 5.1 or 7.1 – Which is Better for an A/V Receiver?

While deciding which surround sound system is perfect for an A/V receiver, you need to consider multiple factors. Keep in mind that an A/V receiver will support all the channels that are available in a surround system. However, it will be better to go for a receiver that includes all the outputs for the 7.1 system.

You need to note that a 7.1 receiver can easily be used for a 5.1 surround system. There are also AV receivers that can recognize whether it is connected to a 5.1 or 7.1 system. The advantage of a 5.1 sound system is that it comes at a relatively affordable value.

What About Availability of Audio sources for 7.1 System?

Most types of Blu-Ray don’t come with any unique soundtrack. This is due to the reason that it lacks 7.1 audio tracks and has been mixed for the 5.1 surround sound system. It should be noted that the latest movies come with high-quality sound in the form of Dolby TrueHD, Dolby Digital Plus or DTS HD master.

There are many audio technology companies including DTS and Dolby that have come up with codecs for producing 7.1 sound from the 5.1 soundtracks. This makes them play 7.1 channels for movies mixed with a 5.1 sound system.

7.1 Surround Sound – Is It Really Better?

When there will be an addition of surround-back speakers, it can provide better sound. This means that upgrading to 7.1 from 5.1 is less superior compared to a soundbar with a 5.1 system. When the soundtracks are mixed with the 7.1 system, the results can be great. This means that there will be no noticeable improvement in the sound immersion.

5.1 surround sound – Is It Possible To Get 3D Sound?

If you are looking to have an immersive and realistic sound, a 7.1 surround setup can be the ideal choice. Keep in mind that to have a true 3D experience, you will require a different speaker arrangement on your audio technology. With Dolby Atmos, the sound can bounce off the ceiling. We can say that a 5.1 setup can produce 3D sound. However, it can be limited. For a true 3D experience, it will be better to combine it with Dolby Atmos.

5.1 or 7.1: The Final Decision

The following are the factors that let you choose between a 5.1 or a 7.1 system.

  • With a 5.1 system, there will be a standard surround system in small and large rooms.
  • In small rooms, a lot of speakers can lead to a muddy sound. You can use a 7.1 system if the room is over 350 square feet in area.
  • 1 surround sound systems need compatible A/V receivers. Also, it requires codes to upgrade to a 7.1 system from a 5.1 system.
  • To create a better sense of immersion and atmospherics, 7.1 systems employ surround backs. If there is not much space behind the listening area, there will not be much difference between the sound quality.
  • Soft furnishings including carpets and couches can prevent sound reflection. Whereas hard materials like flooring, tables, and desks can disintegrate the additional speakers’ effect.


Basically, if you have a small to medium room, you go for a 5.1 system. Even if you have a large room and there is a budget constraint, you can go for a 5.1 system. But we would recommend you go for a 7.1 system when you have a large room. Otherwise, the sound clarity will be lost with the 5.1 system. The 7.1 system is a thing of the future as more and more soundtracks and movies are made for the 7.1 surround system.
