When it comes to soundbar setups, a 2.1 setup is a basic setup. You have a left and a right channel that are built into the soundbar, with an additional external subwoofer. A soundbar with a 2.1 setup will definitely be a step up from your TV’s built-in audio. You’ll have a clear left and right speaker sound, although it won’t provide a highly dynamic surround sound experience that a more advanced setup would. If you’re looking for the lowest cost upgrade to TV’s built-in speakers, a 2.1 soundbar is a great choice for you.
A 3.1 soundbar sounds a little bit different than a 2.1 soundbar, and are typically a little more expensive. Since you’re adding the center channel speaker(s) within the soundbar, it will add a more dynamic sound. You won’t be adding any rear speakers to get a true surround sound experience, like in a 5.1 channel or above sound system, but you are adding more room-filling sound and dimension with the extra channel. It definitely gets you closer to a surround sound feel.
As mentioned, a 3.1 channel soundbar will give you better sound clarity with dialogue, since dialogue primarily comes out of the center channel speaker. Dialogue, on a 2.1 channel system, will be mixed with sound effects and music, which ends up being a little less crisp and clear than on a 3.1 system.
By adding the SPK8 accessory to this soundbar you can create a 5.1 Soundbar – left, right, center, surround left, and surround right channels with an external subwoofer. These have become a game-changer in the market because they can completely replace a traditional surround sound system. The two surround channels give the system a traditional surround sound experience.
