5.1 or 7.1? Which sound system is right for me?

Audibly better sound or costly gimmicks - opinions differ on the question of whether it should be 5.1 or 7.1 in the home theater. In fact, there are a number of things to consider when answering this question. We go through point by point and clarify when 7.1 can be worthwhile and when it is better to stick with the smaller solution.

5.1 or 7.1 - these are the differences in the list

In one case the home theater system consists of 6 and in the other case of 8 speakers. With the 7.1 configuration, two additional surround speakers are set up or mounted behind the seating or listening area - often Surround backs called. That is already a important purchase criterion mentioned: Can the two surround backs be accommodated in the living room?

General judgments about the minimum room size are difficult, because a lot depends on the room conditions and the equipment. A 7.1 sound system usually only achieves audible sound improvements from one Room size of more than 30 m2.

Like the satellites on the side, the surround backs are installed at least at head height. In most cases, wall or ceiling mounting is therefore an option. It is important that they are not mounted too close to the seating area. Otherwise the surround sound will suffer rather than improve. In addition, there should be around 10 cm of space between the speakers and the wall.

For the remaining channels with subwoofer, front loudspeakers (center and main loudspeakers) and the side surround loudspeakers, the same rules apply to 5.1 and 7.1 sound systems: The loudspeakers should be aligned with the listening area and positioned as symmetrically as possible to one another.

The requirements for the AV receiver

The AV receiver must support the available speaker channels. For this, corresponding outputs on the receiver are necessary for the "discrete" speaker channels.

You can use a 7.1 receiver use it without hesitationto power a 5.1 configuration. The outputs for Surround backs then remain unused. Some receivers automatically recognize that the two channels are not used for 7.1, with others you have to set this in the menu first.

Quite relevant for the purchase decision: 7.1 receivers cost more than devices that only support 5.1. In return, you usually get a high-quality receiver with a good amplifier and sufficient connection options.

How important are genuine 7.1 audio sources?

You should be prepared for the fact that numerous Blu-rays do not support 7.1 sound - at least in the German soundtrack. If there is no 7.1 sound, it means that the sound engineers did not mix separate soundtracks for the two rear speakers. With newer films, however, you will occasionally come across 7.1 formats. Examples of these formats are:

However, this does not mean that the two surround backs inevitably remain mute with sound that has been mixed for 5.1. Both Dolby and DTS have developed codecs that distribute the existing audio information to the two rear speakers. Examples of such surround sound polishers are Dolby Pro Logic IIx and DTS-Neo 6.

Buying tip: If you want to drive a 7.1 system, make sure that the receiver supports 7.1 refurbishers.

Does a lot help a lot? Is 7.1 really audibly better?

What can you look forward to with the two additional surround speakers in your back? In any case, you come a little closer to the goal of enveloping, differentiated and authentic surround sound. A clear improvement can be heard, especially when there is sound material that was produced specifically for this installation. The prerequisite for this, however, is that the home cinema offers the necessary space for a 7.1 sound system. If you squeeze a 7.1 system into a small room, you may even achieve a worse effect than with 5.1.

Conclusion: 5.1 or 7.1 is primarily a question of space

  • 5.1 systems create a spatially well-defined home cinema sound in both small and large rooms of over 30 m2.
  • The two additional surround backs of a 7.1 system improve the surround sound and increase the precision of the surround effects
  • As a rule, sound improvements can be achieved with 7.1 from a room size of 30 m2.
  • Not all films are mixed for 7.1. Codecs such as Dolby Pro Logic IIx, however, prepare sound for 7.1 systems, which was originally mixed for 5.1, by forwarding the sound information to the two rear speakers.
  • 7.1 means higher costs when purchasing speakers and AV receivers.
