6 - OVERVIEW

The VTX B18 is JBL Professional's next-generation single 18-inch subwoofer, designed to complement VTX full-range sound reinforce-
ment systems. The VTX B18 features the 2288H 18-inch woofer, engineered for improved linearity, increased sensitivity and extra-long

, technology, which delivers better heat dissipation,
®
lower power compression and wider dynamic range than con-
ventional single-coil designs. The B18 incorporates JBL's patent-
ed Slip Stream™ double-flared exponential low-frequency port
design to improve airflow and reduce audible turbulence, even
at maximum excursion. The B18 shares the industrial design of
the JBL's VTX A-Series products and has the same width and
suspension hardware as the VTX A8, allowing the two products
to be used together in a variety of flown or ground-stacked con-
figurations. The VTX B18 can be deployed in omni-directional or
cardioid configurations, in arrays of up to 16 enclosures.
TRANSDUCER DESIGN
The VTX B18 features JBL's first new 18-inch high-performance
woofer design in a decade, engineered from the ground up to deliver
transparent, linear bass response down to 28 Hz. The 18-inch driver
leverages JBL's patented fourth-generation Differential Drive tech-
nology to deliver maximum efficiency and power handling in a light,
compact design.
VTX A8 COMPATIBILITY
The B18 rigging system is compatible with the VTX A8 rigging sys-
tem, allowing B18 subwoofers to be suspended above an A8 array.
The VTX B18 rigging system allows for omnidirectional or cardioid
configurations in small and large-scale flown or ground-stacked ar-
rays. All VTX A8 suspension accessories are compatible and arrays
of up to 16 enclosures can be created.
CONTROLLABLE COVERAGE
The VTX B18 can be used in omni-directional or cardioid configura-
tions simply by selecting the appropriate speaker preset and cabi-
net orientation. Speaker connectors are available on both the front
and back, streamlining cable management in either configuration. A
switch on the rear input panel allows for selecting between channel 1
or 2 of the NL4 cable, minimizing cable requirements.
VTX BUILD QUALITY
The VTX B18 adopts the VTX A-Series' signature full-face grille de-
sign, which minimizes exposed components and protects the loud-
speaker from extreme conditions.
