CINEMA TWO SUB, NEW CONSTRUCTION–BACK BOX INSTALLATION
Insert the Cinema Two SUB Back Box between studs, moving the studs if necessary to achieve proper
fit.Attach the back box with the L brackets provided, or if back box is installed against the floor plate,
use long 2-1/2" screws through the studs into the sides of the back box every 12". For optimum
performance, mount back boxes as low and near to a corner as possible.
Drill a hole as small as possible in the rear or side panel of the back box and pass the speaker wire
through it. For ease of speaker installation, leave two feet of extra wire beyond the actual speaker
mounting location. Seal the hole with silicone caulking compound.
CINEMA TWO SUB, RETROFIT–BACK BOX INSTALLATION
Survey proposed sites and look for installation obstacles, e.g., plumbing, wiring and other fixtures.
Access the attic or crawl space to check routing of air ducts and available mounting depth: Cinema Two
SUBs require a wall cavity 5-3/4" deep and 84" tall.
At each selected site, use a stud locator to identify an open space between studs. Drill a small hole in
the center of the chosen area and insert a bent coat hanger to confirm that the cavity is clear.
Use a stud finder to locate the studs that define the cavity. Using a drywall saw, make two horizontal
cuts along the inside of the studs, creating an opening at least 84" high. The bottom cut should be 6"
below the desired bottom of the back box (to accommodate L brackets). The upper cut should be 6 "
above the desired top of the back box. Next, make two vertical cuts along the inside edges of the studs,
connecting the horizontal cuts. Remove the drywall and set aside.
Insert the Cinema Back Box and attach the top and bottom to the studs with the L brackets provided.
Fill any gap between the back box and side studs with scrap wood or drywall to assure a snug fit. Drill
a hole as small as possible in the back box and pass the speaker wire through it. Seal the hole with
silicone caulking compound.Leave two feet of extra wire beyond the actual speaker mounting location
for ease of speaker installation.
Use the wood plate protruding from back box as a template to cut drywall. Apply silicone caulking
compound or construction adhesive to the back side of the removed drywall. Replace the drywall and
attach it to the back box with 1" drywall screws every 3-4" around the perimeter of the box.

INSTALLATION SAFETY
When installing Sonance Cinema speakers, basic
safety precautions should always be followed to
reduce the risk of fire,electric shock,and injury to
persons, including the following:
1. Read and understand all instructions.
2. Never drill or cut into wall cavities that already
contain electrical wiring or plumbing.
3. Follow all warnings and instructions in this
manual and marked on the product.
4. Do not install this product in a high humidity
environment or near water, for example a wet
basement, wet bar,or swimming pool.
5. Never touch the drivers or push objects of any
kind into this product through the grilles.
6. Always exercise caution when working in
unfinished spaces such as attics. Areas with
exposed joists present a significant danger of
injury from falls or stepping on nonstructural
surfaces.Before working in areas with exposed
joists,always create temporary walkways using
plywood or dimensional lumber strong
enough to support your weight.
CARE AND MAINTENANCE
1. Retain the safety and operating instructions for
future reference.
2. Any service or repair required must be performed
by qualified, factory authorized personnel.
3. Do not use liquid or aerosol cleaners on the speakers.
4. To clean your speakers, wipe the grilles with a soft
cloth dampened with water. You may remove the
grilles to wash and dry them. The baffle, drivers,
and CAAD may be dusted by gentle use of
“canned air” commonly used to clean cameras and
computer equipment.
5. Do not use this product in a high humidity
environment or near water, for example a wet
basement, wet bar,or swimming pool.
6. Do not expose your Cinema speakers to direct
sunlight or high heat.Extended periods of exposure
may cause deterioration of adhesives and driver
materials, compromising the useful life of
the speakers.
7. Sine wave test tones can damage your Cinema
speakers and should only be used at low volume
levels for short periods.
8. Never touch the drivers or push objects of any kind
into this product through the grilles.
9. Do not expose your Cinema speakers to construction
dust, dirt, or airborne paint particles. If the area in
which your speakers are installed is subject to
potentially damaging airborne particles, you may
remove the grilles, temporarily cover them with
paper or plastic food wrap, then replace them over
the speakers. Be sure to remove this protective cover
after the dirty activity is complete and the room is
thoroughly cleaned.
