TOOLS AND PRECAUTIONS
We recommend using the following tools to install a CM6HDfx loudspeaker:
• Electric drill with 1/4- and 1/2-inch drill bits, and a 1-inch flat drill bit
(for drilling through studs)
• Keyhole or drywall saw
• Stiff wire, fish tape, or glow rods (for routing cables)
• Phillips screwdriver set
• Cable ties
• Pencil
• Level
• Rubber gloves and protective eyewear
Before starting the installation, please observe the following precautions:
• Turn off all system power before making any connections.
• Always wear protective eyewear when using tools.
• Make sure hands are clean before installation.
• Wear gloves when working with fiberglass insulation.
RECOMMENDED AMPLIFIER POWER
For satisfactory performance, we recommend using a surround amplifier with a power rating of
10 to 125 watts. Curiously, most loudspeakers are not damaged by large amplifiers, but rather by
small amplifiers. If your system is playing loud music, a small amplifier will run out of power very
quickly and can create damaging “clipping” distortions. A more powerful amplifier will play at the
same volume without distorting. See
OPERATION
on page 19 for more information about amplifier
clipping distortion.
