Sometimes we can often hear enthusiasts boasting: "My sound field is not only beyond the speaker, but even breaks out of the wall." This sentence is like a layman hearing. For experienced friends, there is just a little exaggeration. Usually, in the performance of popular music, you can occasionally hear that a musical instrument sounds outside the speaker; and when classical music performance, you often feel that the width of the orchestra has exceeded the width of the two speakers. Rand the side wall. Many enthusiasts have this experience and do not need to spend more. As for breaking the wall, I am afraid that it will rely on a little imagination. At least, the location of the sound field that can be seen with imagination can be considered the real sound field. We can't see things outside the wall. It is difficult for us to be sure it is there. Therefore, the width of the sound field is actually only within the wall. You can fully experience this feeling from the 1812 prelude just now. If the 1812 prelude you hear, the sound is tightening in the middle of the two speakers without exceeding the sides of the speaker, then you'd better invite a knowledgeable enthusiast to diagnose your audio and see if there is something wrong there.
