CORAL BX-multi1500

Commentary

This 6-way speaker system is the top-of-the-line model of the Multi High Power Series, an improved version of the High Power Series.

A 38 cm cone type woofer is installed in the low range.
It uses a magnetic circuit with a large magnet and a voice coil with a large diameter of 100 φ. It is combined with Coral's unique long travel voice coil and skybar edge to achieve large input, high efficiency, and low fo.

A 16 cm cone type squaker is installed in the middle and low range, and a 13 cm cone type squaker is installed in the middle 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 horn type skoker is installed in the middle and high area.
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.
Large input and high efficiency are achieved by a lightweight large diameter voice coil using a strong magnetic circuit and aluminum wire.

Two horn type 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.

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

The enclosure uses a bass reflex system.
The exterior features a walnut polyurethane finish, and the front grill features a RUNNET reversible grill with a handmade grating and aluminum sash.

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.
