What's the difference between echo walls and traditional speakers?

Echo Wall is a simplified home theater system. It is the sound placed above or below the TV, which generally has intermediate frequency, high frequency and low frequency. The effect is that DSP simulates sound effects, which can only be simulated, but can't compare with the real effect.

For those who have a small space at home or want to improve the sound quality of TV, but don't want to install a full set of surround sound, echo wall is an excellent choice. The echo wall is very thin, and its length is about 1 m or more. Generally, they are installed on the wall or the cabinet under the TV, and some echo walls with bases can also be put inside.
