The storage speakers in front are generally placed as close to the center of the image screen as possible. Middle voice speakers have the greatest impact on the sound quality of the movie dialogue. In order to ensure that the dialogue is accurately positioned in the middle of the screen and the sound is well restored, it should be used by a separate speaker specially designed for the middle channel, instead of using ordinary bookshelf speakers or TVs Internal speakers instead.

The best place to place is the top of the TV (if the projection display screen is used in front), it should be as close as possible to the screen. If due to the restrictions of the room space, a more economical placement plan can be adopted, that is, there is no middle speaker. However, the working mode of the AV power amplifier should be set in the "illusion" channel mode, so that the information of the middle channel is released balanced from the left and right speakers. The sound is just in the center of the screen. The room is applicable. Of course, it is best to set the medium speaker.
