VRX900 Line Array
Addressing the growing need for a small format professional sound system, JBL developed the VRX932LA and VRX928LA Constant
Curvature Line Arrays for sound rental companies, fixed installations, Musicians and DJ's looking for the ultimate in performance and
portability. Featuring the performance of high end line arrays in two compact 8 inch and 12 inch formats. It is affordable, flexible and
provides outstanding coverage and coherence. The VRX900 series shares components with the JBL VERTEC®Line Array Series, the
worldwide touring industry standard. It is perfectly suited for use in smaller venues and small to medium sound reinforcement projects.
Delivering extraordinary power handling, clarity and flexibility, the VRX900 Line Array speakers feature the hallmark of all JBL products
- Stunning, legendary JBL sound.
Constant Curvature Array
The challenge in designing a world-class line array is to create a
controlled, coherent coverage pattern regardless of the number of
cabinets used in the array. JBL’s Constant Curvature Array Design does
that and more. The VRX waveguide mounts three compression drivers on
a continuous arc enabling them to work together acoustically as if they
were a single driver, while dramatically increasing the power handling
and acoustic output when compared to a single driver system.
Additional enclosures can be added creating an uninterrupted,
continuous arc with all of the drivers working together seamlessly as if
they were one driver on a very long waveguide. This innovative
technology provides unprecedented output coherence and stunning,
clear high-frequency sound quality regardless of the configuration.
Amplitude Shading
Covering a venue with a smooth, consistent sound field is key
to the success of any professional sound reinforcement project. The VRX
accomplishes this with JBL’s Array Configuration Selector, a convenient
series of switches on each enclosure that controls the output of each
high-frequency section in the array. With the VRX’s amplitude shading
you can set the upper enclosures in an array configuration to deliver
more output for reaching a distant balcony while the lower enclosures
can be ‘shaded back’ with less output for the front rows of the venue.
Each section of the venue can be fine tuned for a balanced, seamless
overall coverage pattern.
VRX900 Subwoofer
For applications requiring the sonic and practical advantages of integrating the subwoofers into the flying array JBL offers
the VRX918S and the VRX915S, two compact, high power, suspendable subwoofer systems using 15 inch and 18 inch
Differential Drive®woofers in front loaded vented enclosures. The VRX918S was designed specifically for use in arrays
with the VRX932LA, as the VRX915S complements perfectly the VRX928LA. Both subwoofers are equipped with a top-
mounted, threaded, M20 socket that can receive the optional SS4-BK adjustable pole.
VRX915M Stage Monitor
The VRX915M is a dedicated, compact and lightweight 15 inch touring-class floor monitor. Its symmetrical designed
enclosure enables convenient left-right orientation. With its low stage height and JBL's latest neodymium-magnet
transducers, it delivers world class performance in the most demanding applications.
Array Tool
The VRX932LA and VRX928LA array tools provide visual help for the user to better understand and deploy a VRX900 Line
Array. It can be found here: http://www.jblpro.com/vrx/ARRAYTOOL.HTML . Acoustic performance can be quickly assessed
by simply creating a two dimensional view of the environment the VRX900 system would be used in. The effect of adding
systems to the array and adjustments of the Array Configuration Selector can be quickly analyzed.

Pole Mount
To create a small, compact non-flying system, the VRX may be mounted on a tripod. For
greater power and low-frequency extension, one or two VRXs may be pole-mounted over
their companion subwoofer, such as JBL’s SRX718S, VRX918S, or VRX915S.
Configurations
Suspension and Rigging
Ease of set up and takedown is critical to ensuring high quality sound reinforcement that meets both time and cost
restrictions. JBL’s exclusive integral rigging hardware for the VRX900's allows the enclosures to be quickly and
securely locked to one another by simply swinging a hinged bar into place and securing it with the included quick
release pins. The optional VRX-AF or VRX-SMAF array frame attaches to the rigging hardware of each enclosure
providing an easy to use, elegant suspension system for flown arrays. A second array frame may be installed at
the bottom of an array for applications where the system must be aimed down sharply.
Construction
VRX900 Series enclosures are constructed with premium quality birch plywood. Coated in JBL's rugged
DuraFlex™ finish and heavily braced the systems are extremely durable, not to mention rigid and
resonance free. The heavy duty steel grilles are internally lined with acoustically transparent foam to
provide additional driver protection.
Differential Drive®Woofers
Sound reinforcement professionals constantly ask for more power but less weight so JBL designed the VRX’s
drivers with much less weight than comparable drivers and yet significantly increased its power handling and
output. Super lightweight neodymium magnets positioned inside the voice coil of each driver, a key feature of JBL’s
patented Differential Drive woofer design, reduce the massive steel top plates, back plates and pole pieces found
in the 'magnetic circuits' of conventional loudspeakers. The VRX’s dual voice coil design delivers greater power
handling while maximizing the performance of each driver. An integrated heat sink ensures excellent heat
dissipation and consistent, reliable performance. Overall, the VRX weighs less, has more power capacity, lowered
istortion and lower power compression than any comparable system.
Dual Angle Pole Socket
JBL’s dual angle pole sockets allow great flexibility in aiming the enclosure. By selecting the socket that best
directs the sound towards the listeners, unwanted acoustic reflections are reduced and overall system
performance is improved.
Ground Stack
For reaching bleacher and stadium seating from ground level, the
VRX’s ingenious cabinet design allows it to be ground stacked in
configurations of up to 4 enclosures delivering all of the power,
clarity and control of a full flown line array system without the
additional labor and expense.
Fly your VRX900 Array
VRX900 line arrays and subwoofers may be suspended using the
VRX-AF and VRX-SMAF array frame. For fixed installations, 10mm forged eyebolts
may also be used. See the VRX900 User Guide for details.
Single Cabinet
When configured for smaller venues, or musicians working alone, the
compact size, portability, light weight and stunning performance of the
VRX allow it to be used as a single cabinet two-way utility speaker system
that can be conveniently mounted on a tripod.
