Echo walls are a great choice for people who have a small home or want to upgrade the sound quality of their TV by installing a surround sound kit. 

 Also call it sound bar, put in TV namely above or below acoustics, general medium frequency, high frequency, low frequency have, the effect is DSP analog sound effect, can simulate only, it is not as good as true effect. 

Bass is partially missing, a speaker playing full frequency signal will not take into account all the signals, other channel frequency is lost, if it is a real DTS or Dolby disc to play, then the echo wall effect will be much worse.

Echo walls are very thin, about 1 meter in length or longer, usually installed on the wall or on the cabinet under the TV, some have a base of echo walls can be placed under the TV.
