A basic Home Theatre System may be made up of a television hooked up to a receiver which outputs sound through a pair of speakers. As stated before, the television is connected to the receiver via RCA Cables. The placement of the receiver is arbitrary. The length of the RCA Cable may determine where the receiver is placed with respect to the television. In regards to the television, it should be placed in the center and in front of the main viewing area.
Speaker placement is crucial for maximum sound.
The speakers should be placed equidistant from the television on either side as well as equidistant from the viewer. The speakers should be turned inward with the cones facing directly at the main viewing area. The sweet spot is that point in a room where the sound hits your ears at a higher volume level than if you were standing somewhere else. Sound travels in waves as was explained in the section about speakers. On a sinusoidal graph, the distance from the x, or time, axis to the top of the crest is called the amplitude.
