ABOUT THE H480-2 MOUNTING CLAMP DESIGN
The H480-2 speaker features rigid, heavy-duty
mounting clamps that ensure a quick, secure,
vibration-free installation in walls from 1/2” to 1-1/2” in
thickness.
The H480-2 model has four mounting clamps.
DAMPING THE WALL CAVITY
Damping the wall/ceiling cavity behind the speakers
by loosely filling it with fire-rated fiberglass insulation
can enhance the performance of your speakers and
reduce unwanted transmission of sound into adjacent
rooms.
PAINTING THE SPEAKERS
All speakers can be finished to match any room décor.
Their white, textured frames and no-rust aluminum
grilles readily accept most water-based interior latex
and spray enamels.
We recommend the grille and frame be painted
separately. To aid in frame painting, we’ve included a
plastic paint shield that will protect the speaker baffle.
Painting Tips:
1. If not using spray paint, we recommend that the
paint be thinned to prevent clogging the speaker
grille perforations.
2. When painting, several light coats will yield the
best results.
As the installation of flush-mount speakers requires
cutting into walls where high-voltage wiring, pipes
and duct work may be present, installation should be
performed by experienced and trained professionals
only.
NOTES:
•
Check for Obstructions
––Before cutting holes
in any existing wall or ceiling surface, the cavity
behind each speaker’s installation location MUST
be probed for obstructions. Make sure to probe
both speaker locations in the room to ensure that
symmetrical placement is feasible.
•
New Construction Installation—
In new
construction installations, the H481-6 mounting
brackets can be used to mount the H480-2
speakers. The H481-6 brackets can be
mounted before the drywall is installed. Visit
the openhousesystem.com web site for further
information.
• Always maintain proper polarity when wiring
speakers. Failure to do so will result in poor stereo
imaging and a decrease in base response.
CUTTING SPEAKER OPENINGS IN FINISHED WALLS
1. Use a stud finder to locate the studs around the
intended speaker placement.
NOTE:
A stud-
finding device MAY NOT detect pipes, wiring, or
other obstructions located behind the drywall.
2. Use the inside portion of the speaker cutout
template to confirm the speaker placements.
3. Remove templates and drill or carefully poke a
pilot hole in both locations. A bent piece of wire
or a coat hanger may be used to probe the stud bay
for obstructions. If you experience resistance of
any kind––
STOP!
If any obstructions are detected,
patch the pilot holes and try again in another
location.
4. Once you have determined the cavity is free from
obstructions, re-position the cutout template and
use a pencil to lightly trace the perimeter of the
tem-plate.
5. Use a keyhole saw, drywall router, or razor knife to
cut the openings.
IN-CEILING SPEAKER INSTALLATION:
Complete Assemblies
(with or without New
Construction Brackets)
1. Remove speaker grille
2. Locate the speaker wire and pull through the
ceiling opening.
IMPORTANT NOTE:
The slim design
of the H480-2 speaker frame flanges
require that careful attention be paid
to not oversize the cut-out hole.
