SANYO SX-Z3000 (1990)

Brand: Sanyo (Fisher)

Model: SX-Z3000 (STE-555)

Year: 1990

The main feature of the SX-Z3000 from Sanyo is the Twin-Drive woofer system. This is a completely new type of speaker using a completely new method that uses two drive units installed in front and behind of the the flat diaphragm to drive-it in a push-pull manner. When one drive unit pushes out the diaphragm, the other one pulls it in, and vice versa. This new woofer design uses drive energy more efficiently equalizes uneven magnetic flux density, equalizes the damper's diaphragm control force, and eliminates rolling phenomena, resulting in significantly improved linearity. This method makes possible to achieve lower distortion and less heat generated. For maximum rigidity all the elements are mounted in a aluminum die-cast frame. The cabinet is made of high-density particle board with rounded edges for less diffraction. As a result of Fisher being owned by Sanyo another version was sold as Fisher STE-555.
