Niles Audio HDLCR manual Concealing Speaker Wire, Pulling the Cable, About Interior Walls

•When drilling holes in ceiling joists, drill in the center of the joists and try to locate the hole near the end of the joist.

IMPORTANT: DO NOT DRILL THROUGH A GLU-LAM OR LOAD-BEARING BEAM WITHOUT THE DIRECTION OF YOUR CONTRACTOR.

•Try to line the holes up perfectly, because it makes pulling the wire much easier. A good technique is to snap a chalk line across the face of the studs or against the bottom of the ceiling joists. Then work backward so that you can always see the holes you have already drilled. Paying careful attention to this will save you time later on.

PULLING THE CABLE

Pull the cable in sections (from the stereo to the volume control, from the volume control to the speaker). Start with the longest sections and use leftover wire to complete the short sections. Also consider the following wiring tips:

•If you plan to pull many rooms at the same time through a central route, walk off the Distance to each destination, add a generous “fudge factor” for turns and other Obstacles, and then cut off each section, so you can pull a bundle of wires at once.

•When running the wire further than 4-1/2 feet from a hole in a stud or joist (e.g., open attic space, going up walls, etc.), be sure to fasten the wire to the joists or studs using cable clamps or appropriately-sized wire staples. The wire should not have large sags in it, nor should it be too tight.

•Try to protect the wire from being stepped on in attics or other unfinished crawl spaces. Use guard strips, raceways, or conduits to protect the cable. Consult the local building code for special requirements in your area.

ABOUT INTERIOR WALLS

Interior walls in almost all North American residences are hollow, so they are easy installation sites for flush mounting speakers and routing new speaker 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 horizontally in the ceilings and floors. The space between the studs and joists is used for the home’s wiring and plumbing.
