The Bogen SPT15A and SP158A are compact, high intelligibility, reentrant type
loudspeakers, designed for one-way or two-way* sound and communication systems.
Their sturdy, weatherproof, all metal construction is ideal for indoor and outdoor
use in industrial plants, warehouses, schools, construction sites, transportation
terminals, and recreational areas. Screw terminals make installation fast and
easy. The Model SPT15A has a built-in, variable impedance selector switch for
matching the speaker power requirements to a 25V or 70V constant-voltage line.
The model SP158A has an 8-ohm impedance. Engineered to simplify installation (with
a uniquely designed all-purpose mounting bracket) and field maintenance (with
a self-aligning, field replaceable diaphragm), use of Bogen horn-type loudspeakers
saves both time and money. The speaker and mounting bracket are handsomely finished
in textured mocha enamel. It has a 9" diameter and is 9-1/4" deep.

equipment.- High intelligibility and efficiency; ideal for both one-way
and talk back applications
