Loudspeaker fidelity depends on the
following three factors:
•
Loudspeaker accuracy
•
Loudspeaker placement
•
Listening room acoustics
Advanced JBL design features allow the
P81 and P941 to achieve exceptional
acoustical precision. However, proper
placement and listening room acoustics
have a significant impact on the per-
formance of the P81 and P941.
CAUTION:
•
The P81 and P941 should be installed
by a professional.
•
Installers must adhere to local build-
ing codes to ensure a proper installa-
tion. JBL is not responsible for any
possible damages caused by improper
installation.
LOUDSPEAKER PLACEMENT
The P81 and P941 are designed to offer
excellent performance in any listening
room or home theater system. Abide by
the following placement suggestions
for optimal results.
2-Channel or Front Left and Front Right
in a Home Theater System
The bulleted items that begin below
indicate important loudspeaker place-
ment considerations for 2-channel or
front left and right installations.
•
The speakers should be equidistant
from the primary listening position
and placed at least 4 feet away from
the side walls.
•
It is recommended that the angle
formed between the speakers and the
listening area be between 45° and 60.°
For example, if the speakers are 8
feet apart, the listening position
should be 8 to 12 feet from each
speaker. Refer to Figure 6.
•
When used as part of a home theater
system, excellent results can also be
obtained when the speakers must be
placed further apart due to a screen.

Surround Channels in a Home Theater
System
The bulleted items that begin below
indicate important loudspeaker place-
ment considerations for surround chan-
nel installations for home theaters.
•
When used as part of a 5.1-channel
music or home theater system, the
surround speakers should be placed
slightly behind the primary listening
position. Refer to Figure 7.
•
If there are several rows of seating,
place the speakers perpendicular
to, or slightly behind, the last row of
seating.
•
When used as part of a 6.1/7.1-
channel music or home theater sys-
tem, place the side speakers at the
sides of the main listening position.
•
If there are several rows of seating,
place the speakers perpendicular to
the middle row of seating.
