JRX225
Key Features:
䉴
Dual JBL low frequency drivers
with a 64 mm (2.5 in) diameter
edgewound ribbon voice coil
which provides more
crosssectiona l wire area in the
voice coil gap than round wire
designs, for greater efficiency
and power handlin g.
䉴
JBL 2414H-C 25 mm (1 in)
polymer diaphragm
compression driver improves
high frequency performance as
well as system realiability .
䉴
The advanced network
topology crossover design
shapes frequency response and
delivers coherent summation in
the crossover region.
䉴
High-voltage capacitors and
inductor s with massive cores
and heavy gauge wire enable
the crossover network to
handle high power without
saturating.
䉴
Progressive Transition™ high-
frequenc y waveguide provides
superior coverage control,
reduced distortion, and
smoother frequency response.
䉴
The rugged, acoustically
superior enclosure is
constructed from
19 mm (¾in) MDF (Medium
Density Fiberboard) using
advanced adhesives and
mechanical fastener technology
for extreme durability and
improved low-frequency
performanc e.
䉴
SonicGuard™ protects the high-
frequenc y driver from excess
power without interrupting the
performanc e.
䉴
Non-resonant, all-steel handles
are used .
䉴
Attractive 18-gauge hexagon
perforate d, steel grille protects
component s from damage.
The JRX225 is a portable, dual fifteen-inch, two-way speaker syste m
designed specifically for applications in live music performance and
music playback. The dual fifteen configuration is especially useful for
application s in which additional low-frequency power and extension
is needed but adding a subwoofer to the system is not practical.

1. “Power Capacity” and “Peak Power Capacity” ratings are based on the average and peak power capacity of product
samples subjected to a 100 hour power test using random noise with a 6 dB crest factor, in accordance with IEC
standards.
2. “Frequency Range” and “Frequency Response” are based on half-space conditions.
3. Height dimension includes feet.
JBL continually engages in research related to product improvement. Some 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
