JRX115
Key Features:
䉴
JBL 15" low frequency driver with
a 64 mm (2½in) diameter edge-
wound ribbon voice coil which
provides more cross-sectional wire
area in the voice coil gap than
round wire designs, for greater effi-
ciency 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 the
frequency response to deliver
coherent summation in the
crossover region.
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™ high-
frequency 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 performance.
䉴
SonicGuard™ protects the high-
frequency 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.
䉴
Dual-angle pole-mount socket
allows the speakers to tilt 10° for
more uniform audience coverage.
The JRX115 is a portable, fifteen-inch, two-way speaker system designed
specifically for applications in live music, music playback, and reinforce-
ment of speech. With the smooth, natural sounding mid-range of the sys-
tem, the JRX115 does a great job projecting live vocals, solos and speech.
The extended lows and great top-end make it at home for music playback
in DJ applications or anywhere live sound reinforcement is needed.
