ALTEC LANSING 620B Monitor/718A Monitor

Commentary

A speaker system that uses 604 to 8 h.

38 cm coaxial 2-way speaker 604-8H is mounted as a unit.
A horn type tweeter using a manta ray Lehorn is mounted in the high range of 604 to 8 h, and the uniform diffusion of high range energy is realized by adopting a Tangerine phase plug.

The network section contains an equalizer correction circuit.
This circuit can be switched between a normal 2-way state and a state in which the audibility compensation circuit is turned on by switching the switch, and the high-end of 10 kHz or higher can be adjusted to the listening position.

The enclosure has a bass reflex design that was designed by analyzing various characteristics from 604 to 8 Hz.

The 620B Monitor has a walnut full-surface finish with a upholstery thin RUNNET, and the 718A Monitor has a front black baffle finish with a translucent thin RUNNET.
