Like our other Blueprint Series
Loudspeakers, these ceiling mount mod-
els offer Niles durability and installation
ease and are designed for unobtrusive
installations.
Model 75 measures a compact 7 by 7
inches square; Model 76 is a similarly
compact round design measuring 7-3/4
inches in diameter. Both feature a weath-
er-resistant 5-1/4 inch polypropylene co-
axial driver system with a butyl rubber
surround and powder coated aluminum
grills, making them suitable for bathroom
and outdoor patio applications. Both
models employ a bracketless mounting
system: simply cut a hole in the mount-
ing surface and tighten the four clamps
via front-baffle screws. And like other
Blueprint Series speakers, the flush, tight-
mesh grills can be painted or covered to
blend with the surrounding decor.
Model 77 is similar to Model 76 but is
designed to masquerade as a recessed
lighting fixture. Its recessed black grill is
attached to a 6-1/4 inch diameter black
collar which fits neatly into the bezel.
Model 77 blends in quietly with neigh-
boring light fixtures while providing a
“floodlight” of sound.
FEATURES & BENEFITS
INSTALLATION AND OPERATION GUIDE
Thank you for choosing a Blueprint
Series
®
Loudspeaker from Niles. With
proper installation and operation, you’ll
enjoy years of trouble-free use.
CONTINUED OTHER SIDE
The Models 75, 76 and 77 are designed
to work well in any standard ceiling or
wall. For the Model 75, the mounting
surface must be between 3/8 and 5/8
inch thick. All models will perform well
in any air volume greater than .5 cubic
feet.
When wall mounting the speakers, the
best stereo effect will be achieved if both
the speakers are at equal distance from
the listener and closer together than the
listener is from the speakers. Avoid
installing the speakers near corners to
prevent a “boomy” or diffracted sound.
These speakers, like all Blueprint Series
Loudspeakers, are designed to be mini-
mally affected by long lengths of speaker
wire. The Models 75, 76 and 77 will
accommodate speaker wire between 12
and 22 gauge.
