Of course, every instrument has its own dispersion pattern, but there are many things about the dispersion pattern that most instruments and the human voice share: They are sort of omnidirectional with more treble thrown to the front because the player or singer's own body blocks some treble energy to the back. Some instruments, such as trumpet, have a stronger front-to-back bias in the treble region, but others, like cymbals and drums, are pretty much omnidirectional right up to the high treble. String instruments are fairly omnidirectional. Your ears don't have to be in line of sight of the soundhole to hear the upper overtones, as long as you're in reasonable proximity of the soundboard or spruce top. Again, the guitarist's body blocks some of the back wave, but still, quite a bit of it will disperse backwards and reflect off the back and side walls, and the ceiling as well.
The Mirage speakers with their Omniguide disperse the sound very similar to the average pattern--omnidirectional with more sound thrown forward and somewhat upward. It really works. The timbre of some instruments (such as piano) is shaped significantly by how the instrument energizes the room.
One speaker design can't duplicate the individual dispersion patterns of each and every individual instrument and singer, but the Mirage Omniguide-based speakers largely replicate the core of that dispersion pattern that they share, and averages out the rest.
