A method of setting a sound bar, for setting, by using a controller, an output volume and an output timing of a speaker of each of a center channel, a left channel, and a right channel accommodated in the sound bar, the method comprising:

• receiving, by a controller, from a user, an installation position of a sound bar with respect to a display device forming a home theater system together with the sound bar;
• determining, by the controller, when the received installation position of the sound bar is to a left of a below-and-center position or an above-and-center position of the display device, the output volume and the output timing of the speaker of each of the center channel, the left channel, and the right channel by delaying the output timing of the speaker of the right channel from the output timing of the speaker of the center channel by a delay time T and delaying the output timing of the speaker of the center channel from the output timing of the speaker of the left channel by the delay time T, and by reducing the output volume of the speaker of the right channel from the output volume of the speaker of the center channel by an attenuation volume V and reducing the output volume of the speaker of the center channel from the output volume of the speaker of the left channel by the attenuation volume V;
• determining, by the controller, when the received installation position of the sound bar is to a right of the below-and-center position or the above-and-center position of the display device, the output volume and the output timing of the speaker of each of the center channel, the left channel, and the right channel by delaying the output timing of the speaker of the left channel from the output timing of the speaker of the center channel by the delay time T and delaying the output timing of the speaker of the center channel from the output timing of the speaker of the right channel by the delay time T, and by reducing the output volume of the speaker of the left channel from the output volume of the speaker of the center channel by the attenuation volume V and reducing the output volume of the speaker of the center channel from the output volume of the speaker of the right channel by the attenuation volume V;
