Multi-High Power Series 4-way speaker system, an improved version of the High Power Series.

A 30 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.

It is equipped with a 16 cm cone type squaker for the middle and low range and a 13 cm cone type squaker for the middle and high range.
These units use a dome radiator made of 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.

A 9 cm cone type tweeter is installed in the high range.
Large input and high efficiency are achieved by a lightweight large diameter voice coil using a strong magnetic circuit and aluminum wire.

A horn type tweeter is installed in the ultra-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 (middle low band, middle high band) and high band (high band and ultra high band). Multi-amplifier driving is possible by preparing a channel divider and amplifier.
The all-band input is also equipped with a jack that can be easily connected with a plug.
