Installation Cautions
Installation of Disappearing Series Loudspeakers requires skills in using
tools such as a drill, screwdriver, saws and power tools. Installation also
entails running wires through walls. You should have a thorough under-
standing of local building and fire codes and a familiarity with the area
behind the wall or ceiling into which you plan to install your speakers.
When cutting holes in and running wires through walls/ceilings, you
run the risk of cutting electrical wires or water pipes, thereby causing
safety hazards and property damage. If you are in any doubt that you
possess the necessary skills or tools, contact your Definitive Technology
dealer, general contractor or a professional installer.
Required Tools
• Pencil for marking the location of installation.
• Bubble level
• Keyhole saw, utility knife or material- appropriate incising implement
for cutting drywall or other wall material.
• Phillips head screwdriver.
• Power drill with appropriate bit (optional, for starting wall cut).
Installation Procedure
You must first install speaker wires that meet appropriate building and fire
codes before installing the speakers. Use at least 18 gauge wire or heavier to
ensure optimum sound quality.
• Make sure the material into which you plan to mount the speakers
(plaster, drywall, paneling, stone, etc.) can support the weight of the
speakers (see specification page for the weight of your model).
• Make sure the locations you select do not conceal studs, electrical wiring
or plumbing. Prior to installation, hold the speaker with grille on in your
chosen location to make sure it safely clears obstacles such as studs,
corners, beams, lighting fixtures and door/window frames. Your cutout
must be at least 2" (50 mm) from adjoining walls or ceiling, internal studs
or plumbing.
• NOTE: The DI 5.5
LCR will fit between studs when used horizontally but
only if it is perfectly centered between the studs. Plan the placement of
your on-wall TV and speakers very carefully before cutting holes. The DI
6.5LCR will not fit between standard-spaced wall studs when used in a
horizontal orientation. If you wish to use a DI 6.5LCR as a horizontal center
channel speaker or if you cannot center a DI 5.5LCR between studs, consult
a professional installer.
• Using the supplied template, trace the installation location with a
pencil. You can do this by holding the template in your preferred
location and tracing around it. Use a bubble level to square and level
the template [Figure 4].
• Carefully cut the hole with the appropriate cutting tool for your wall
or ceiling material. Start the hole by drilling a hole on the inside of the
tracing (with the drill bit just inside the line). Use this hole to insert the
saw or knife and begin cutting [Figure 5].
• Once you have cut the hole, pull the speaker wire out of the hole and
connect the speaker. Strip 1/2" inch (12 mm) of insulation from each of
the two conductors of the wire to expose the bare metal and twist each
of the conductors into a single unfrayed strand. Note that one of the
terminals on the rear of each speaker is marked red (+) and the other
black (-). Make certain that you connect the wire from the red terminal
(+) of your amplifier or receiver to the red terminal (+) on your speaker
and the wire from the black terminal (-) of your amplifier or receiver to
the black terminal (-) on your speaker. Most wire has some indicator
(such as color-coding, ribbing or writing) on one of the two conductors
to help you maintain consistency [Figure 6].
