Commentary
A speaker system incorporating diatone technology such as a distributed resonance structure.
A 30 cm cone type woofer is installed in the low range.
This unit was developed based on the Woofer unit PW-125 of the monitor speaker 2S-305. The magnetic circuit uses a strong Alnico 55 φ x35 magnet for moderate damping and high efficiency. For the cone paper, a corrugation cone shape is adopted in order to eliminate minute / s resonance, and sound quality in the middle and low frequencies is improved.
The edge uses a roll shape. The non-linear distortion is improved by making it asymmetrical without making it into a perfect semicircle. In addition, the sound quality is improved by using Cross Edge with viscoelastic coating.
A 12 cm cone type squaker is installed in the middle range, and a 2.3 cm dome type tweeter is installed in the high range.
For the coil of the network section, a super-large coil newly developed especially for the highest grade system is adopted, and the strain generated from the network is reduced.
There are separate level controls for the mid range and high range.
This level control allows three levels of switching.
The enclosure uses a sealed system and the internal structure uses a unique distributed resonance type.
This structure minimizes cabinet vibration with a well-vetted rigid joint structure and special distributed reinforcing bars, and by distributing resonance modes, it reduces box ringing when the cabinet is highly resonant in a specific band.
