Using As a Surround Speaker
The compact size and neutral tonal quality of the OH-S7 and OH-T7 make them perfect for the
surround channel speakers of a home theater system. Place the speakers toward the back of the
room, to the sides of, or behind the listening
position.
An indirect sound path from the speakers to
the listening position results in a more diffuse
and convincing surround sound effect. This
can be achieved by taking advantage of the
angled waveguide tweeter. Orient (rotate)
the speakers so that the tweeters point away
from the listening area. Mounting speakers
fairly far back, and fairly high, on the side
walls, with the tweeter aimed toward the rear
wall of the listening area, will give excellent
results.
PAINTING THE SPEAKERS
If you intend to paint the speakers, it’s best to do so before you install them. Typically, a primer
coat is not necessary.
1. Remove the speaker grille. Carefully pry on one edge with an awl or small screwdriver. If
you choose to paint the metal grille, do so after detaching it from the speaker.
Note:
You may fi nd it helpful to thin the paint to be used on
the grille. This prevents the paint from fi lling the holes.
2. Use the form-fi tting painting mask provided to paint
the housing. Shape it into a cone and insert the two
tabs into their adjacent slots.
3. After the paint has dried, remove the mask by care-
fully inserting a screwdriver into the slots and prying
upward.
PREPARING FOR INSTALLATION
Take the following steps to prepare for installation:
/
Map out the wiring paths from the speakers to the amplifi er. We recommend 16-gauge
cable or thicker for runs up to 25 feet (8m) and 12-gauge wire or thicker for longer runs.
/
Be sure the speaker wire does not rest or rub against any sharp or pointed objects.
/
Each speaker is 8 ohms nominal. When connecting more than two speakers per amplifi er
channel, you should use series wiring or an impedance protection device, such as a line
transformer.
/
Make sure that the total system’s impedance does not fall below the amplifi er’s minimum
rating. If you are not certain, consult your Snell Acoustics dealer.
