Mastering Surround Sound: 2.1 to 9.1 Explained
Imagine you have decided to set up a surround sound system, and you are going to run across numbers 2.1, 5.1, 7.1, 7.1.2, 9.1, etc. As you see them again and again, you may begin to realize what they actually are. What is meant by the different speaker channels?
Let’s get acknowledged about the details of the different speaker systems and what their channel structure actually looks like. For getting the sound setup you are looking for, click any of the links.
What Do The Numbers in Speaker Channels Mean?
The First Number (ex: The “7” in 7.1)
The first number of any speaker system configuration destines the number of principle speakers in the setup.
When it is about the main speakers, we refer to the front left, front right, center, and various surrounding speakers.
The Second Number (ex: The “1” in 2.1)
The second number of any speaker system configuration destines the number of subwoofers in the surround sound setup.
It is common to see a 1, which means there is one subwoofer in the setup, but you may come across a two now and then. While most surround sound systems could work great with one subwoofer, some people prefer the sound of two for their unique rooms.
The Third Number (ex: The “2” in 7.1.2)
The third number of any speaker system configuration destines the number of “height” of a speaker.
If two numbers are not enough, you may come across numbers like 7.1.2 or 9.1.2 in the home theater product search. While these numbers seem pretty complex, it simply gives room to define “height” speakers in the home theater surround sound system. Height speakers are usually located in the home theater room ceiling, but they could also be upward-firing speakers.

FAQs

If you need an even number of speakers, you will want to go with a 2.0 stereo system.

One 5.1 surround system has six channels, 7.1 has eight channels, 7.1.2 has ten channels, and 9.1 also has ten channels.
What is the best number for a home theater speaker channel?
The aptitude number of home theater speakers channels depends on your room. Especially the size. If you have a little room, you will want to go with a smaller number of speaker channels, and it will optimize a bigger room with a huge number of speaker channels.
However, a small room could benefit from speakers placed in the front, the sides, the back, and on the ceiling (unless it’s a particularly low ceiling). Typically, you will get a good sound with a large number of speakers optimally placed everywhere in the room, based on the size.
