Controlled Horizontal Dispersion
Your Quests launch a 30 degree dispersion pattern when
viewed from above. This horizontal dispersion field gives
you a choice of good seats for the performance while
minimizing interactions with side walls.
See Figure 1
.
Make sure both speakers stand exactly at the same
vertical angle, otherwise the image can be skewed or
poorly defined. The wave launch of both speakers is
extremely accurate in both the time and spectral domain
and, consequently, small refined adjustments can result
in noticeable sonic improvements.

As you can see from the illustrations, your Quest
speak-
ers project a controlled dispersion pattern. Each Quest is
a four foot line source beginning two feet above floor
level.
See Figure 2
. This vertical dispersion profile
minimizes interactions with the floor and the ceiling.
