In ceiling speakers and in wall speakers are speaker systems that are mounted inside the wall cavity of a room and so are positioned out of sight of the people in the room, yet produce the same rich audio experience that you would expect from cabinet mounted speaker drivers. There are various reasons why people would choose to mount their speakers in their walls rather than the conventional way. The first benefit of doing so is that speakers that are mounted in walls, do not occupy precious living room space. The extra space can be used to position other furniture or for a television stand. If you are seeking a large open look in your living room, than wall mounted speakers can help accommodate this goal. Additionally, when speakers are set up this way, the wires and cables are stored out of sight, so there is no need to worry about tripping over these, or getting them tangled. In many cases and when the walls are made out of certain materials, the audio quality of wall and ceiling speaker can produce better quality sound.

When choosing wall mounted speaker drivers, the same parameters that you get with conventional speakers apply. In other words the speakers should be evaluated on their own merits. Common parameters include: power handling, the power ranges the speakers can receive from the amplifiers without problems. Efficiency or sensitivity, which is how effectively the speaker utilizes the received power and Frequency Response which is the range in the audio spectrum that the speaker is capable of. An ideal frequency response range is 20Hz to 20MHz which is the range of the average human ear.

One of the critical aspects when installing this type of speaker arrangement is the capturing of back waves that will get absorbed into the back wall if the speaker is not sealed correctly. This can lead to low quality sound that distorts and is uneven.

The mounting procedure is mostly an architectural problem. Solid planing before the sound system is install can lead to a greater chance of success. It helps if the wall has not yet been built, although it is possible to install speakers into an existing wall, albeit at a higher cost and with greater difficulty. When installing into an existing wall you must ensure there is nothing behind the target mounting point that could cause a problem such as electrical wiring. Holes need to be carved into these points and the wiring threaded into the right places. Finally, the grill is installed over the driver. The grill can be painted so as to blend into the color of the wall. Installing in ceiling speakers is not an easy process, so seeking out the help of a professional may be necessary if you lack the appropriate skills.
