center channel speaker : Center Channel and Stereo Audio
Stereo audio was firstly designed to separate recorded sound into two channels( that is what the term” stereo” means), with left and right channel speakers placed in front of the room. Although some sounds come specifically from the left or right channel speakers, principle lyrics or dialog are mixed into both speakers.
With the lyrics mixed to come out of both the left and right channels, a” sweet spot” is created that’s equidistant between the left and right channel speakers. This gives the listener the vision that the lyrics are coming from a phantom center spot between left and right channel speakers.

Although this is an effective way to present lyrics, as you move the listening position from the sweet spot to either the left or right, indeed though the devoted left wing and right sounds stay in their relative positions mandated by the left and right channel speaker, the position of the lyrics will( or should) move with you.
You can also hear this effect by using the stereo receiver or amplifier’s balance control. As you telephone the balance control to the left or right, you can hear the lyrics change position consequently.
As a result, in a traditional stereo setup, since the lyrics are coming from both the left and right channels, you can not control the position or position( volume) of the center channel lyrics singly from the left and right channels.

Center Channel and Surround Sound
Surround sound provides an effective result to the center channel problem posed by two- channel stereo listening.
Unlike stereo, in a true compass sound setup, there’s a minimum of5.1 channels with speakers allocated as follows frontal L/ R, compass L/ R, subwoofer(.1), and devoted center. compass sound formats, similar as Dolby and DTS, point sounds that are mixed into each of those channels, including sounds specifically directed to a center channel. This encoding is handed on DVDs, Blu- shaft/ Ultra HD Blu- shaft Discs, and some streaming and broadcast content.

As a result of how sounds are mixed for compass sound, rather of having the lyrics dialog placed in a phantom center spot, it’s placed in a devoted center channel. Due to this placement, the center channel requires its own speaker. Although the added center speaker results in a little further clutter, there are distinct advantages.
Changing volume Situations Since the center channel is separated from the left and right frontal channels, its volume position can be changed without changing the volume situations of the left and right frontal channels. This comes in handy when compensating for dialog/ lyrics that are too low or too high in a music or movie soundtrack, as you can acclimate the volume coming out of the center channel speaker independent from the rest of the speakers.
Inflexibility Although compass sound has its own” sweet spot,” it provides a more flexible listening experience. While sitting in the compass sound sweet spot is desirable, as you move your listening position from left to right, the lyrics dialog will still appear to come from its center position( although at an angle off- center from the sweet spot). This is more like it would sound in the real world if a person was talking or singing in that position while you move around the room.

As a result, the center channel does not have a devoted center anchor spot and succumbs to the same limitations described for lyrics/ dialog in stereo setups.
