2. If an On-Q Speaker Pre-Construction Bracket is to be used, skip to
Step “5 ” and refer to IS-0243 for detailed instructions.
3. If
pre-wiring without using the On-Q Pre-Construction Speaker
Brackets, leave 4 to 6 feet of wire at the speakers intended location.
Use a strip of cardboard stapled to the joints/studs with a hole
through it as a wire place holder for the drywall installers if
installation of the speakers is intended (see Figure 3).
4. After drywall and/or painting is complete, push wire through hole,
center template over hole, mark with a pencil and cut out with a dry-
wall knife.
5. When using the On-Q Pre-Construction Bracket (see
Figure 4 ), leave a coil of speaker wire on top of the
bracket coiled around the speaker mounting hole. There
are clips on the corner of the bracket to secure the
speaker wire. Leave enough speaker wire to be able to
pull the wire through the bracket and comfortably
connect the wire to the speaker after the drywall is
installed. Strip off 3 inches or so of the speaker cable
jacket to expose the positive and negative insulated
wires. Strip 3/8-1/2 inch of insulation off of these
conductors.
6. It is recommended to place insulation behind the
speaker to provide some damping for the woofer driver.
This will yield the best possible sound. On-Q
recommends using poly-encapsulated insulation such as
Johns Manville Comfort Therm®. If a defined, consistent
sound is desired from both speakers in a space, blocking
can be installed to yield the ideal cubic footage for each
driver. Insulation would then be put in this space during
speaker installation. Refer to blocking chart for
details.
7. If installing speakers in a space with an attic above it is
recommended that the speakers be boxed in with 1/2 inch
MDF (medium density fiber board) or plywood with
insulation installed. This will provide a defined acoustic
space and protect the speaker. The best possible sound
will be achieved by doing this. Refer to the blocking
chart for details.
Note: Make sure you are in compliance with local building codes before installing this speaker in
an attic space.
