All parts operate normally. About the product DIATONE DS-A5 ¥217800 (tax included) Released around 1995 This speaker is the second in the series of speakers released to commemorate the 50th anniversary of the Diatone Workshop. It is equipped with a 13cm cone-type woofer for the low range. The diaphragm is made of aramid cloth. This diaphragm uses aramid, an aromatic polyamide organic fiber with high strength and moderate internal loss, as the cone material, and by using a two-layer structure, it eliminates the binders such as epoxy resin that were previously used, making it lighter. The high range uses a 4cm cone tweeter. The diaphragm uses a newly developed aramid cloth cone, and by using the same material as the woofer, the speed of sound is uniform, creating a two-way design with equal sound velocity. The network section uses pressure-applied wiring with oxygen-free copper sleeves to prevent distortion, and low-distortion coils with laminated orient cores. The enclosure uses a new-structure maple top enclosure. This method is based on the technique of making stringed instruments that actively make use of the resonance of the wood, and the structure uses baffle plates and back plates to cover the front and back of the same board, making use of the resonance of both boards using the simplest joining method, the “potato joint”. In addition, the top panel is made of Canadian maple, which has a high density and beautiful resonance, in order to improve the texture of the high-pitched range, where many of the overtones that determine the tone of the instrument are distributed. By making the center of the top panel thicker, we have increased the rigidity and controlled the resonance.

A speaker system developed as a music reference for high-sampling digital audio. A 30 cm cone type woofer is installed in the low range. Aramid honeycomb is used for the diaphragm. Aramid fiber is an aromatic polyamide long fiber with high strength, high elasticity, light weight and moderate internal loss. This material is used as a skin material and H. D. (high damping) alloy is sandwiched as a honeycomb core. 3-axis woven aramid fiber is used for the edge that supports the diaphragm. By demonstrating strength in all directions, dispersion resonance at high input is suppressed. In addition, by entwining special damping agent into the fiber, high-order natural resonance of the diaphragm and edge itself is suppressed, and the texture is improved. The magnetic circuit is equipped with A. D. M. C. -m (Advanced Magnet Circuit-music) to improve response to input signals. The mid-range features a 6 cm dome mid-range. B for the diaphragm4Uses C Pure Boron. B4C has a high specific elastic modulus second only to crystalline diamond and moderate internal loss, and is used in the D. U. D structure which is the diaphragm structure of the Diatone tradition to obtain excellent response. B4C has a very high melting point of 2,450 ?, so it was said that it was impossible to mold with conventional technology. However, Diatone has solved this problem by its unique plasma spraying method. The magnetic circuit uses a hybrid D. M. with a highly rigid frame structure. The plate portion is directly fixed to the baffle plate and wrapped in aluminum alloy stings to improve the S/N feeling. A 2.3 mm dome type tweeter is installed in the high range. B for Tweeter as well as mid-range4C pure boron boron diaphragm has a D. U. D structure, enabling high-speed playback with less signal transmission loss. Hybrid D. M. is used for the magnetic circuit and frame structure, enabling high-quality playback. The network section employs an independent power supply system that eliminates mutual interference between units, and a distributed configuration to suppress current modulation caused by interference between network elements. The tweeters high-pass filter uses carefully selected elements with particularly excellent high-frequency characteristics. It uses uncompromising parts such as capacitors with low tan ? and unique air-core coils. In addition, it uses crimping wiring without soldering to increase signal purity.

