1 JBL Eyebolt System
Located on the top (and bottom) is our standard JBL eyebolt
system to accommodate ceiling attachment (and floor
mounting system, see Foot Kit, page 19), when required.
2 14” LF/MF Transducers
Each 14-inch, LF (Low Frequency) and LF/Mid carbon-
fiber cone transducer features our patented dual-coil, dual-
gap Neodymium Differential Drive (NDD™) technology
for 1/5
th
the weight of conventional ferrite transducers with
twice the power handling. Moreover, each transducer is
driven by its own 600 watt D-class (digital) amplifier.

3 Thermomaster
®
Vents
Each respective baffle vent, woofer motor, and basket are
all linked via the same thermal transfer path for maximum
heat dissipation. Taking heat away from the voice coil
effectively reduces power compression. The harder the
system works, the better it cools.
4 2430 Compression Driver
The JBL 2430 neodymium large-format compression driver
has a 1.5-inch exit and 3-inch voice coil with 100 watt
power handling. The revolutionary neodymium motor
structure results in an extremely compact and lightweight
HF (High Frequency) transducer, weighing only 2.5 lbs.
The JBL 2430 driver is powered by an internal 100 watt
linear amplifier.
5 Aluminum Waveguide
The aluminum waveguide effectively couples the JBL 2430
driver to the outside world. It works with the LF/MF and
LF transducers and our Filtered Array Technology (FAT™)
to achieve a constant 80
°
x 80
°
horizontal and vertical
coverage pattern.
6 Integrated Baffle
Our integrated transducer baffle and inertia grounding
straps are designed to lock all the components together,
maximizing acoustic output. The entire baffle area acts as
an open thermal window through which heat is allowed to
escape.
7 SMC Enclosure
The rear enclosure, fabricated from SMC (Sheet Molding
Compound), is in the form of a 2
nd
-order geometric design
for inherent strength, acoustic architecture, and transparent
aesthetics.
SMC Grille (not shown)
It looks like cloth, but it’s actually an anti-resonant, SMC-
reinforced, expanded steel grill, with an enhanced high
frequency spreading effect.
