Commentary
This speaker system aims at three dimensional localization of acoustic natural tone and excellent sound image.
99.9999% high purity oxygen-free copper is used for the voice coil of woofer and tweeter.
Compared with conventional tough pitch copper, the ability to transmit music signals that change from moment to moment is greatly improved.
A 20 cm cone type unit is used for the low range.
By adopting the advanced bipolar cone diaphragm, smooth roll-off characteristics with less peaks and dips are realized.
The magnetic circuit uses an MDCT with an aluminum ring mounted inside the magnet, greatly reducing non-linear strain and magnetic strain.
A soft dome unit of 2.5 cm is adopted for the high range.
It uses a pure silk diaphragm made of carefully selected pure silk fabric and kneaded with unique coating technology.
It uses an acoustic stabilizer that reproduces a low range full of dynamic feeling, and a gold plated brass scraping terminal for banana plug.
