Channel rails are often required by local building codes for safety reasons as well as for improved aesthetics in suspended 2'x2' or 2'x4' tile ceilings. They distribute the ceiling speaker's weight to the ceiling support structure, reducing the likelihood of tiles sagging under the weight of the speaker.
