With the majority of modern TVs getting thinner and thinner, you probably have noticed built-in speakers are no longer delivering the best sound quality at all. That’s where a 2.1 or a 3.1 soundbar for improved TV sound watching comes in. But, what is the difference between 2.1 soundbars vs 3.1 soundbars?
The main difference between a 2.1 and 3.1 soundbar is that the 2.1 soundbar comes with a left and right channel as well as a subwoofer while a 3.1 comes with three channels, one on the left, another on the center, and the third one on the right plus a thumping bass subwoofer too.
Lackluster TV speakers are no help to anyone, so the best thing to do is to get that perfect soundbar so you can elevate your entertainment sound system. My TV set is connected to the Taotronics Sound Bars which delivers amazing quality sound for our tv. But, on my work station where I spend a lot of time writing, recording and editing YouTube videos, I have a pair of these monitoring bookshelf speakers for a perfect audio setup!
A little About Sound Bars
Soundbars also known as a media bar are types of loudspeakers that project the audio from a wide enclosure. Its appearance is very different from the loudspeakers as it is wider than it is tall. And the reasons for this being for acoustic enhancing purposes. Soundbars can be perfectly mounted below or above a display device such as a computer monitor or a television set.
In a soundbar you will find multiple speakers placed in one cabinet, this in fact helps to create a sound that is surround (though coming from one direction) as well as stereo effect.Usually you will also find that a separate subwoofer is also included within or may just be used to supplement the sound bar.
The most popular sound bar manufacturers are the following yamaha, Sonos arc, Vizio,Bose, Roku smart,Polk magnifi and Dolby atmos.
Benefits Of A Soundbar System
Sound bars are an all in one system that is meant to deliver high quality audio without taking a lot of space in your home as some external speakers would do.Sound bars are very good for people who place an importance on cable management as well as home decoration as they can be placed right under the tv set and connected wirelessly via bluetooth.
Sound bars have become very popular in the last 20 years ever since they were first created,not only because they are stylish and sizeable but also because they are budget friendly compared to speakers and home theaters.
What Is A 2.1 Soundbar And What Is 3.1 Soundbar?
A 2.1 sound bar is a soundbar with two speakers and one subwoofer,usually a left and right channel.The purpose of the extra speakers is not just to add some extra volume but it is instead to create a more truer surround sound experience.
With this soundbar those two or more speakers will provide you with a clear left and right channel of audio,giving you a great building block for your sound system although it will not improve the listening experience in a meaningful way.
The 3.1 channel soundbar has got a center channel,it comes with a separate speaker in the middle of it on top of its additional left and right end speakers.
This in fact provides much better dialogue as well as clarity to the sound as most of the dialog or voices come from the speaker that is in the middle.
Difference Between 2.1 And 3.1 Soundbar
Before I go deeper into the differences between these two systems the main obvious difference you will notice first is the size,the 2.1 soundbar being slightly smaller than the 3.1 soundbar.The size not necessarily in height but in width as the 3.1 has to accommodate a third speaker for the third channel.
A 2.1 channel soundbar is slightly smaller because it has got only two channels and one subwoofer,it comes with only two built in speakers.On the other hand a 3.1 soundbar is considered an upgrade for most because it includes three channels which is left,right and center as well as a subwoofer.
The other obvious difference between these two is that when you are listening the 3.1 soundbar you will have a much clearer dialogue because its center channel focuses primarily on dialogue audio.
However the 3.1 sound bar is not necessarily the better choice for everyone and both these soundbars have got their own benefits when it comes to setup.
Setup of 2.1 Soundbar And 3.1 Sound Bar
2.1 Soundbar Setup
2.1 setup is basic,you have got a left and right channel that are built into the soundbar with an external subwoofer.This will give you a clear left and right speaker sound although the sound wont be as great as a more advanced setup would be.
3.1 Soundbar Setup
This sound bar is a little bit different from the 2.1 soundbar when it comes to setup.Since you are adding a center channel speaker within this soundbar it will automatically add a more dynamic sound.
This one will not require you to add any rear speakers in order to get true surround sound like in 5.1 channels or the above sound systems.
With this 3.1 system you are adding more room filling sound as well as dimension with that one particular extra channel.This is the closest you will get to that surround sound feeling.
Basically as i mentioned above the 3.1 soundbar will give you much better sound quality as well as clarity with dialogue since the dialogue comes primarily from the center channel speaker.The 2.1 soundbar system will be a lot less clear and crisp because it will be mixed with sound effects as well as music.
