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.
