Why choose two separate speakers over having both in a single enclosure?

One of the great joys in listening to music is when it sounds so real, you feel you could reach out and touch the artists. Stereo imaging is what makes this possible, and in order to create true stereo imaging, speakers need their space. Why? Audio engineers use stereo imaging to give the music spatial location and depth, so that it "comes alive" in your living room. If the lead guitarist of your favorite rock band stands on the left side of the stage, the audio engineer will mix the audio so that we hear the lead guitar from the left speaker a little louder and a split second before we hear it from the right speaker. Most experts agree the optimal distance between the right and left speakers should be about the same as the distance from either speaker to the listener (i.e. listener and speakers form the 3 points of an equilateral triangle). So if speakers in a single enclosure are separated by 18 inches or so, the optimum listening distance is an intimate 16 inches. A few feet further, and most of the imaging and depth are lost. So to enable proper stereo imaging for all sizes of listening environment, we needed to separate the speakers more than was possible in a single box configuration.
