Commentary
This is a 2-way speaker system that uses CARBOCON for the diaphragm.
A 25 cm cone type woofer is installed in the low range.
The diaphragm is made of CARBOCON with improved rigidity by mixing carbon fibers with cone paper, and resonance is suppressed by mixing carbon fibers radially into the rubber edge.
A 3.5 cm dome type tweeter using a newly developed laminate diaphragm is mounted in the high frequency range.
A low-distortion magnetic circuit has been adopted to reduce odd-order harmonic distortion in the mid - and high-frequency range, enabling clearer sound reproduction.
The Network Division focuses on selective selection of parts and simplification of configuration, and improves transient characteristics and phase characteristics.
The enclosure is hermetically sealed, with sealing and packing material at critical points to keep the air from inside and outside, and the baffle plate and back plate are reinforced effectively to disperse plate vibration.
A dark-tone net with a aluminum sash on the side is used for the Sa RUNNET.
