[. . . ] Consult the local building code for special requirements in your area. Concealing Speaker Wire in Existing Walls This is actually a fairly simple task if you restrict your choice of speaker locations and wire routes to the interior walls or ceilings of your home. Interior walls in almost all North American residences are hollow, so that it is easy to flush mount speakers into them and route new speaker cable around the house. What you see when you look at the painted wall board, plaster, or paneling is only the skin of the wall. Behind the skin is the skeleton; twoby-four wood or metal "studs" running vertically from the floor to the ceiling in walls and two-by-six or larger "joists" running horizontally in the ceilings and floors. In between the studs and the joists is the space for the wiring and plumbing of your home. They must insulate the house from the heat and cold outside, so they are stuffed with insulation. The national building code requires that the hollow wall space in exterior walls be broken by a horizontal stud placed between the vertical studs. This "fire blocking" makes it very difficult to retrofit long lengths of wire. In some areas of the country the exterior walls are constructed Installation Fundamentals 10 Speaker Location plate (the horizontal 2x4 or 2x6 laid across the vertical studs) to the volume control location, back up to the attic, across the attic, and finally down another wall plate to a J-Box in the wall behind the stereo system itself (See Figure 8). 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 60Hz 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 three feet away. To find exactly where an electrical cable is routed, try inspecting the inside of the wall by turning off the breaker for a particular power outlet or switch, removing the cover plate and switch or receptacle, and shining a penlight into the wall. If you have access to an attic or basement space you can quickly see which part of the wall space is free of obstructions (See Figure 9). Installation Fundamentals 11 Volume Control Location Stereo Location Figure 8 of solid masonry, and have no hollow space for speakers or wires. Start by examining all the possible routes you might take to run the speaker wire from the speaker to the volume control and back to the stereo. Use a stud sensor or other device to locate the internal structure of the wall. A typical route would be: from the speaker location in the ceiling, across the attic, then down through a top Unobstructed space for speaker wiring Figure 9 When you don't have access above or below the wall, try to estimate the existing wire and pipe locations from the positions of electrical outlets and plumbed fixtures on both sides of the wall. Take a look at the outside of your house too, sometimes conduit, vents or drain pipe will be visible that give useful information. Choose the route with the fewest potential obstacles. If your house is built on a slab or you are wiring between two finished floors, look for baseboards which could be removed and replaced with the wire behind them. Doorjambs can be removed and often have enough space for speaker wire all the way around the door (See Figure10).
