IMPORTANT! IF INSTALLING SUBWOOFER INTO A PARADIGM
®
BACKBOX
Instructions for installing your subwoofer into a backbox were provided with the backbox.
If you no longer have the instructions, follow the instructions on the preceding page.
STIFFENING AND STRENGTHENING THE CAVITY
Although Paradigm in-wall and in-ceiling mounting systems are the most rigid on the market, when
installing your subwoofer directly into a wall or ceiling, to help avoid bass vibrations and minimize
acoustic bleed-through, we recommend the following:
Additional Bracing
Additional cross-bracing will further stiffen the cavity. We suggest placing two to three pieces of 2˝ x 4˝
(more if application allows) within the cavity, evenly spaced above and below the cutout. Additional
bracing can also be sandwiched to the studs/joists on either side of the subwoofer.
New Construction
New construction offers an excellent opportunity to strengthen and stiffen the cavity with additional
bracing or construction-grade stiffening adhesives applied directly to the drywall.
(See Dealer for
more information.)
1. Mounting
Keeping in mind the recommendations above, place mounting template onto wall or ceiling. Cut hole as
indicated in Figs. 4a and 5a.
Damping Material and Other Acoustic Treatments
To ensure optimal results, do not compact damping material
during the damping process described below.
Additional soundproofing treatments
(i.e. Dynamat
®
, see Dealer for more information)
can be used against
the back wall of the cavity or above and below the cutout on the inside front of the wall or ceiling.
In-Wall Mounting:
For optimum performance, loosely place a minimum of …
• Two pieces, 8˝ (20 cm) to 12˝ (30 cm) long, of standard fiberglass insulation in the wall. R-12 for 2˝ x
4˝ (5 cm x 10 cm) walls or R-20 for 2˝ x 6˝ (5 cm x 15 cm) walls. Place one piece just above and just below
the mounting hole;
• A half-thick piece of fiberglass insulation, the same height as the subwoofer, in the wall directly behind
the mounting hole, allowing enough space for the subwoofer to properly recess into the cavity.
In-Ceiling Mounting:
For optimum performance, loosely place a minimum of …
• One piece of standard fiberglass (to fit joist size) above the subwoofer extending 12˝ (30 cm) or more
beyond the speaker between the joists, allowing enough space for the subwoofer to properly recess
into the cavity;
• (For taller joists) install fiberglass insulation directly against the joists on either side of the mounting hole.
