ID60D-8
ID60DT
Heavy-Duty
Compression Drivers
General Product Description
The ID60D-8 and ID60DT are heavy-duty compression
drivers for use in high-power public address installations.
The drivers employ rugged phenolic diaphragms, 2-inch
diameter voice coils and “rim centered” ferrite magnet
structures for long life and reliability under extreme operating
conditions.
A hinged cycolac rear housing for easy access and
connection to a sound system, via a BX conduit connector,
is provided together with a plug-in, field replaceable
diaphragm assembly.
The transformer model (ID60DT) includes connections for
25-V and 70-V distributed systems and a screwdriver
operated power-tap select switch.
The exterior is finished in durable, weatherproof paint, and
all metal parts have been tropicalized for resistance to high
humidity and fungus.
Ideal for both indoor and outdoor applications, these drivers
are well suited for any installation requiring rugged,
high-power performance.
