DIATONE DS-V3000
¥ 450,000 (1 unit, released in November 1990)
Commentary
V-series speaker system with large pure boron diaphragm.
A 30 cm cone type woofer is installed in the low range.
Super Aramid Honeycomb is used for the diaphragm of this unit. This honeycomb core is made of Super Aramid, which has achieved a large increase in elastic modulus of 40% compared with conventional aramid fiber, and newly developed aluminum alloy, which suppresses vibration, is sandwiched. This honeycomb core realizes high rigidity and excellent vibration damping characteristics. In addition, it is supported by the edge of 3-axis woven aramid, which demonstrates strength in all directions, and realizes piston motion with less rolling.
The A.D. M.C. -m (Advanced Magnet Circuit-music) is used for the magnetic circuit, and the A.D. M.C. theory is applied to actual music waveforms to improve the response to input signals, stabilize the operation of the magnetic circuit against transient response, and stabilize the AC magnetic flux in the time domain. This improves the reproduction capability. The Woofer Unit is equipped with an external magnetic type A.D. M.C. -m.
The mid-range features a 7.5 cm dome mid-range.
This unit contains B, which has excellent properties.4C is formed into a large diameter of 75 mm by plasma spraying and used to realize excellent medium range regeneration. In addition, this unit adopts the Diatone traditional D. U. D. and D. M. structure to realize highly responsive regeneration.
In the mid-range, the magnetic circuit is equipped with Alnico internal magnetic type A. D. M. C. -m.
B for the high range as well as the mid-range4It is equipped with a 2.3 cm dome type tweeter that adopts a C diaphragm.
The tweeter also adopts the D. U. D method.
A 3-division network is used for the network section to eliminate mutual interference between units.
The enclosure has a polyurethane paint finish of walnut real wood material.
In addition, the round shape of the front baffle prevents the diffraction effect of sound.
