Notes:
All measurements unless otherwise stated made anechoically at 2 meters and refer-
enced to 1 meter by the inverse square law.
The reference measurement microphone position is located perpendicular to the center
line of the mid and high frequency transducers, at the point 55 mm (2.2 in) below the
center of the tweeter diaphragm
1 Mean SPL from 100 Hz to 20 kHz.
2 Describes anechoic (4p) low frequency response. Acoustic loading provided by the lis-
tening room will increase low frequency bass extension.
3 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 fre-
quency range.
4 Power nonlinearity figures based on the A-weighted deviation from linear increase in
SPL with linear increase in input power (i.e., power compression) measured after 3
minutes of continuous pink noise excitation at the stated power input.
JBL continually engages in research related to performance improvements. New mate-
rials, 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.

persons in accordance with all applicable local safety and construction standards. Be
certain to follow the instructions provided by the manufacturer of the mounting brack-
et. Before selecting a mounting bracket, be certain that it is capable of supporting the
weight of the speaker to be mounted.
