5.1 speakers are more complex than 2.1 speakers since they have three extra speakers (a center speaker and two rear speakers) totaling five.  The center speaker is for voices and dialogue. In contrast, the two rear speakers are surround-sounds whose purpose is to output extra sounds. The two front speakers act like normal speakers to output normal sound.

2. Both speakers use surround-sound speakers to alter the angles and direction of sound waves. Sound waves concentration depends on the direction surround speakers are facing, which is a common feature in both speakers. For 2.1 speakers, surround speakers are inbuilt, making angle alteration difficult.

Factors To Consider When Buying 2.1 Or 5.1 Speakers

Some major factors should be considered when deciding whether to get a 2.1 speaker or a 5.1 speaker. They include;

The Durability Of The Speaker System

Durability is an important factor since a good quality speaker should last for years. One needs to consider a system that can upgrade instead of replacing it with a new one. In this case, a 5.1 speaker will be the best as it is easier to get entry-level systems for an upgrade.

Speakers Calibration

Calibrating and labeling of speakers is also vital. It is important because most speakers are similarly created with identical features. In many speaker systems, it is impossible to tell the difference between surround speakers and rear speakers as they all look alike. Some unique features that can be used to tell the difference would be an added advantage. A poor cable connection of these speakers may cause electrical accidents. In this case, most 5.1 speakers have calibration features, with some internal while others are external.

Space Availability

Available space and room size are other factors to consider because all the sound systems should be accommodated without creating unnecessary sound. 2.1 systems are best when a small room is involved as they have few features. If the room is large and can accommodate additional surround speakers, then 5.1 speakers are the best choice.

Price Of The Speakers

Price is a reasonable factor to consider when deciding whether to get 2.1 speakers or 5.1 speakers. 2.1 speakers are generally cheap and affordable, with good quality models going for less than 100 dollars. On the other hand, 5.1 speakers are expensive though cheaper models in the market depend on quality. 2.1 speakers may be cheap, but they do not provide an upgrade option. This will call for a new sound system if an upgrade is required. On the contrary, 5.1 speakers have a wide range of products that can be used to upgrade therm.


Both speakers connect to the TV by use of an HDMI cable. One needs to ensure that their TV has an HDMI port and supports a soundbar system. Most TVs are compatible with 5.1 speakers, which calls for additional Blu-ray players. With this, one can connect 5.1 speakers to experience the surround speaker’s sound. Their compatibility issues make people prefer using 2.1 speakers, whereas others opt to invest in a good quality TV. With this, they can use soundbars of their choice.

Ease Of Installation

5.1 speakers can be very challenging when setting up the soundbars is concerned. They have five channels that require a connection, whereas 2.1 speakers have only two speakers. They can be easily installed as they do not have specific locations. In the 5.1 speakers, surround speakers are separately placed from the rear speakers to ensure the required sound output is achieved. Both speakers have Bluetooth connection. Those who have TVs with Bluetooth connections shouldn’t worry about installation issues as their connection is automatic.

Why Use 2.1 Or 5.1 Speakers?

Speakers allow one to create a high definition sound to support the television speakers’ low profile audio. They help in creating a home theater feeling without detracting the look and feel of a television. Both speakers are portable and can be used for outdoor activities to connect to their phones to play music. Both speakers are of low-profile and can be easily packed up for use in another room. 


Many speakers do not guarantee the best sound output. Some 5.1 speakers are from low-quality manufacturers and produce low-quality sounds despite having five channels. On the other hand, some 2.1 speakers include high-quality inbuilt speakers creating excellent sound output. It all depends on the speaker’s drivers and also how well the soundbar is enclosed. Apart from sound quality, other factors such as room size, price compatibility and ease of installation are considered when deciding which speaker is better between the two.
