Damping the Wall Cavity

H480-2 INSTALLATION INSTRUCTIONS

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/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.

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.
