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 cen-
terline 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 level from 100 Hz to 20 kHz.
2 Describes Anechoic (4 ) low frequency response. Acoustic Loading provided by the
listening room will increase low frequency bass extension.
3 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 stat-
ed frequency range.
4 Power Non-Linearity figures based on the "A" weighted deviation from linear increase
in SPL with linear increase in input power (ie: power compression) measured after 3
minutes of continuous pink noise excitation at the stated power level.
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.
