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.
By adding the SPK8 accessory to this soundbar you can create a 4.1 Soundbar – left, right, surround left, and surround right channels with an external subwoofer. The two surround channels give the system a traditional surround sound experience.
