Notes:
All measurements unless otherwise stated made anechoically in a 4
π
environ-
ment at 2 meters and referenced to 1 meter by the inverse square law.
The reference measurement microphone position is located perpendicular to the
centerline 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 capa-
bilities and Low Frequency Bass Extension as compared to stated anechoic val-
ues.
Distortion measurements performed with the input voltage necessary to produce
the stated “A” weighted SPL level 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 product improvement. New mate-
rials, production methods, and design refinements are introduced into existing
products without notice as a routine expression of that philosophy. For this rea-
son, 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.
