Step 1

Buy a 5.1, 6.1, or 7.1 surround sound system. The .1 refers to the use of a subwoofer and the 5, 6, or 7 refer to the number of speakers. The more speakers, the greater level of sound detail.

Step 2

Set up the system with 3 speakers in front around the TV and 2, 3, or 4 speakers behind the seating area depending on what type of surround sound system you have.

Step 3

Arrange the 3 front speakers like so:

Place the middle speaker under the TV on a stand or rack and angle it slightly upward, directing it towards the place where you will be sitting. If you must place the speaker on or above the TV, angle it downwards and raise the side speakers for a more even sound.
Angle the side speakers in a slight arc around the place you will be sitting so that all 3 speakers are the same distance away. Preferably, the speakers should be aimed at your head for a better sound and stuck in the ground to reduce vibration and improve bass.
If your speakers are to be mounted, place them in a straight line below the screen and mount them correctly.

Step 4

Arrange the back speakers like so:

For a 5.1 audio system, place the back 2 speakers in the back of the room near the sides.
For a 6.1 audio system, place the 3rd speaker in the middle of the room on the back wall.
For a 7.1 audio system, place 2 speakers in the back on the side walls and 2 spread across the back wall.

Step 5

Place the subwoofer on either side of the front center speaker for a smooth sound. If you have large speakers and large subwoofer, try placing the subwoofer in the place that you will be sitting and walk around the room, listening for the best bass. When you find that spot, place the subwoofer there.
