Using room treatments correctly, you should be able to hear information from EVERY direction, if it's in the recording. With most pop recordings, (that have little depth, and are "panned" mono music from a 128 channel console, with digitally synthesized 3 dimensional ambience, if you're lucky), IT GENERALLY STARTS FROM THE FRONT OF THE SPEAKERS, AND WIDTH GOES A LITTLE OUTSIDE THEIR LATERAL SPACING. Height should present instruments/singers with the proper "size" and height dimension. Sometimes their head can be several feet in diameter, with ultra-close miking and dynamic compression/limiting. THE BEST AUDIOPHILE RECORDINGS SHOULD IDEALLY TAKE YOU TO THE PERFORMANCE (at the microphones' position, period..."like being there".
