foot ceilings and above) apart but no closer than
2 feet to any adjacent wall. Avoid placing
speakers in air return cavities. Some type of
protection will be required for the back of the
speaker if blown insulation is used. The following
is a partial list of ways to protect the speaker:
• Use an RE-16 speaker cover
• Use a piece of wood that will cover at least 3
feet on either side of the speaker opening.
The ends may be partially closed to keep the
blown insulation from reaching the speaker,
however, a minimum gap of 2 inches at each
end is better than a sealed box
• Use a piece of bat insulation at least 3 inches
thick over the back of the speaker. This
insulation should not have a backing or if it
does, the backing must be installed facing
away from the speaker.
• Use a fine mesh to cover the back of the
speaker to protect against bulk type insulation
materials. This will not work with insulation
containing fine powders.
Do not install speakers in joist cavities containing
120/240V appliances, within 18 inches of dimmer
light fixtures, security wiring and other control
wiring.
In-wall Installation
Careful consideration must be given to the
speaker location to realize the full frequency
range. In-wall speakers should be spaced 6 to 8
feet apart but no closer than 2 feet to any
adjacent wall or ceiling. Typical height from the
floor would be in the 4 to 6 foot range. Avoid
placing speakers in air return wall cavities,
outside walls or walls containing plumbing.
