used in a surround-sound setup that is responsible for reproducing vocals
and other centrally located sounds. The speaker is generally magnetically
shielded to prevent interference with CRT based screens. While many will
argue that a center channel speaker is not necessary, in cases with a lot
of off-axis movie watching, it greatly helps keep dialogue centered on the
screen. Care should be taken to keep the center channel timbre matched to
that of the front speakers, which is important to provide a smooth transition
as sounds move from one speaker to the next.
