Features
Loudspeakers
• High intelligibility and efficiency; ideal for both one-way and talk back applications
• Weatherproof, all metal construction
• 15 watts; 25/70 volt or 8-ohm operation
• Variable-tap impedance selector on SPT15A
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 con-
struction 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.
* These are not talk back horns.Their use in two-way applications requires additional equipment.
Models SPT15A
and SP158A
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" diam-
eter and is 9-1/4" deep.
Specifications subject to change without notice.
