If you're looking for a truly immersive audio experience, 7.1 surround sound offers superior sound quality compared to stereo and envelops you in sound from all directions. It's an audio technology typically used in movies and video games for a premium surround sound effect.

7.1 Surround Sound and Gaming
We learned that the 7.1 system is perfect for movies, but is 7.1 surround sound good for gaming? In general, the realistic sound could be an amazing boost for people playing certain games while being downright disadvantageous for others.
For example, these sound systems are excellent for flight or race simulations. But the surround sound experience doesn't benefit shooters since the game engines use stereo systems, which means the 7.1 system would be disadvantageous to competitive shooters.
Whichever type of gaming you’re into, your best bet is to pick from an impressive selection of gaming speakers for personal computers.
Besides surround sound speakers, you can also opt for a 7.1 surround sound headset if you want a great gaming experience.

Most music is recorded in mono and mastered in stereo, which is why it sounds best when listened to in stereo. While you can try to stream music in surround sound, this usually makes the audio louder without improving clarity and often causes sound distortion.
So, the answer to the "Is 7.1 surround sound good for music?" question is, regrettably, a big no.
How To Place 7.1 Front and Rear Speakers
The speaker layout should follow the recommended pattern in order for the listener to be completely ensconced in the 7.1 surround sound. Also, keep in mind that installing a home theater system with eight channels provides much better results in large rooms than in small to medium rooms.
Various placement strategies work in situations that involve several speakers. Yet, the most common 7.1 surround sound system placement for realistic sound is the following:
- There is one center speaker
- A subwoofer goes in front of it, on a surface that’s lower than the center speaker
- Two speakers that are front channels go forward and slightly to the sides
- Two extra channels (speakers) are to the left and right of the listener
- Finally, two additional speakers are to be placed diagonally behind the listener

7.1 Surround Sound Alternatives
Alongside the 6.1 surround sound system, the 5.1 is the most common alternative to the 7.1 version. So what are the main differences between 5.1 and 7.1?
Offering two additional speakers to enhance sound quality, 7.1 surround sound systems build on one of the previous configurations, the 5.1. Thus, 5.1 systems contain five speakers and one subwoofer, whereas 7.1 systems have seven speakers and one subwoofer.
The standard 5.1 system setup has three speakers in front of the room (in the center, to the right, and left) facing the listener and two surround sound speakers in the back of the room.
If you’re still unsure as to which option better suits your needs, be sure to read our 5.1 vs. 7.1 in-depth review to learn more about the similarities and differences between these systems.
