This 6-way bookshelf speaker system is the top model of the High Power Series.

A 38 cm cone type woofer is installed in the low range.
By combining a powerful magnetic circuit using a large magnet, a large diameter voice coil of 100 φ, Coral's unique long travel voice coil and skybar edge, it realizes Dainyu force, high efficiency, low distortion, and low fo.

Equipped with a 16 cm cone scoker for the middle and low range, a 12 cm cone scoker for the middle range, and a horn scoker for the middle and high range.
The cone squaker uses a dome radiator made by Super Duralumin to improve the connection to the high range. In addition, the 12 cm cone squaker uses a completely sealed structure in the frame to eliminate the influence of the back pressure of the woofer.
The Horn Squaker is used for the BX-700 and BX-710 and uses a film diaphragm.

A 9 cm cone type tweeter is installed in the high range.
The cone tweeter uses a voice coil with a strong magnetic circuit and aluminum wire to enable large input and high efficiency.

Two horn type super tweeters are installed in the super high range.
A film diaphragm is used for the diaphragm and the weight reduction of the vibration system enables high-frequency reproduction at 25 kHz.

A constant impedance type level control is provided for the middle and high frequencies.

The enclosure uses a bass reflex method and has a walnut polyurethane finish on the exterior.
The front grill uses a reversible grill a reversible grill of Sa RUNNET which is arranged with a handmade grating and aluminum sash, and there are 3 combinations including metal baffle.

The rear terminal is equipped with a jack that can be connected with a plug in addition to the conventional terminal.

The switch on the rear panel allows three independent multi-amp drives : low, mid-range (mid-low to mid-high range), and high range (high to ultra high range).
In multi-amplifier mode, the network and attenuator are disconnected, so a channel divider and amplifier for each band are required.
