SONY SS-V4

Commentary

A bookshelf type speaker system developed by inheriting the technology of the G series.

A 30 cm cone type woofer is installed in the low range.
As with the G-Series, the diaphragm of this unit is made of CARBOCON, which is light, rigid, and has low resonance sharpness. The cone paper has undergone a special impregnation process, and its shape has been determined from both NASTRAN vibration analysis data and audibility.
The magnetic circuit uses a magnet with a magnetic flux density of 10,000 gauss and a diameter of 120 mm. The combination with a long voice coil realizes a drive with plenty of space.
Aluminum die-cast is used for the frame.

A 4 cm balanced drive type tweeter is installed in the high range.
Natural silk is used for the diaphragm, and by coating it with a special resin developed in-house, it has appropriate rigidity.

In order to improve orientation, the front baffle is equipped with a dual load port with a tweeter, and an AG boat is used for the baffle plate to prevent interference between direct and reflected waves and sharp directional characteristics.
The internal volume of the enclosure is 54L.

There was a speaker stand sold separately.
