Victor SX-500DE / Luxman M-05

• VICTOR SX-500DE Dolce Eterno • 175,000 yen (1 set of 2 units, around 1999) The SX-500 series bookshelf type speaker system that newly adopts the Oblidome. The 2.5cm oblate soft dome shape tweeter is carried in the high region. The double-blade silk oblidome is adopted as a diaphragm. In this diaphragm, the top which was in the center of the dome until now is arranged above the center. As a result, the directivity of the sound is further expanded to realize a rich high-frequency sound field. The Alnico magnetic circuit is adopted as a magnetic circuit, and the driving force is raised more by performing annealing treatment. The 20cm corn type Woofer is carried in low-pass. The highly elastic pulp corn for rigid bass reflex is further adopted as a diaphragm by the special manufacturing method based on the Kurt Mueller cone. Moreover, in order to sound this Woofer better, the edgewise voice coil excellent in driving power is adopted, and the transient characteristic is raised and the wide play range is acquired. Furthermore, the spider suspension made from the US material with good linearity and high durability enhances the reproduction capability of minute signals. The Alnico magnetic circuit to which annealing processing was given is adopted as a magnetic circuit. Carefully selected parts such as a film capacitor with excellent high frequency characteristics, an oxygen-free copper wire, an air core coil, and a brass machined input terminal for banana plugs are used in the...
