How to Choose a Ceiling Speaker

The size of the ceiling speaker is an important consideration. It should be smaller than half of the size   of the front speaker. For example, a ceiling speaker with an 8-inch driver should not be larger than   196mm in diameter. You can even get ceiling speakers with a depth of 160mm or a cutout diameter of   250mm. If you are using a ceiling speaker system with multiple small speakers, be sure to check the   specs of each unit.

When choosing the type of in-ceiling speaker, make sure you check the power supply for the speaker and its amplifier. If you're installing an active speaker, you can use the power supply nearest to the speaker or from a separate amplifier and receiver. Make sure the ceiling is deep enough for the wire to pass through. Otherwise, the speaker won't work properly. Moreover, you should also check the wire length and wiring of the ceiling speaker to ensure that it won't damage the ceiling.
