbon fiber with イントラプライ structure and イントラプライ hybrid vibration plate.
Using polyacrylonitrile PAN-based high strength carbon fibers are extremely high ratio elastic ratio.

センターダイアフラム vibration plate adopted Titan balance high-modulus and ロスファクター by surface hardening treatment for Titanium S. R. dome.

Adopt a tangential edges at the edge.
This edge, characteristic flattened and reduced strain for improved responsiveness by coating with special material two tangential cross-a laminated structure for the resonance control.

For the higher rigidity of the unit frame woofers as well as to adopt R. S. frame.

The tweeter
High area, with 2.5 cm dome tweeter.

Diaphragm adopts Titan combines high hardness and internal losses, moderately, and surface hardening treatment for Titanium S. R. dome.

ダイヤトーン your own D.M.( direct mount to the unit structure ) construction.
With the approach framed the part of magnetic circuit in the D. M. structure d. M. 構造 で は 磁気 回路 の 一部 を フレーム 化 し バッフル 板 に 直接 マウント する direct mount baffle plate, excellent magnetic characteristics of low carbon soft hardwood conducts acts as a conventional frame.

Network
Employed crimp wiring scheme in network wiring system, electrical wires together through the sleeve, but we improved acoustic properties, eliminating the dissimilar metal boundary strain caused by soldering, crimping the thing.

Eliminate the cause of recruitment, quality divided into two structures with separate elements for woofer caused great flux modulation. Adopted oxygen-free copper wire to orient laminated core and wire coil.

The enclosure
Large oval-shaped 4 clinched around four sides have rounded adopted サイドラウンドバッフル, sound wave diffraction phenomenon improved spread of sound image and sound.

Analysis technology ダイヤトーン and a modal analysis of your own enclosure structure is adopted.
