Commentary
A compact speaker system that uses a magnet shield to prevent magnetic flux leakage.
A 20 cm cone type woofer is installed in the low range.
High input resistance and accurate piston motion are realized by the adoption of urethane rubber in the edge part. In addition, the dust cap is made of material subjected to special damping treatment with butyl to improve medium and high range components.
A 5 cm cone type tweeter is installed in the high range.
A special rubber damper is used to cut unnecessary low frequencies, and a treatment cap with excellent high-frequency characteristics is used for the center cap to achieve high-frequency playback with good clarity.
It is equipped with a 1.6 cm dome type super tweeter for super high frequency band.
In order to prevent the leakage of magnetic flux from the speakers, which adversely affects the TV screen, we have adopted a magnet shield system in which anti-magnetic magnets are attached to the woofer and tweeter. In addition, in consideration of the adverse effect of TV magnetism on the speakers, we have also examined the position and orientation of network coils.
In addition to the normal HiFi position, it is equipped with an AV equalizer with a sound quality correction function for visual software.
The enclosure is a bass reflex type using a highly rigid distributed resonance structure.
