“Audio performance coupled with dispersion, size and weight make the
WideLine-10 our weapon of choice. This week our system went from an arena
comedy show, to an outdoor rock & roll show, to a corporate national sales
meeting with exceptional sonic results.”

WideLine-10 Line Array System
WL2102 Features
- 3" (75 mm) diaphragm compression
driver on patented 140° multiple aperture
diffraction slot waveguide – a near ideal
vertical line source
- 139 dB SPL peak acoustic output
- Bi-amp or tri-amp operation
- Dual 10" (250 mm) long excursion, high
power, low-frequency transducers
- WL2102 cored composite construction
reduces weight to 70 lb (31.8 kg),
enhances weather resistance
- WL2102-w birch ply construction lowers cost
with a 19% weight gain (83 lb, 37.7 kg)
- Captive box-to-box rigging hardware
The WideLine-10 has proven itself in venues
ranging from festivals, ballrooms, theaters
and nightclubs to concert halls, houses of
worship and arenas. The WideLine high-frequency
section consists of a 3" (75 mm)
diaphgram, neodymium magnet compression
driver, mounted on a patented multiple
aperture diffraction slot waveguide that
produces the ideal linear source required for
proper line array performance, along with
exceptionally wide horizontal coverage.
The 3-way design operates in either biamplified
or triamplified mode. Both 10"
(250 mm) diameter low-frequency transducers
cover low frequencies while only
one extends to the mid/high crossover
point. The single midrange transducer
assures smooth response both on and off
axis at the transition to the diffraction slot
loaded high frequency section.
Biamplification, with passive components producing the frequency response shading of the low-frequency drivers, allows fewer amplifier channels and simplifies wiring. Triamplification with active electronics controls the required low-frequency shading with greater precision and is recommended where maximum output and optimal sound quality are desired.

16 ohm low-frequency transducers optimize allocation of amplifier channels. In bi-amp mode the LF/MF sections of four enclosures present a 2 ohm load that can be powered by one amplifier channel. In tri-amp mode the LF and MF sections of up to eight enclosures can be powered by a single two channel amplifier.
The WL2102 cored composite enclosure material is lightweight and highly weather resistant: net weight is less than half that of some conventional designs.
The WL2102-w is constructed of industry standard birch plywood at a substantial cost savings for more price sensitive applications where the ultra light weight and extreme weather resistance of the cored composite enclosure are not required. Birch construction results in a 19% increase in weight; 83 lb / 37.7 kg vs. 70 lb / 31.8 kg for the cored composite WL2102.
WideLine-10 rigging hardware allows both
composite and plywood enclosures to be
arrayed together. Two array frame models
let you choose the right tool for the job.
The larger Fly Grid can accommodate flown
arrays of up to 12 enclosures with a design
factor of 10:1 and ground-stacked arrays of
up to 8 boxes. The smaller Stacking Frame
also does double duty, suspending arrays of
up to 6 enclosures with a 10:1 design factor
and allowing ground stacks of 4 boxes.
Vertical splay angles between adjacent
enclosures are adjustable in one degree increments
from two to ten degrees and can
also be set at zero degrees (i.e. front faces
parallel). All array hardware is “captive”
– permanently attached to the enclosure.
There are no loose parts to misplace.
WL218-sw WideLine Subwoofer

The WL218-sw is a premium, high-performance, dual 18" (460 mm) subwoofer designed for flying or ground stacking. With an impressive combination of punch, low-frequency extension and accuracy, the WL218-sw is an ideal companion for the WideLine-10. The WL218-sw is easily flown along side the main array for powerful and stunningly accurate low-frequency output. The AF218-sw is a simple, heavy-duty array frame constructed of welded, aviation-grade 6061-T6 aluminum: it will suspend up to 8 WL218-sw subwoofers with a 10:1 design factor. For ground stacking, interlocking feet and recesses are machined into the enclosure’s end caps.
Extremely musical yet powerful, the WL218-sw offers plenty of “punch” while maintaining ample extension so musically important and satisfying fundamentals are solidly and accurately reproduced – the result of carefully balancing transducer characteristics, cabinet volume and port tuning. The 18" (460 mm) woofers have double layer spiders and triple roll surrounds for extended and controlled excursion at extreme power. The 4" (102 mm) voice coils are wound on fiberglass formers to prevent deformation at high operating temperatures, and are extensively vented to reduce power compression. An aluminum demodulating ring is employed for low distortion.
Ample port area allows massive amounts of air to move freely with minimal turbulence or “chuffing”. The ports are arranged so as to eliminate asymmetrical loading of the woofers, which can result in distortion and voice coil failure related to rocking-modes.
Transport and handling were also given high priority. No matter how the box is deployed, one of the dozen handles will be where it needs to be. The included transport dolly attaches to the front of the enclosure with an easy-to-use yet roadworthy snap-on attachment mechanism and provides rugged 3.5" (89 mm) casters plus complete protection to the grille and transducers. An optional padded soft cover provides additional protection from the rigors of the road.
