Front call absorption, pls explain theory...


This weekend I decided to experiment with absorption on the front wall between my speakers. I placed 2 pretty thick pillows on the wall and was very pleased with what I heard:

-more holographic presentation of music especially vocals
-better layering of instruments in sound stage, I could more clearly visualize the varying depths of the instruments, perhaps helped by the fact that voices were presented more forward

Being the nerd that I am, I want to know what is the theory or technical explanation of whats happening. Or maybe I am better of being blissfully ignorant and enjoy the improvement?? :) Thank you in advance for helping me understand more about room acoustics.

What's happening is that; when the reflections are close to the original sound source, the timing between the original sound and the reflected sound is too close for the brain to process as separate sounds, so it sounds smeared (not correct). By absorbing some of the early initial reflections your allowing yourself to hear things more clearly.
