Rare vintage SONY SS-G3 from 70's. All original drivers are alnico and in good working condition, they come with grills and wooden base. Please check link for spec and details.
SS-G3 3WAY SPEAKER SYSTEM ¥
68,000 speaker system in 1977, Sony launched. Became a best seller on the market in 1976 in the previous year SS-G7
as a brother machine, SS-G5, SS-G3 (¥ 48,000) was released in 1977. This means that in the in the "G Series"
comparable to the models between, but for the size of the mounted unit and price, shop was at that time best seller in its class
of Maha NS-690 Ⅱ rivalry to (¥ 69, 000) I can ask as well. Had been adopted in G7 one of the features of the G5 was "PLUMB IN LINE method". Improvement cheat the localization of the front-rear direction woofer unit is come out before order, the sound source position the equivalent of all the units squawker, such as tweeter and those aligned to the vertical line, three units the center in baffle surface Inline way lined up in a row are aligned formula had been taken. Straight cone of 60 ° half apex angle of 30cm diameter, was blended with carbon, woofer unit of pride Sony was CARBOCON unit. Starting from the development of a paper machine easier the cone paper, and paper making method, molding, heat treatment and what often is added until, subjected rib corrugation concentric, rigidity CARBOCON unique internal loss and height are both It was corn unit that is. Also to determine the shape, (space of the Apollo program such as NASTRAN in development, computer technology and programs were used in order to elucidate the mechanical behavior of the complex shape of the spacecraft system) had been applied. The magnetic circuit, very powerful, ranging from 112,500 Maxwell total magnetic flux, and Alnico magnets the magnetic circuit, and in which in addition to the T-shaped pole, using special steel material (FC material), suppressing the generation of harmonic distortion was. The frame, enhanced rigidity by strongly stay part, thickening the outer periphery, is provided on the outer periphery of the back ribs of many more were adopted Asumi die-casting frame. Mid-range, was equipped with a cone type of 8cm diameter employing a balance drive type. Than cone type normal units of form that has a large center dome, was to reduce the effective area, the piston luck faithfully as Ru> can a cone paper in order to differential, we focus on the position and drive point of the voice coil to the cone paper The unit was subjected to improvement Te was. The magnetic circuit, T type and Paul ferrite magnet is adopted, linearity was increased. The Mille is Dorenji, Nick piston motion is possible with high linearity up to 5.5kHz bandwidth of charge, 10 in fact it had the characteristics of enough to cover up to approximately kHz. Tweeter, with domed 2.5cm diameter, and as it is molded integrally titanium foil 20 microns thick, diaphragm, was made possible accurate piston Nick motion to 20,000 Hz. It was what the system was also considered firm. Thick 1.5mm Orient core similar to SS-G7 to the woofer using a inductor suppressed to 0.2Ω or less resistance by winding a conductive wire, further, in order to prevent the effects of resonance between lines in the special resin It was fixed firmly. In addition, the condenser, the characteristics superior in sound quality internal loss is small we were using the metallized film capacitors with. The bass reflex enclosure system, a particle board by Kara pine 18mm thick front baffle, its had been called 18mm thick high-density particle system conifer Bo on the surface of other, and stronger. The baffle surface, it was adopted Sony's own "AG board". The "AG board", unnecessary from the baffle board in order to reduce the phenomenon of reflection to get a negative impact on the direct wave, reflected wave is scattered increments groove aspect of countless baffle surface in what was to be "Accuusticcal Grooved Board It was short for (Acoustic Pharmaceutical Gurubudo board) ". In addition, in order to not drop the intensity of the baffle plate while realizing the close proximity of the midrange and tweeter desirable sound quality on To~ui I was attached to the baffle surface and unites the unit board mid-range and tar. The SS-G3, stand WS-G5 dedicated were provided sold separately. Against a solid heavyweight weight of 13.5kg With those, SS-G5 had come to be played in a floor type the same reason, use it. As described above, the Sony got a high reputation in the SS-G7, SS-G5 was built up in order to series of under the name of G was intermediate model. Can be thought of as a scale-down of the G7, but inherited the technical content firmly, firmly bass I had a sound that is balanced to support the base.
