Vienna Acoustics Klimt The Kiss - Manual (Page 7)

The second stage is much more gradual and one that may not be noticed
immediately. This is the fifty to approximately three-hundred hour period.
During this final period of break-in, there is a further refinement in the micro-
dynamics or inner detail that will become more defined. In other words, the
presence of the musicians becomes more intimate. It is during this period that
final setup should be completed.
3.2 Positioning The Music and The Kiss
While there are several recommended methods used in proper speaker setup,
the only process that we believe in is one that includes listening. If you are not
listening to the speakers, it will be impossible for you to know whether you are
making the correct adjustments.
The first area of consideration when setting up a large scale, sophisticated
speaker system such as either The Music or The Kiss is the distance between the
speakers. Unfortunately, it is our experience that people leave their speakers
positioned far too close together to take full advantage of the scale and size of
presentation that a modern reference speaker system is capable of. The basic
rule to follow is to position the speakers with at least an equal distance between
the left and right channels as you are from them. For example, if you are three
meters away from the speakers, the speakers should be at least three meters
apart.
The second area of setup is commonly referred to as toe-in. With a two-piece
speaker design, this process requires more care than the typical single cabinet
design. The simple starting rule is to have the bass or lower cabinets aimed
approximately one to two meters behind the center or listening position (A)
while the top or Music Center is aimed approximately one-half this distance (B).
See the following image:
Caution: Before attempting any movement of the Music Center, be sure that
the locking bolt on the rear of the speaker is loosened. It is possible to force the
movement of the Music Center when it is locked down. Doing so will
permanently damage the pivoting hardware.
