Features
Loudspeakers
Models SPT30A
* These are not talk-back horns. Their use in two-way applications requires
additional equipment.
• High intelligibility and efficiency; ideal for both one-way and talkback applications
• Weatherproof, all metal construction
• 30 watts; 25/70 volt or 8-ohm operation
• Variable-tap impedance selector on SPT30A
• Beam clamp available (BC1)
The Bogen SPT30A and SP308A are compact, high
intelligibility, reentrant type loudspeakers, designed for
one-way or two-way* sound and communication sys-
tems. Their sturdy, weatherproof, all metal construc-
tion is ideal for indoor and outdoor use in industrial
plants, warehouses, schools, construction sites, trans-
portation terminals, and recreational areas. Screw ter-
minals make installation fast and easy.
The Model SPT30A has a built-in, variable impedance
selector switch for matching the speaker power
requirements to a 25V or 70V constant-voltage line.
The model SP308A has an 8-ohm impedance.
and SP308A
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.
Speaker and mounting bracket are handsomely fin-
ished in textured mocha enamel. Diameter is 11" with
a depth of 10-1/2". A beam clamp is also available
(BC1), as an option.
Specifications subject to change without notice.
