Pre-construction brackets are position-able and designed to span up
to 24" centers. The mounting hole cut-out can be placed at any point
between studs, joists or trusses.
If you use pre-construction brackets, the installation of your speakers
will be easier and much faster because the drywall installers will do
the cutting for you.
There are several Pre-construction bracket models:
•
RIR-5, 6, & 8 for the round speakers
(figure 6)
•
RIB-5, 7 & 8 for the rectangular speakers
(figure 7)
2.
Fasten the pre-construction brackets in their respective locations.
After fastening the mounting straps to the studs or trusses, slide the
mounting hole cut-out portion of the bracket into the desired
position.
3.
Choose a location in the wall close to the stereo equipment center
(ideally within 6') to mount a multi-gang “J-box”
(figures 1a & 5)
for the head-out. Preferably, this location will be easily accessible
and will not be visible once the equipment is in place.
4.
What Size “J-boxes”?
Each “gang” when IWM-8BPG jack plates are used
(figure 4a)
will
accommodate two pairs of speakers. So a 3 gang J-box will provide
termination for six rooms or six pairs of speakers at the head-out
point
(figure 4b)
.
Following the example of six rooms, obtain:
•
One 3 gang J-box for the head-out termination
new construction
nail-on type
(figure 1a)
•
Six 22.5 cubic inch 3 5/8" deep single gang J-boxes for the
volume controls
new construction nail-on type
(figure 2a)
5.
Fasten the head-out J-box.
6.
Fasten the volume control J-boxes in their respective locations,
usually at light switch height.
Now you are ready to run the wire.
