Introduction dens or living rooms; as main or surround speakers in home theaters. Thank you for choosing a Performance In-Wall Loudspeaker from Niles. With proper installation and operation, you’ll enjoy years of trouble-free use. The PR or Performance group of in-wall loudspeakers offers speakers expressly designed for an optimum balance of performance and value.
Moisture Resistant Construction The PR loudspeakers are suitable for use in high moisture environments. The drivers are impervious to moisture; the grille is made of powder-coated aluminum, and all exposed hardware is made of stainless steel. However, the speakers are not waterproof and direct contact with water should be avoided. Absolutely Flush to the Wall Appearance The unique mounting system of the PR loudspeakers powerfully clamps the frame to the bracket, sandwiching the wall material between them.
Speaker Wire Use 2-conductor speaker wire when connecting PR speakers to your receiver or amplifier. For most applications, we recommend you use 16 or 18 gauge stranded wire. For wiring runs longer than 80 feet (25 meters) we recommend 14 gauge stranded wire. When you run wire inside walls, special jacketing (CL-2 or CL-3) is required to both protect the wire and for fire prevention. In some areas conduit is required.
Placement for Varying Listening Positions If you want the freedom to sit anywhere in a room facing any direction, and/or find that you prefer the “all around you” sound of some car stereos to a conventional “sound stage” facing you, consider the speaker placement techniques professional installers use in restaurants and bars. They place speakers in an array around the listening area, so that the music is always surrounding you, regardless of the direction you face.
Running the Speaker Wire in New Construction If you have doubts about whether you are capable of installing a Niles PR loudspeaker in your walls, consult a Niles dealer or professional installer. They have special tools, techniques, and experience to make the impossible possible. The installer can provide you with an estimate before any work is done. Scheduling and Preparation Plan to schedule the speaker wiring after the electrical wiring is finished.
Volume Control Location Speaker Location Figure 4 Stereo Location Identify where all of your electrical, phone, and TV wiring is likely to be and plan to route around it all. You can accidentally induce 60 Hz hum on your speakers if you run your speaker wire right beside electrical wire for more than a few feet. Try to keep speaker wire running parallel to power cables at least 3 feet away.
Stage One: Before Drywall is Hung. Insulating the Wall Cavity. If feasible, fill the wall cavity with insulation at this point. Attach the wings to the bracket by snapping them into the sides of the bracket. The wings can be shortened by breaking them along the scored lines if their length will interfere with a corner or eaves. You can mount the bracket horizontally or vertically (See Figure 8). Screw one side of the assembled bracket with wings to the stud using one of the supplied screws.
IMPORTANT: Before you cut into any wall, review the sections on running wire and speaker placement. 1. Drill a 1/8” pilot hole just barely through the wallboard or dry wall (1/2” to 5/8” deep in most homes) about an inch below the center of your proposed speaker location (an inch to the side if you are mounting the speaker horizontally). BE VERY CAREFUL NOT TO DRILL THROUGH EXISTING WIRES, PIPES, OR STRUCTURE. IF YOU FEEL ANY EXTRA RESISTANCE AS YOU ARE DRILLING, STOP.
1. Separate the speaker end of the two-conductor speaker-wire run to free at least 2” of each conductor. 2. Play some music with the amplifier or radio set to Mono. 3. Listen to the richness of the bass and the loudness of the sound. 7. Place the speaker baffle Figure 13 in the frame by inserting the tabs at the base of the speaker baffle into the corresponding holes in the frame and pushing the speaker forward until the snaps engage. (See Figure16) Figure 1 2.
Removing The Speaker If the grille is already installed, remove it by using a bent paper clip or the tip of a corkscrew and pulling it away from the frame. 1. Carefully grasp the tweeter housing by placing your thumb and forefinger in the indentations provided. 2. Rotate the tweeter housing either clockwise or counter clockwise as required. The mechanism is indexed at equal intervals so that both speakers in a pair can be adjusted equally.
