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: • T

LOUDSPEAKER WIRE Use 2-conductor loudspeaker wire when connecting loudspeakers to your receiver or amplifier. For most applications, we recommend using 16- or 18-gauge wire. For wiring runs longer than 80 feet, we recommend 14-gauge wire. The spring-loaded terminals of the HDFX will accommodate up to 12-gauge wire directly. Larger sizes can be accommodated via pin connectors. When running wire inside walls or ceilings, use special jacketed cable (CL-2 or CL-3) to protect the wire and for fire

LOUDSPEAKER PLACEMENT NOTE: THE NILES HDFX LOUDSPEAKER IS DESIGNED FOR USE IN SIDE- OR REAR-CHANNEL APPLICATIONS ONLY. FOR FRONT-OR CENTER-CHANNEL APPLICATIONS, WE RECOMMEND USING A NILES HDLCR OR HDLCRBX LOUDSPEAKER PLACEMENT FOR HOME THEATER REAR APPLICATIONS In home theater, the goal is to reproduce the experience of a great movie theater in your home. The biggest difference between the two venues is the use of a rear- or surround-loudspeaker array in a commercial theater. Here, it is not

THE BOUNDARY EFFECT Placing a loudspeaker in a corner can powerfully affect the way a listener perceives bass response. Known as the boundary effect, placing loudspeakers close to a wall/ceiling boundary or near a corner-wall boundary will emphasize certain bass frequencies, while canceling others. This effect can make the loudspeaker s

RUNNING THE LOUDSPEAKER WIRE IN NEW CONSTRUCTION (CONTINUED) ABOUT DRILLING Use a bit that is large enough for the wires you plan to run. This is an important consideration, since you may be drilling a lot of holes. Here are some additional tips: • We recommend using an auger bit for rough-in wiring. It will actually pull itself through the wood, so that the drill motor, not you, does most of the work. • Alw ays drill the holes in the center of the stud. If you have to notch the stud

CONCEALING LOUDSPEAKER WIRE ABOUT INTERIOR WALLS Interior walls in almost all North American residences are hollow, so they are easy installation sites for flush mounting loudspeakers and routing new loudspeaker cable in the house. Looking at a painted wallboard, plaster, or paneling, you only see the skin of the wall. Behind it is the home’s skeleton; 2-by-4 inch wood or metal “studs” running vertically from the floor to the ceiling in walls and 2-by-6 inch or larger “joists” running horizon

CONCEALING LOUDSPEAKER WIRE (CONTINUED) PLANNING THE LOUDSPEAKER WIRE ROUTE (CONTINUED) To find exactly where an electrical cable is routed, try inspecting the inside of the wall by turn- ing off the breaker for a particular power outlet or switch, removing the cover plate and switch or receptacle, and then shining a penlight into the wall. If you have access to an attic or base- ment space, you can quickly see which part of the wall space is free of obstructions, as shown in Figure 7. Figure 7

OTHER POSSIBLE LOUDSPEAKER WIRE ROUTES INCLUDE: • Under-the-carpet runs using flat loudspeaker wires. • Heating and air conditioning vents used as wire raceways for plenum-rated wire. NOTE: CHECK YOUR LOCAL BUILDING CODES, SINCE SOME MUNICIPALITIES REQUIRE CONDUIT. CUTTING HOLES In traditional wood stud/drywall construction, first cut the hole for the loudspeaker. Then, in the opening, use a drill with a long bit to auger a wire route up or down the wall. Next, cut a hole in the

NEW CONSTRUCTION: INSTALLING A BRACKET The hole-saving bracket enables a faster and cleaner final installation of the loudspeaker. It forces the drywall installer to cut out the loudspeaker hole for you and provides wire ties for the loud- speaker wire, reducing the risks of accidental loss or movement of the wire. In addition, it enables you to align your loudspeakers with other ceiling fixtures with greater accuracy, since you can see exactly where the loudspeaker will be. INSTALLING THE BRAC

CONCEALING LOUDSPEAKER WIRE FOR A FUTURE INSTALLATION 1. Attach the loudspeaker wire in a loop between the wall studs or ceiling joists and carefully mark the exact location of the wire on a set of plans. 2. Ask the general contractor to inform the drywall installers that the loudspeaker wire loops are concealed for future installations, as shown in Figure 12. Figure 12. The loudspeaker wire is looped and hung on two nails attached to the joists, securing it for future use. Be

EXISTING CONSTRUCTION: INSTALLING A BRACKET (CONTINUED) 4. Continue turning the coat hanger as you move it into the cavity to a depth of approxi- mately 4 inches. If you feel an obstruction, fill the hole(s) with spackling compound and repeat steps 1 through 4 at a new location. 5. If the coat hanger moves freely in a complete circle, hold the supplied template up to the wall or ceiling and level it in the horizontal or vertical position.

FINISHING THE INSTALLATION PAINTING THE GRILLE AND FRAME After drywall is up, each HDFX frame and grille may be painted without the need for primer. For best results, use a spray gun or airless sprayer, thin the paint to prevent clogging of the grille holes, and apply several light coats instead of one heavy one. 1. Paint each grille and let it dry before installation. 2. Paint each frame and let it dry before installation. INSTALLING THE FRAME 1. Fill each wall cavity with insulatio

CONNECTING AND INSTALLING THE LOUDSPEAKER 1. At each loudspeaker, separate the loudspeaker wire so that at least 2 inches of each conductor are free. Strip away 1/4 inch of insulation from each loudspeaker wire. 2. On each set of loudspeaker connectors, press down the spring-loaded lever, insert the appropriate conductor, and then release the lever, as shown in Figure 15. Gently tug on the loudspeaker wire to make sure it is held in place. If not, repeat this procedure until it is.
