Mounting Specifications:
The LSR6325P-1 has built-in mounting points for use
with industry-standard mounting hardware.
The mounting points are located on the rear panel of
the speaker system. The four threaded holes accept a
1/4" diameter machine screw with a pitch of 20 threads
per-inch. The length of the screw should be a total of
3/8th inch plus the thickness of the mounting bracket.
Hole Pattern:
Caution: Unsafe mounting or overhead suspension of any heavy load can result in
serious injury and equipment damage. Mounting of speakers should be done by quali-
fied persons in accordance with all applicable local safety and construction standards.
Be certain to follow the instructions provided by the manufacturer of the mounting
bracket, be certain that it is capable of supporting the weight of the speaker to be
mounted.
Notes:
All measurements unless otherwise stated are made anechoically in a 4
π environment
at 2 meters and are referenced to 1 meter by the inverse square law.
The reference measurement microphone position is located perpendicular to the cen-
terline of the low and high frequency transducers, at the point 70 mm (2.7 in) above
the center of the woofer.
Acoustic loading provided by the listening room increases Maximum SPL capabilities
and Low Frequency Bass Extension as compared to stated anechoic values.
Distortion measurements are performed with the input voltage necessary to produce
the stated “A” weighted SPL level at the stated measurement distance. Distortion fig-
ures refer to the maximum distortion measured in any 1/10th octave wide band in the
stated frequency range.
JBL continually engages in research related to produce improvement. New materials,
production methods, and design refinements are introduced into existing products
without notice as a routine expression of that philosophy. For this reason, any current
JBL product may differ in some respect from its published description, but will always
equal or exceed the original design specifications unless otherwise stated.
