ACOUSTIC ENERGY AE1 Signature
¥ 440,000 (one set of two, around October 1996)
Commentary
Signature series speaker system corresponding to high-grade special tuning machine.
The Signature Series uses strictly selected units.
The network section has been newly designed with high-quality elements. Premium grade high-pressure polypropylene capacitors and glass-like enamel winding resistors are used, and pure silver cables are used for internal wiring.
In addition, the pair matching of the left and right channels has an error of less than 0.25 dB.
The enclosure uses a unique sound absorber system with a newly developed porous material with high internal loss and high rigidity attached to the inner wall to increase the strength, effectively cancel standing waves and increase the weight by approximately 40%.
The exterior has a piano rosewood finish with a clear lacquer.
A 9 cm cone type woofer is installed in the low range.
The diaphragm is made of aluminum alloy and has a three layer structure with electrolytic coating on both sides. This realizes both high rigidity and necessary internal loss in spite of its light weight. The voice coil also functions as a heat sink, suppressing the temperature rise of the voice coil and providing excellent linearity for large input.
A 2.5 cm hard-domed tweeter is installed in the high range.
A magnesium alloy dome is used for the diaphragm, and an aluminum voice coil plated with copper is directly heat-fused to the dome to improve the input resistance and realize excellent high-frequency reproduction.
There was a special speaker stand as an option sold separately.
