Multi-High Power Series 3-way speaker system, an improved version of High Power Series.

A 25 cm cone type woofer is installed in the low range.
It employs a powerful magnetic circuit using a large magnet equivalent to the 30 cm class of conventional Coral products and a large diameter voice coil. Combined with the use of Coral's unique long travel voice coil and skybar edge, it achieves a large input, high efficiency, low distortion and low fo.

A 16 cm cone type squaker is mounted in the middle area.
This unit uses a dome radiator made by Super Duralumin to improve the connection from the mid-range to the high-range, and a newly developed damper provides appropriate braking to achieve a flatter frequency response.
The frame has a completely sealed structure to eliminate the adverse effect of the back pressure of the woofer.

Two horn type tweeters are installed in the 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.

Equipped with level control, you can adjust the middle and high ranges independently.

The enclosure uses a bass reflex system.
The exterior has a walnut polyurethane finish, and the front grill uses a grating grill.

In addition to the normal input terminal, an independent input terminal is mounted for each band of low band, middle band and high band. Multi-amplifier driving is possible by preparing channel dividers and amplifiers.
The all-band input is also equipped with a jack that can be easily connected with a plug.
