Horn Loudspeakers

SPT5A and SP58A
The SPT5A and SP58A are compact, reflex-type horn loudspeakers, designed for one-way or two-way sound and communications systems. Their wide frequency response assures full-range background music reproduction, making these loudspeakers an excellent choice for multi-purpose applications, indoor or outdoor, for use in industrial plants, warehouses, schools, construction sites, transportation terminals, and recreational areas. The SPT5A has a built-in, variable impedance selector switch for matching the speaker power requirements to a 25V or 70V constant-voltage line. The SP58A has an 8-ohm impedance. The loudspeakers measure 6" in diameter and 4" deep. Connections are made through a 12" connecting cable.

SPT15A and SP158A 
The SPT15A and SP158A are compact, high intelligibility, reentrant-type horn 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. The Model SPT15A has a built-in, rotary 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 only.

SPT30A and SP308A
The SPT30A and SP308A are compact, high intelligibility, reentrant-type horn 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. 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 only.
