Commentary
Floor-type speaker system using FB cone.
A 30 cm cone type woofer is installed in the low range.
In addition, a 16 cm cone-type midbus and a 10 cm cone-type midhigh are installed in the mid-range. By dividing the mid-range, which is important for sound quality, it improves playback sound and eliminates IM distortion.
A multi-seller horn type tweeter is installed in the high range.
The level control is mounted on the front baffle to improve the operability.
In addition to the normal full-range input, terminals for 2-way and 3-way multi-amplifier are mounted on the rear terminal.
The enclosure uses a bass reflex system.
In addition, both sides of the front baffle are eliminated and holes are made in the side of the grill frame to improve directional characteristics.
