Wiring Two Channels To Single Speaker, So you’ve finally decided to get your favorite music throughout your house. What’s next? Where do you go from here? That depends upon your requirements and weather this will be an installation in an existing home or a music system in a new construction home.
First, you need to decide which rooms you would like to install your speakers. The installation will obviously be much easier during construction than in an existing home. Once you make the decision on which rooms to include, you have two choices; in-wall or in-ceiling.
In-ceiling speakers tend to draw less attention to themselves. In all but basic background music applications, in-wall speakers usually sound better, everything else being equal. In-wall speakers have other problems, however. They are usually harder to integrate aesthetically in the room. They also take up valuable wall space that can be used for art or furniture.
Typically, round speakers are use for in-ceiling installations and rectangular speakers are use when installing in the wall. Round speakers integrate better with other ceiling fixtures, such as smoke detectors and recessed light cans, which tend to be round as well. In addition, because most round speakers have coaxially located drivers, you are the same distance from both no matter where you are in the room. This leads to more even frequency response throughout the room. Rectangular speakers tend better suited to in-wall, rather than in-ceiling, applications.
It is best to keep the speakers two feet or so from adjacent walls or other boundaries that can cause response problems. Optimally, in wall speakers should be at, or close to, ear level. Place in-ceiling speakers so they are symmetrical with ceiling fixtures and the room.
Usually stereo pairs of speakers are use in each room. Another approach that works well is to sum the some signals into mono. You can then run the system in mono for most areas that use in-ceiling speakers. The mono approach allows you to get more uniform coverage, rather than standing under a speaker that is only playing the left channel for example.
You can also use one speaker for areas like small bathrooms and still get both channels of the music. There are speakers with dual voice coils and inputs for both the left and right channels on a single speaker that are also use for this type of application. It can demonstrated that the summed mono approach using a single, standard voice coil speaker usually sounds better, however.
