Commentary
This compact 3-way speaker system was developed using Lordi's original speaker technology.
It is equipped with a 20 cm cone type woofer that uses ギャザードエッジ for the low range.
It is equipped with a Lo-D Actuator (low distortion magnetic circuit) for suppressing distortion and seeking clear sound.
The voice coil bobbin is made of a new material, aromatic polyamide fiber, and the voice coil is made of heat-cured self-welding wire. This greatly improves input resistance and realizes low-frequency playback with good linearity from large input to small input because the fiber bobbin does not apply electromagnetic braking.
A 2.5 cm dome type tweeter with titanium diaphragm is mounted in the high frequency range.
In addition to achieving a low distortion rate and stable quality, a 2-piece system with a special cloth on the edge is adopted, and the piston vibration range is expanded by the soft edge.
A dome-type super tweeter with a small diameter up to 1.4 cm and wide dispersion is mounted in the super high frequency range.
Titanium, which is as rigid as the tweeter, is used for the diaphragm to improve high frequency transient and efficiency.
The enclosure has a rosewood-like finish.
In addition, the Super Tweeter and Tweeter are combined into an integrated frame, and the Woofer is arranged vertically on the center axis of the cabinet to improve orientation and sound field feeling.
