JBL Pro JRX125 Data sheet

JRX125

Key Features:

䉴

Dual JBL low frequency drivers
with a 64 mm (2½ in) diameter
edgewound ribbon voice coil
which provides more cross­sectional wire area in the voice coil
gap than round wire designs, for
greater efficiency and power
handling.

䉴

Ferro-fluid cooled compression
driver with titanium diaphragm
improves high frequency
performance as well as system
reliability.

䉴

The advanced network topology
crossover design shapes frequency
response and delivers coherent
summation in the crossover region.

䉴

A “Quasi 3-Way” design offers the
extra bass for which a dual fifteen
system is designed, but without
sacrificing performance in the
critical mid-range. The upper
woofer produces mid-frequencies
and bass, while the lower woofer
concentrates on bass only. The
reduction in mid-range phase
cancellation greatly improves mid­range sound quality and coverage.

䉴

High-voltage capacitors and
inductors with massive cores and
heavy gauge wire enable the
crossover network to handle high
power without saturating.

䉴

Progressive Transition™ high­frequency waveguide provides
superior coverage control, reduced
distortion, and smoother frequency
response.

䉴

The rugged, acoustically superior
enclosure is constructed from
19 mm (¾ in) MDF (Medium
Density Fiberboard) using
advanced adhesives and mechani­cal fastener technology for extreme
durability and improved low-fre­quency performance.

䉴

SonicGuard™ protects the high­frequency driver from excess
power without interrupting the
performance.

䉴

Non-resonant, all-steel handles are
used.

䉴

Attractive 18-gauge perforated,
steel grille protects components
from damage.

Dual 15 Inch
Two-Way
Speaker

The JRX125 is a portable, dual fifteen-inch, two-way speaker system
designed specifically for applications in live music performance and music
playback. The dual fifteen configuration is especially useful for applications
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 exceed
the original design specifications unless otherwise stated.
