CHAPTER 6
Placement and Setup Considerations
The Project K2 S9900 loudspeaker system is designed to be less affected by
room acoustics than conventional imaging systems. However, it is still sensitive
to overall symmetry and proximity to walls, ceilings and corners.
Ideally, any listening room should contain a combination of live surfaces (e.g.,
walls and windows) and absorbent surfaces (e.g., drapes, carpets, upholstery).
If the distance between the floor and ceiling is minimal, it is preferable that one
surface has an absorbent covering. With Project K2 S9900, it is very important
to be able to accommodate the optimal listening area that is defined by the
100-degree horizontal/60-degree vertical coverage pattern of the horn.
In order to obtain the best stereo effect, the speakers should be placed at an
equal distance from the listening position.
• The distances to the right and left speakers are determined by the relationship
between the distance from the listening position to the speakers and the angles
of the speakers. The imaging qualities enable the speakers to be placed
relatively far apart from each other, but this weakens center imaging, such as
vocals. Increasing the inward angle of the speakers toward the listener will
improve the center imaging.
• The listener should be centered in front of the speakers, and furniture should
be of an appropriate height so that when the listener is sitting, the ear level is
about the same height as the high-frequency horn (approximately 36-inch/90cm),
as illustrated below.
