Product Details DIATONE DS-500 (2 units per set, released in March 1988). A History series two-way speaker system that uses a liquid crystal polymer diaphragm. The diaphragms of both the low and high frequencies are made of a new material, LCP (Liquid Crystal Polymer), making it a two-way speaker with equal sound speed.
When a certain stimulus is applied to LCP, the polymers simultaneously orient themselves, increasing their rigidity, and it has an inelasticity comparable to that of metal. In addition, because it is a polymer material, it also has a large internal loss that is close to ideal. To use this excellent material as the diaphragm, Diatone uses an injection molding method in which polymer is injected at high speed to form a mold. The uniform orientation of the polymer increases rigidity, and the ultra-thin molding improves the specific elastic modulus. The 18cm cone-type woofer is carried in low-pass.This unit has a smaller frame width and no bolts to reduce unwanted radiation from the frame. The 2.5cm dome tweeter is carried in the high region. The tweeter unit achieves high speed by adopting Diatone's unique DUD structure that integrates the diaphragm and voice coil. In addition, the magnetic circuit has a DM structure that suppresses unnecessary vibrations and achieves high rigidity. The frame area has been reduced and the bolts have been eliminated to reduce unnecessary radiation.
Each unit is designed with a magnetic shield using a canceling magnet. The coil of the network section is made of oxygen-free copper.
In addition, the connection method uses a solderless crimp wiring method, which increases the purity of transmission. The front baffle of the enclosure uses a lumber core made of spruce, which has excellent damping characteristics and beautiful resonance and is also used in pianos. In addition, by making it a distributed resonance type, rigidity is increased, and by making all four sides of the baffle round, unnecessary radiation due to the diffraction effect of sound is suppressed.This stand is designed to naturally expand the sound field and is also equipped with an adjuster to keep the speaker perfectly aligned with the floor. Condition Sound output confirmed Enclosure repair and modification. Accessories Saran net Some tears in the saran net have been repaired. Hi, my name is Danny Chou.
