Generally, a center speaker is added so that the sound comes from the middle position, making it feel like singing at the front door. However, adding a center speaker cannot achieve this effect. All sounds are emitted from this speaker, and the treble, midrange, and bass are all mixed together. There is no sense of hierarchy and it is very complicated. It is better to add a DSP to adjust the sound field than to add a center speaker. The effect is far better than adding a center speaker. If it is an original speaker, there is no need to add it. Because DSP needs to add a power amplifier to connect. Hope this helps. Liuzhou Dongfangzhiyin Car Audio Modification Shop respectfully hopes to adopt it. The center speaker serves as a positioner for the entire sound field. For example, sometimes when listening to music, you may feel that some sound effects are a bit messy in the front, rear, left, and right. A center speaker can well position an orderly sound field. @2019
