What You Should Know About Surround Sound Speakers

It’s impossible to enjoy home entertainment without a high-quality sound system. Even when it comes to digital entertainment, such as movies and games, sound has an even greater impact on the overall experience than pictures. Surround sound systems have become the most popular in recent years. That’s interesting.

Basically, the goal is to create an immersive sound experience that is nearly identical to that of nature. Thus, a system with surround sound gets its moniker.

In the early days of film, surround sound systems were designed for movie theaters. With the help of surround sound technology, filmmakers were able to create a really immersive sound experience. In recent years, as home theater systems have improved and audiophiles’ demands for higher-quality audio components have gotten more exacting, surround sound systems have gained in popularity.

Technology of the Surround Sound System

Aside from proprietary standards like Sony’s DTS and Dolby Atmos, surround sound system technology is open source.

The stereo system was the only audio format available at the beginning. This meant that the audio could be realized using only two speakers (left and right). The AC3 sound format, sometimes known as 3-channel or 2.1, was introduced later and is still extensively used in CD tracks today. For deep, low-frequency sound, the AC3 included a third channel, which was solely connected to the sub-woofer.

After the AC3, the next logical step was the increasingly popular 5.1- and 7.1-channel audio formats. It is possible to use other formats such as 9.2 and 11.2, albeit they can only be used in professional settings (such as in movie theaters and at home).

Audio codecs are broken up into numerous independent channels in a surround sound system. Various speakers play different frequencies for each channel. The audience can then enjoy a true surround sound experience by placing these speakers all around them. It’s necessary to broadcast these channels on the go in order to compile them into one cohesive audio track.

Subwoofers for surround sound

7.1 (8-channel) surround sound is most commonly utilized in home entertainment content like Blu-ray movies and video games, but it can be scaled down to 5.1 if necessary (6 channel). The term “5.1” refers to the use of five different channels to represent the use of five different surround speakers. There is only one sub-woofer channel in the (.1) part of the description. As a result, there are six audio channels in all.

Speakers are divided into four broad types in each format. These include the front speakers, middle speakers, rear speakers, and a subwoofer.. A closer look at these speakers will help us understand what they have to say.

The Subwoofer

The subwoofer is the system’s heaviest and most powerful component. Typically, it’s housed in a huge wood cabinet with several wide openings for air flow. Deep, low-frequency sound waves go through a subwoofer, which is why it’s called that. The bass of an audio recording is produced by low-frequency sounds. The channel for the subwoofers is only dedicated to enhancing the bass. It is unable to produce high-frequency sound because of its design.

The subwoofer is the most noticeable component of any audio system due to the vibrating sound it creates with great force.

Some subwoofer-less setups use a woofer instead. Compared to a subwoofer with a diameter of 30 inches, this is significantly larger. Subwoofers have the drawback of producing more noise than they do sound. Because they can cause items to collapse over in the living room, these vibrations are best left outside or at concerts.

Front Speakers

The left and right front speakers are located in the foreground. Most of the time, these speakers are slightly larger than the other satellite speakers. They have a wide frequency range, which means they can create sound from the lower end of the spectrum to the upper end of the spectrum.

Front speakers in surround sound media material provide sound that comes from the picture’s front. In respect to the audience’s left and right sides. The audio track from a video game or movie can also be heard through the front speakers.

In today’s home theater systems, soundbars have replaced the speakers in the front and center positions. Multiple speakers are positioned horizontally in such a way that they serve as the front and center speakers on a soundbar.

Speakers for the left and right front speakers come in a variety of designs. Floor standing or bookshelf models are both viable options. However, the most important thing is that they both work effectively together with the center speaker, regardless of whatever you choose.

There are three main considerations when it comes to purchasing speakers:

  • The dimensions and design of your living space
  • You’ve set a spending limit.
  • Your speakers can be used to play what kind of music (movies or music)

Center speakers

There is only one center speaker in a 5.1 setup and it sits right above the crowd. The center speakers of a 7.1 system are two speakers placed on either side of the audience.

The front and rear speakers dwarf the center speakers in terms of size. They have a wider frequency range than the front speakers and are often tuned lower. Media such as movies and video games have a central speaker for most dialogue and monologs.

Speakers in the Back Surround

Surround left and right speakers are used to create the rear surround speakers. The size should be similar to or slightly smaller than the front speakers. They’re positioned directly behind the audience, on the opposite sides of the auditorium from the front speakers.

High amplitudes and wide frequency response are the hallmarks of these speakers, which are capable of producing a wide range of sounds. The rear speakers receive the majority of the ambient sound and special effects.

Other Speaker Arrangements for a Surround System

As previously indicated, there are systems with more than eight channels. As many as 13 audio channels are possible. In spite of this, the overall structure is the same. The front surround, center, subwoofer, and rear surround will never go out of style. The number of speakers and channels for each of the different categories could fluctuate.

In a 9.2 surround system, for example, there can be two subwoofers, four channels for the front surround, one center-surround, and four speakers for the rear.

The more channels employed, the more vivid and powerful the surround effect becomes.

Conclusion

Knowing the purpose of each speaker in your home theater system may not seem vital, but knowing this information is essential if you want to place them correctly. Make use of the information in this article to assist you in selecting the surround sound system
