another thing, pag malapit naman ako about 3 feet from it, well centered naman ang boses. pag lumayo nako dun na nawawala sa center.
You are experiencing a very well-known phenomenon in audio. What we hear from our system is a mix of direct sounds coming from the speakers and reflections coming from the sounds which bounce off the walls, floors and ceiling.
Reflections *may* have a negative effect on sq, including poor imaging, spectral balance, ringing, intelligibility, etc. These "bad" reflections are usually the first reflections. There can also be "good" reflections which tend to give a sense of space, for example. These are the later reflections.
Draw an imaginary equilateral triangle with your 2 speakers and the main listening position. The general rule is that if you go closer to the speakers (you go "inside" the equilateral triangle), there is much more direct sound than reflected sound. Thus, you remove the possible negative effects of reflections. Take note though that on the other hand, you also remove the "good" reflections.
