FOSTEX SVA20
¥ 38,000 (1 unit, around 1989)
Commentary
A 2-way active speaker system incorporating a power amplifier into the SV20.
The magnetic circuit uses a repulse type magnetic circuit with very little magnetic leakage to the outside.
This eliminates the impact on cathode ray tubes and other products.
A 13 cm cone type woofer is installed in the low range.
A multi-layer cone unique to Fostex is used for the diaphragm.
A ring-type RP tweeter is installed in the high range.
The enclosure has a unique curvilinear form. It is made of extra-thick special foam molding with a thickness of 5 cm using advanced molding technology. There is no noise or insufficient strength that can be seen with resin molded products.
A bass reflex system is adopted for the internal structure, and a special rubber damper with high anti-vibration ability is installed in the rear part to enable voluminous low sound reproduction.
There was a special speaker stand SF450 sold separately.
This stand can be set to a height of approximately 45 cm from the floor or can be fixed by swinging the speaker from side to side.
