The Array Series Solution:
A Compact, Flexible
System For Professionals
Array Series is an optimized system which
combines precision engineered transducers
and advanced control technology for a level
of performance second to none. Since its
introduction these system products have found
favor around the world in a wide variety of
applications: musical theater, concert audio,
corporate A/V rental work, dance music club
installations and broadcast/film special event
support, to name but a few.
Optimized System Engineering
To optimize transducer integration, JBL
engineers turned to advanced signal processing
technology to assure smooth response and
phase integrity. Crossover filters, transducer
alignment, system equalization and protective
limiting are implemented to be completely
transparent, allowing the transducers to
perform to their maximum potential. Available
digital controllers offer the user a choice of
features and performance to complement any
installation or portable touring system.
The Sum Of Its Parts
Low Frequency Transducers
For Array Series, JBL engineers developed
the first-ever neodymium-based pro audio low
frequency transducer. This 335 mm (14 in.)
device features an advanced magnet structure,
used for high flux density and low overall
weight. Harmonic distortion is reduced through
the use of dual shorting rings
(one aluminum and the
other copper). Linearity is
maintained, even at high-
excursion extremes, with
the use of a 100 mm
(4 in.) diameter edgewound
aluminum ribbon voice coil. The audible result
is absolute clarity and definition in the
bass/low mid frequency region.
JBL’s exclusive VGC™ (Vented Gap Cooling)
technology is part of an optimized Thermal
Management System which makes efficient use
of both forced air and convective cooling.
Convection cooling is maximized by encasing
the compact, powerful neodymium magnet
within the diecast aluminum frame, engineered
to act as a large, efficient heatsink. This design
reduces thermal compression by as much as
60% compared to competitive products, allowing
Array Series systems to deliver higher sound
pressure levels at full dynamic range.
A glass fiber/paper composite cone is used
to achieve a greater stiffness-to-weight ratio.
The new cone formulation, along with its ribbed-
wall geometry, greatly reduces distortion by
minimizing cone break-up.
High Frequency Compression Driver
Array Series products use a 38 mm
(1 1/2 in.)
exit compression driver that features a
neodymium magnet assembly for maximum
magnetic energy and minimal weight. A damped
100 mm (4 in.) diameter pure titanium
diaphragm is positioned over JBL’s Coherent
Wave™ phasing plug for phase-correct
summing at the exit throat.

Horns
To achieve smooth, even dispersion at low
distortion in both the horizontal and vertical
planes, Optimized Aperture Flat-Front Bi-Radial
horns were developed for Array Series systems.
The family includes a 45° model with a uniform,
narrow coverage pattern segment that combines
well in arrays. 60° and 90° horns provide
accurate, consistent coverage
for non-arraying applications.

Upgraded Enclosures Now
Feature DuraFlex
™
Long term enclosure durability is assured by
13-ply birch hardwood construction, proven
joinery techniques and JBL’s rugged DuraFlex™
exterior coating. Structural integrity is enhanced
by internal steel braces which double as attach-
ment points for S.A.F.E.™ flying hardware
accessories. The enclosure’s sidewalls taper at
22.5° angles, matching horn coverage angles
for effective array construction.
For easy transport, two comfortable handles
are installed on the side walls. The 4892A
features a 35 mm (1 3/8 in.) pole mount cup
on the bottom surface, for use with Tripod
Speaker Stands. The grille is 16 gauge perforated
steel, lined with open-cell reticulate foam to pro-
tect against moisture damage and dust. Input is
through two paralleled 8-pole Speakon™
connectors, which access each transducer
component individually.
There’s An Array System
Designed For The
Only Application
That Matters- Yours.
13-ply, 19 mm (3/4 in) void-free, cross-grain hardwood construction for maximum
durability in fixed or portable applications.
100 mm (4 in) pure titanium diaphragm features JBL’s patented diamond sur-
round to reduce membrane stresses in the support structure. Aquaplas damping
reduces break-up modes and smoothes overall response.
VGC™ (Vented Gap Cooling) uses normal cone excursion to force air across the
voice coil for maximum heat dissipation, resulting in higher power handling and
reduced power compression.
Dual shorting rings, aluminum and copper, greatly reduce 2nd and 3rd order
harmonic distortion.
Neodymium magnet structure for light weight and high flux density. Black motor
structure is pressed into diecast aluminum frame which acts as heatsink for
effective convection cooling.
Large diameter vents prevent compression for linear output during high SPL
usage.
Integral steel braces accept S.A.F.E.™ (Secure Array Flying Hardware) for quick,
safe rigging.
4890A,4891A
Two-Way Single 355 mm (14 in)
Full Range System
These stage monitors use two configurations;
vertical format for minimal footprint, and hori-
zontal for minimal height to allow unobtrusive
presence on stage. A 600 x 400 horn that
rotates in the 4890A and 45° cabinet angles
provide optimum coverage for any application.
Linear response at high level satisfies even the
most demanding artist.
4892A,4892A-90
Two-Way Single 355 mm (14 in)
Full Range System
These compact packages exhibit outstanding
full range output and are capable of very high sound
pressure levels. Both deliver impressive performance, the 4892A as a
dedicated array component and the 4892A-90 for single system
applications. A 35 mm (1 3/8 in) pole mount adapter is standard.
4894A,4894A-90
Two-Way Dual 355 mm (14 in)
Full Range System
In situations where greater low energy is
required, the 4894A and 4894A-90 deliver.
They are the ideal system choice for outdoor
and larger venue applications where maximum
sound pressure level is required without
compromising fidelity. The 4894A can be used
as an array element and for side fill applications.
The 4894A-90 provides wider coverage from a
single enclosure.
4893A
Dual 355 mm (14 in)
Subwoofer System
