CHAPTER 6 – PLACEMENT AND SETUP CONSIDERATIONS

The 

Project K2 S5800

loudspeaker

system is designed to be less
affected by room acoustics than
conventional imaging systems.
However, it is very sensitive to
overall symmetry, and proximity 
to walls, ceilings and corners.

Ideally, any listening room should
contain a combination of live sur-
faces (e.g., walls and windows)
and absorbent surfaces (e.g.,
drapes, carpets, upholstery). If the
distance from floor to ceiling is
short, it is preferable that one sur-
face has an absorbent covering.
With 

Project K2 S5800

, it is most

important to be able to accommo-
date the optimum listening area that
is defined by the 60° horizontal/
30° vertical coverage pattern of 
the horn.

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 on a vertical plane
with the horn (approximately 32 in/
80cm) as illustrated in Figure 2.

CAUTION:

Project K2 S5800

is a

massive system comprising materials
chosen for their density, with its
weight concentrated in a relatively
narrow area. Verify the integrity of

the floor surface before placing and
setting up the speakers. See 

Floor

Requirements.

If possible, the distance between
the speakers should be the same
as the distance between each
speaker and the listening area.
Angle the speaker in toward the
listener so that when seated, the
listener could look straight into the
center of the speaker (Figure 7). As
the distance increases between
the speakers, increase the inward
angle of the speaker.

The imaging qualities enable the
speakers to be placed relatively far
apart from each other. In addition,
the low-frequency alignment fea-
ture enables placing the speakers
near or even in a corner without
producing an overabundance of
bass. This corner placement ability
allows optimum performance even
in small rooms.

The 

Project K2 S5800

system can

operate fairly close to the wall.
Allow enough clearance between
the back of each speaker and the
wall to allow making the connec-
tions on the back of the speaker
(approximately 2"–3" is sufficient),
and to avoid interference with the
performance of the tuned port.

Remember that these speakers
weigh close to 185 lb (84kg) each
and cannot be easily moved.

FLOOR REQUIREMENTS

The floor in the location selected
for setting up the 

Project K2 S5800

speakers must be capable of sup-
porting a load of 185 lb (84kg).
Because of the coupling effect of
the stainless steel feet, a flat, hard
surface such as wood or linoleum
is preferable. However, the design
of the loudspeaker’s coupling sys-
tem, along with the speaker’s
extreme weight, should result in
excellent performance on any 
surface, even on carpets.

To prevent indentations on wood 
or linoleum floors caused by the
weight of the loudspeaker, always
utilize the enclosed coasters. Do
not set up the 

Project K2 S5800

system directly on a ceramic tile
floor; the concentrated weight
might cause the tiles to crack.
