TOOLS AND PRECAUTIONS
We recommend using the following tools to install an HDFX 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 150 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 22 for more information about
amplifier clipping distortion.
