7.5 Watt, 25V or 70V Reflex Horn Loudspeaker
The Bogen SPT5A is a compact, reflex horn-type loudspeaker,
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 loudspeakers measure 6" in diameter and 4" deep.
Connections are made through a 12" connecting cable. |
