The principle of Surround systems
- Many Surround systems are based on the Stereo-triangle in the 1950s, they formed with the two speakers form an equilateral triangle.
- That is, Two speakers stand at a distance of about 2 m, each of 30° to the left and to the right of the direction of view of the listener.
- All other speakers are placed at the same distance to the listener, so that they are arranged on a circular line.
- The Position in the middle is referred to as the "Sweet Spot". For this listening position, the audio is optimized. In front of and behind the sound is still OK, the side you Spot, however, the Sweet, the inaccurate localization and space impression.
- As a "speaker base" refers to the connection line of the two speakers in a Stereo triangle.
- Many Surround setups can be found in the recommendation ITU-R BS.775-3 of the International Telecommunication Union.
- The Usual spelling of the speaker arrangement is the number of front speakers and behind it, separated by a slash, the number of rear speakers. Frontal, an additional Subwoofer is used, it is separated by a dot.
- "3/2.1" means that three are wide-band speakers in front and two behind the listener. A Subwoofer is placed close to the speaker base. In the case of Dolby Digital well-known 5.1-preparation is, for example, a 3/2.1-System.
- The best space of sound principles, such as Higher Order Ambisonics and wave field synthesis, however, have no standardized loudspeaker set-up. Here is a high number and as homogeneous as possible, the distance between the speakers is optimal.

Mono plus Mono Surround (1/1) is prepared in a loudspeaker at 0° and at ± 110°. The two Mono Surround speakers are fed with the same Signal. Therefore, it is referred to as the "1/2".

In the case of quadraphonic in the 1970s, the Scheibner-Array is either used. Here, the speakers are at ± 45° and ± 135°. So it is a 2/2-list.

Or the Dynaquad arrangement is used. Here, the speakers are at 0°, ± 90° and 180°. Both quadraphonic arrangements are basically the same, you need to turn only 45°.

In the so-called "LCRS Surround" (3/1) in addition to the Stereo Setup with loudspeakers at ± 30° is also a speaker at 0° and one at 180°. This list will occasionally be used for Dolby Surround Material.

In the 2+2-speaker system (2/2), also known as "Two-channel stereo plus 2 surround" is called, expands the Stereo triangle to two Rear Speakers at ± 110°.

A similar speaker set-up is used since 1975 for Dolby Surround (3/1): The Stereo-triangle-adds a Center speaker at 0°. Two Surround speakers are not exceptionally placed at the same distance, but 60 to 100 cm behind the Sweet Spot, slightly above the head. You radiate only frequencies from 100 Hz to 7 kHz, are fed with the same Signal and should not be on the Sweet-Spot oriented.

If you add to the classic 5.1-establishment of a speaker at ±70°, so the results in the 7.1-installation (3/4 of the way.1). The two added speakers are to be considered as a Surround speaker. Dolby Pro Logic IIx builds on the 7.1 set-up.

A further 7.1-installation (5/2.1) is recommended for SDDS-Sony Sound. Here, the speakers are in 0°, ± 22,5°, ± 45° and ± 135°. Thus, the localization of phantom sound sources works the front over a much larger area, and also the localization behind the listener compared to 5.1 and 3/4.1-installation improved.