Manufacturer and model number DIATONE DS-20000 Accessories Stand The saran net is not included. Condition / Maintenance ?About the product DIATONE DS-20000 & DK-20000 ? We have completed a DS20000 that has been carefully restored and maintained in our store. This unit has had all of the individual speaker units removed, The enclosure and stand were painstakingly piano mirror coated. Even the back of the enclosure was painted with a mirror piano finish. The speaker frames and screws are of course beautifully dressed, The speaker frames and screws have been carefully brushed up to the smallest detail to create a superb condition that is as good as new. In addition, the boron diaphragm used in the tweeter was replaced with one that we have in stock, albeit in small quantities. The boron used in this unit has an ultra-wide range reproduction capability comparable to B&Ws diamond tweeters. It is an excellent product that can reproduce the sources with a large amount of information in recent years, such as high-resolution audio, without leaving any room for error. In addition, the woofer edges have been carefully softened to ensure a long-lasting, stress-free sound in each bandwidth. The woofer edges have been carefully softened to ensure stress-free sound in each frequency range for many years to come. The following is a quote from the website below. This speaker system was developed by Diatone Workshop using a number of acoustic and woodworking technologies. The low-frequency range is equipped with a 10.6in cone woofer using aramid honeycomb cones. Aramid fiber is an aromatic polyamide long fiber that has high strength and elasticity properties as well as light weight and moderate internal loss. By using a special matrix resin that is a special blend of aramid fiber and flexible resin for the skin material of honeycomb cones The honeycomb diaphragm is bonded to the core to form a honeycomb structure diaphragm. The edges are made of triaxial aramid fibers that exhibit uniform strength in all directions, The edge section is made of triaxially woven aramid fiber, which exhibits uniform strength in all directions, to realize a piston motion with excellent linearity and minimal rolling. The A.D.M.C.-m (Advanced Magnet Circuit-music) magnetic circuit is used in the magnetic circuit to improve response to input signals and stabilize operation against transient response, The M.M.C.-m (Advanced Magnet Circuit-music) magnetic circuit is designed to improve the response to input signals, stabilize the operation against transient response, and stabilize the operation against AC magnetic flux in the time domain. Furthermore, the air flow generated by the vibration of the diaphragm is also focused on, The back of the diaphragm, which radiates into the cabinet, has been studied in detail to improve the audible S/N. The midrange is composed of a B4C diaphragm, a B4C loudspeaker, and a B4C loudspeaker. The midrange is equipped with a 3.0in dome midrange using a B4C diaphragm. B4C boasts the second highest specific modulus after crystalline diamond, and also has moderate internal loss due to its non-metallic nature. Since this material has a high melting point of 2,450°C, it is formed by DiaTones proprietary plasma spraying method, By precisely controlling this manufacturing method, a large-diameter B4C diaphragm is realized. The diaphragm is made of a D.U.D. structure with an integrated voice coil bobbin to ensure excellent linearity with respect to input signals. The high frequency range is equipped with a 0.9in dome tweeter using a B4C diaphragm. Like the midrange, this unit uses a D.U.D. structure with an integrated voice coil bobbin. The magnetic circuit uses the D.M. (direct mounting) method, in which the plate is directly attached to the baffle plate, The large-diameter copper alloy sub-frame thoroughly suppresses unwanted resonance. System: 3-way, 3-speaker, sealed, bookshelf, magnetically shielded (EIAJ) type Low-frequency unit: 10.6in cone type Unit for mid-range: 3.0in dome type Unit used for high frequency: 0.9in dome type Rated impedance: 4?

It has a large body for a bookshelf type. Black is the only color available. The bass-reflex port designed on the back is relatively large in proportion to the size of the shape, and it provides a sense of low-frequency volume similar to that of a tall-boy type. The front baffle surface is made of 36 mm thick Finnish birch wood. It is hard, has moderate tenacity, and has high damping power. The system is equipped with an original unit developed in-house. The first thing that deserves special mention is the diaphragm. The newly developed material is called “NCV-R,” which is made of carbon nanotubes and several types of resin, and despite being a resin material, it has a propagation speed that exceeds that of titanium and an internal loss equivalent to that of paper. This material is used for both woofers and tweeters to express a coherent sound quality. (Adapted from Dynamicaudio 5555, Mr. Amanos blog) Shipping from Japan with Tracking Number & Insurance.

The sound quality is good for jazz, classical music, and slow ballads. At low volume, the bass is subdued. When the volume is turned up, the bass increases and the scale seems to expand. This is a pure sound source, and it is possible to change the sound to your liking if there is an equalizer on the unit side. Shipping from Japan with Tracking Number & Insurance.

A speaker system developed as a music reference for high-sampling digital audio. A 30 cm cone type woofer is installed in the low range. Aramid honeycomb is used for the diaphragm. Aramid fiber is an aromatic polyamide long fiber with high strength, high elasticity, light weight and moderate internal loss. This material is used as a skin material and H. D. (high damping) alloy is sandwiched as a honeycomb core. 3-axis woven aramid fiber is used for the edge that supports the diaphragm. By demonstrating strength in all directions, dispersion resonance at high input is suppressed. In addition, by entwining special damping agent into the fiber, high-order natural resonance of the diaphragm and edge itself is suppressed, and the texture is improved. The magnetic circuit is equipped with A. D. M. C. -m (Advanced Magnet Circuit-music) to improve response to input signals. The mid-range features a 6 cm dome mid-range. B for the diaphragm4Uses C Pure Boron. B4C has a high specific elastic modulus second only to crystalline diamond and moderate internal loss, and is used in the D. U. D structure which is the diaphragm structure of the Diatone tradition to obtain excellent response. B4C has a very high melting point of 2,450 ?, so it was said that it was impossible to mold with conventional technology. However, Diatone has solved this problem by its unique plasma spraying method. The magnetic circuit uses a hybrid D. M. with a highly rigid frame structure. The plate portion is directly fixed to the baffle plate and wrapped in aluminum alloy stings to improve the S/N feeling. A 2.3 mm dome type tweeter is installed in the high range. B for Tweeter as well as mid-range4C pure boron boron diaphragm has a D. U. D structure, enabling high-speed playback with less signal transmission loss. Hybrid D. M. is used for the magnetic circuit and frame structure, enabling high-quality playback. The network section employs an independent power supply system that eliminates mutual interference between units, and a distributed configuration to suppress current modulation caused by interference between network elements. The tweeters high-pass filter uses carefully selected elements with particularly excellent high-frequency characteristics. It uses uncompromising parts such as capacitors with low tan ? and unique air-core coils. In addition, it uses crimping wiring without soldering to increase signal purity.
