Vtx B18 - JBL VTX Series User Manual

6.2 - VTX B18

The VTX B18 is JBL Professional's next-generation single 18" subwoofer, designed to complement VTX full-range sound reinforcement
systems. The VTX B18 features JBL's new 2288H 18" woofer, engineered for improved linearity, increased sensitivity and extra-long
excursion. The 2288H is based on JBL's Differential Drive, dual voice coil, dual-gap technology, which delivers better heat dissipation,
lower power compression and wider dynamic range than conventional single-coil designs. The B18 incorporates JBL's patented 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 configurations. 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" high-performance woofer
design in a decade, engineered from the ground up to deliver trans-
parent, linear bass response down to 28 Hz. The 18" driver leverag-
es JBL's patented fourth-generation Differential Drive technology to
deliver maximum sensitivity 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 groundstacked 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 con-
figurations simply by selecting the appropriate speaker preset
and cabinet 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 grill
design, which minimizes exposed components and protects
the loudspeaker from extreme conditions. The enclosed grill
helps the system achieve a higher Ingress Protection (IP55)
rating.
