Introduction
The WideLine loudspeaker system has been designed to pro-
vide a compact system that has unique power handling, fre-
quency response. Its primary uses include ballrooms, theatres,
night clubs, houses of worship, and small to medium size
events for the corporate and industrial markets.
WL2102 enclosures are constructed of lightweight cored-com-
posite and weigh 70 lb (31.8 kg). WL2102-w enclosures are
constructed of birch plywood and weigh 83 lb (37.7 kg). The
hardware allows for simple vertical splay angle adjustment of
0, 2, 3, 4, 5, 6, 7, 8, 9, and 10° between enclosures.
Two array frames are available. The Stacking Frame is for sus-
pended applications or stacking on top of QSC’s 215SB or
215PCM subwoofers. The large array frame is for suspended
or ground stack applications.
The WideLine system is suitable for stand alone applications
as a full range, articulate, high fidelity, sound reinforcement
product with the ability to reproduce almost any musical pro-
gram without subwoofers or bass modules. It has bass
response to 55 Hz (-3 dB) in a small format package. Its 3-way,
bi amp or tri amp design keeps required amplification to a min-
imum.
WideLine’s exceptionally wide dispersion practically elimi-
nates the need for “side” or “fill” hangs when used as the
main array. Its wide dispersion also provides enhanced cover-
age when used as a center cluster or as a downfill or under-
hang enclosure when used with larger format line array
systems.
Wide dispersion is accomplished with a 3 inch (76mm) dia-
phragm, 1.4” (36mm) exit neodymium high-frequency driver
mounted on a proprietary, patent-pending multiple aperture
diffraction-slot waveguide. This device is the ideal linear
source needed for wide angle line array performance.
Internal, mid-frequency shading can be switched to either 10”
(254mm) transducer. Both transducers handle the low-frequen-
cies, but only the non-shaded transducer handles the mids.
This provides smoother pattern control at the mid-high cross-
over. With selectable shading, the enclosures can be used as
house right or left by flipping the switch, not the enclosure.
WideLine users can also use a software tool called EASE
Focus to aid in the design and implementation of a WideLine
array. EASE Focus can calculate the number of enclosures
required for a given space (venue), determine the optimum
splay angle between those enclosures, calculate at what
angle to set the array frame in a single (variable) pick-point or
fixed suspension point application, and predict the acoustical
response and sound pressure levels throughout the venue in a
two-dimensional illustration. The software is available sepa-
rately; downloadable from the QSC website or contact QSC for
more information.
Like all QSC Audio products, WideLine design focuses on
accurate audio performance, rapid set-up, and reduced labor
requirements. Ease of transportation, assembly, use, and self-
contained rigging hardware make WideLine the clear choice.
