Snell Performance From an In-Ceiling Speaker
The Snell OH-R7 speaker provides the exceptional Snell sound from an in-ceiling speaker. In addition the OH-R7 incor-
porates an angled, rotatable midrange/tweeter baffl e that enables it to deliver ideal imaging characteristics in virtually
any installation situation. This is particularly important in home theater installations. In these installations front
channel speaker need to project sound directly toward the listener, but surround speakers need to direct their sound
away from the listener to produce a diffuse sound. The woofer is positioned at an angle behind the midrange/tweeter,
delivering its sound through a crescent-shaped opening.
The OH-R7 features a boundary compensation switch that allows the sound of each speaker to be adjusted to produce
the best sound possible wherever it is installed.
Rugged paintable aluminum grilles and easy-to-use mounting hardware make the OH-R7 easy to integrate, visually
and mechanically into any installation.

Warning
– Always turn off the amplifi er or receiver when connecting speakers or any other components to the system.
Note
– Installation should only be performed by professional installers or those possessing skills in construction, expe-
rience with the proper use of hand and power tools, knowledge of local building and electrical codes, and familiarity
with the environment in which the OH-R7 will be installed. Install the speakers to meet all local building, energy, and
electrical codes.
P L A C E M E N T
Since the speaker installation is permanent and the furniture placement may not be, you should fi rst determine the
best long-term location for the speakers — one that will accommodate relocation of the furniture in the room while
still providing well-balanced sound to the primary listening area.
The tweeter and midrange baffl e of the speaker is angled to deliver accurate
on-axis response to the listening area. The baffl e must be properly posi-
tioned to deliver the best sound. The illustration shows how the sound is
directed relative to the position of the midrange/tweeter baffl e position.
