SANSUI AA-100

Commentary

This speaker system improves the reproduction of music by optimally matching the newly developed speaker unit with the enclosure.

A 20 cm cone type woofer is installed in the low range.
The vibrating plate is made of kraft pulp with an appropriate mixture of special vegetable fiber and animal fiber. The diaphragm is shallow to improve directional characteristics and minimize distortion due to split vibration.
90 mm φ ferrite magnet is used for the magnetic circuit.

A 6.5 cm cone type tweeter is installed in the high range.
An ultra-thin aluminum direct radiator is used in the center of the diaphragm to improve sound quality in the high frequency range and improve directivity.
CCAW (Copper-Covered Aluminum Wire) is used for the voice coil, and a dumped ported back cavity method is used with moderate damping on the rear surface of the diaphragm to keep sound connection natural.

A newly developed sealed type I-type ferrite core is used in the network section to prevent saturation and minimize phase displacement for large inputs.

The enclosure has an internal volume of 37 liters and uses a bass-reflex system with a pipe duct.
For the baffle plate and back plate, particle board with moderate internal loss is used, and for the side plate, high-density particle board with three layer structure is used to increase the strength.
