A speaker system developed by Ferrograph Ltd. of the United Kingdom, which has announced many products as a specialized manufacturer of tape recorders.
An elliptical plastic cone woofer unit is mounted in the low range.
The middle area is equipped with a 12 cm cone type squaker with a plastic edge and an effective diameter of approximately 10 cm.
A dome type tweeter is installed in the high range.
The three speaker units are incorporated into a ducted-port enclosure, which consists of a baffle board with cutouts in the corners and partitions to form a long duct, and are wrapped in sound absorbing material inside the enclosure.
The enclosure is constructed from a rigid chipboard, to which stands with casters are attached for optimum listening position.
