The Bogen Models S86 and S8
1
0 8" cone-type loud-
speakers provide excellent sound quality and trouble-
free operation. Their magnetic structure is designed
for maximum air gap energy and the diaphragms have
been selected for high sensitivity and optimized
response characteristics. The speakers are easy to
install in ceiling grilles or wall baffles. Mounting holes
have been provided for quick attachment of a trans-
former.
Transformers include the Model T725, which matches
an 8-ohm speaker to a 25- or 70-volt line with six
power taps for either voltage (4, 2,

The S86 and S8

versions, with the Model T725 transformer already

(Model WB8), or in ceiling grilles for recessed instal-
lation. Assemblies are also available with optional vol-
ume control and/or terminal strip.
