ABOUT THE H480-2 MOUNTING CLAMP DESIGN  
mounted before the drywall is installed. Visit  
the openhousesystem.com web site for further  
information.  
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.  
• Always maintain proper polarity when wiring  
speakers. Failure to do so will result in poor stereo  
imaging and a decrease in base response.  
The H480-2 model has four mounting clamps.  
DAMPINGTHEWALL CAVITY  
CUTTING SPEAKER OPENINGS IN FINISHEDWALLS  
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.  
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.  
PAINTING THE SPEAKERS  
2. Use the inside portion of the speaker cutout  
template to confirm the speaker placements.  
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.  
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.  
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.  
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.  
2. When painting, several light coats will yield the  
best results.  
5. Use a keyhole saw, drywall router, or razor knife to  
cut the openings.  
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.  
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.  
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.
