The Bogen Models S86 and S810 8" cone-type loud-
speak ers pr ovide excellent sound quality and tr ouble-
free operation. Their magnetic structure is designed
for maximum air ga p 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.
Transf ormers include the Model T725,which matches
an 8-ohm speaker to a 25- or 70-volt line with six
pow er taps f or either voltage (4,2,1,1/2,1/4,and 1/8
watt), and the Model T72510 which matches an 8-
ohm speaker to a 25- or 70-volt line with five power
taps for either voltage (10,5,2-1/2, 1-1/4,5/8 watts).
The S86 and S810 are available in factory assembled
versions, with the Model T725 transformer already
mounted. The S86 assembly is also available with a
terminal strip (-BR),and volume control (-V).
Bogen also offers the speakers,fully assembled with a
transformer, in an attractively finished wall baffle
(Model WB8), or in ceiling grilles for recessed instal-
lation. Assemblies are also available with optional v ol-
ume control and/or terminal strip.

Wall Baffle , Grilles, Accessories
• Sturdily constructed
• Attractively styled and finished
• Wall baffle surface mounts at an angle for downward sound dispersion
WB8 Wall Baffle
The WB8 baffle is ruggedly constructed of 3/8" particle board,glued and covered in
simulated walnut vin yl with a black grille cloth. Side corner joints are r einfor ced with
glue blocks. It is handsomely styled and looks well in vir tually any decor. The slop-
ing front provides extra downward sound dispersion.
Ceiling Grilles
Sturdily constructed and handsomely styled, these metal grilles protect and conceal
recessed 8" ceiling speakers. They are shipped complete with the hardware needed
to mount speaker to grille . Models CG8A,CG8AW, PG8A, PG8W, and SG8W.
RE84 Ceiling Speaker Enclosure
The RE84 is a protective enclosure for an 8" speaker, designed for recessed instal-
lations, and for use with any of the Bogen ceiling grilles. One-piece steel construc-
tion includes a mounting ring and a foam insert to reduce metallic resonance . The
RE84 is finished in rust-resistant black primer and is tapered for easy stacking.
UL approved.
MR8 Mounting Ring
The MR8 is a cold-r olled steel unit which will mount any of the Bogen ceiling grilles,
for installations where the RE84 is not used.
TB8 Tile Bridge
The TB8 is a load bearing T-bar support designed to sustain the weight of an 8"
speak er,grille and protective enclosur e in suspended ceiling construction. Use of the
TB8 improves environmental safety and eliminates unsightly sag in 2'-by-2' and 20'-
by-4' acoustic ceiling tiles.
Speaker Line Attenuators
The AT10A and AT35A are 10-watt and 35-watt attenuators that permit setting
the output level at loudspeakers on a 25V or 70V line without altering the amplifier
volume setting. They provide a choice of 10 stops and an "off" position.
