Surround sound center speakers are exactly what they sound like. Whether you’re running a simple 5.1 channel receiver or something far more complex, having the right speakers for the right stereo locations is important. That being said, center channel speakers are of particular importance because when it comes to shows and movies, the most important sounds are likely going to be right in front of you.
The purpose of surround sound center speakers is to create a balance between the stereo left and stereo right. More specifically, replicating the intended audio space for the content you are listening to can go a long way in improving immersion, and taking advantage of high-fidelity sound.
