Caution: Unsafe mounting or overhead suspension of any heavy load can result in serious in-
jury and equipment damage. Mounting of speakers should be done by qualified persons in ac-
cordance with all applicable local safety and construction standards. Be certain to follow the
instructions provided by the manufacturer of the mounting bracket. Before selecting a mount-
ing bracket, be certain that it is capable of supporting the weight of the speaker to be mounted.
Notes:
All measurements unless otherwise stated made anechoically in a 4p environment at 2 meters,
referenced to 1 meter by inverse square law.
The reference measurement microphone position is located perpendicular to the centerline of
the low and high frequency transducers at the point 63.5 mm (2.5 in) below the center of the
high frequency diaphragm.
Acoustic loading provided by the listening room increases maximum SPL capability and low
frequency bass extension as compared to stated anechoic values.
Distortion measurements performed with the input voltage necessary to produce the stated
A- weighted SPL at the stated measurement distance. Distortion figures 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 performance improvements. 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 specification unless otherwise stated.
