This is a bookshelf type speaker system designed by Paul Supran Gar who was the top engineer of Altec.

A 25 cm cone type woofer is installed in the low range.

A horn type tweeter combining a semiconductor tweeter LZT originally developed by Altec and a Mantare horn is mounted in the high frequency range.
The vibration plate of this tweeter is a semiconductor type, and by combining Altec's original Tangerine phase plug and Mantare horn, flat high-frequency characteristics and uniform directional characteristics are realized.

Automatic power control and overload indicator are used to protect the speakers.

A level control is provided for the high-frequency band.

The enclosure uses a bass reflex system.
anechoic dump front baffle is used for the front baffle, and natural wood finish is applied to the other surface.
