The WideLine features an open, natural sound quality and exceptionally wide 140° horizontal coverage pattern - the widest of any line array system currently available.

WideLine is a three transducer system and can be operated in either biamplified or triamplified modes. Both 10" diameter low-frequency transducers are used to cover the lowest frequency range. One driver covers only low frequencies while the range of the other extends through the mid frequencies to the mid/high crossover point. The use of a single midrange transducer allows the horizontal coverage pattern to remain as wide as possible and assures smooth response both on and off axis at the transition to the diffraction slot loaded high frequency section. Biamplification uses passive elements to affect the required frequency response shading of the low-frequency drivers and offers reduced amplifier channel counts and simplified wiring. Triamplification allows the required low-frequency shading to be controlled with greater precision via active electronics and is recommended where maximum output and highest sound quality are required.

The WideLine's 16 ohm per transducer lowfrequency impedance optimizes allocation of amplifier channels. In biamp mode the LF/MF sections of up to four enclosures can be powered by one amplifier channel operating into a two ohm load. In triamp mode the LF and MF sections of up to eight enclosures can be powered by a single two channel amplifier.

The high-frequency section consists of a 1.4" exit, 3" 16 ohm, neodymium compression driver, mounted on a proprietary multiple aperture diffraction slot waveguide. This patented device produces the ideal linear source needed for good line array performance, and facilitates the enclosure’s exceptionally wide horizontal coverage.

The WL2102 features lightweight, highly weather resistant cored composite construction resulting in a net weight of just 70 lbs per enclosure; less than half the weight of some conventional designs.

The enclosure of the WL2102-w (pictured) is constructed of industry standard birch plywood resulting in a slight increase in weight; 83 lbs/37.7 kg vs. 70 lbs/31.8 kg for the WL2102, 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. The mechanical design allows composite and plywood enclosures to be arrayed together.

Wideline features a unique 3-point suspension system allowing construction of arrays of up to 24 enclosures (5:1 design factor). A 12 enclosure hang will maintain a 10:1 design factor which may be dictated by local regulations and practices. Vertical splay angles between adjacent enclosures are adjustable in one degree increments from zero to ten degrees. All hardware required to construct an array is permanently attached to the enclosure; there are no loose parts to misplace.

Two array frame models offer the user the flexibility to choose the right tool for the job. The AF2102, the larger of the two, can accommodate array sizes up 12 enclosures while maintaining a design factor of 10:1. The smaller AF2102-s does triple-duty; accommodating suspended arrays of up to six enclosures with a 10:1 design factor, acting as a base for ground-stacked arrays of up to six enclosures and as an attachment allowing WideLines to be stacked atop QSC 215PCM and 215SB subwoofers.

Signal Processing Requirements

Like most line-array systems available today, QSC WideLine and ILA line-arrays require carefully optimized signal processing in order to perform as intended. QSC has developed processing settings for these loudspeaker systems using our SC28, BASIS and Q-Sys digital processing devices. Arriving at these settings requires skilled engineers, sophisticated measurement equipment and repeated listening in various environments.

It is not possible to simply take the parameters from a QSC processor, transfer them to another processor and get the same results. Other processor manufacturers use different algorithms and design techniques that will produce a different transfer function even if the settings are substantially the same. As a result, QSC is unable to provide settings or tuning support for our line array systems when used with any processors other than those specified by QSC.

WL218-sw WideLine Subwoofer

 The WL218-sw is a premium, high-performance, dual 18" subwoofer designed for suspended or ground stacked use in the most demanding touring or installed concert applications. With an impressive combination of punch, low-frequency extension and accuracy, the WL218-sw is an ideal companion for QSC's acclaimed WideLine as well as other professional sound reinforcement systems.

Sound system designers and operators are increasingly turning to subwoofer systems that are flown with the main array for a more seamless acoustical transition from the bass to the low-mid region. With a simple, three-point suspension design that is essentially a scaled up version of the QSC WideLine system, the WL218-sw fulfills the requirement while also delivering powerful and stunningly accurate low frequency output.

Suspension of the array requires one AF218-sw for each subwoofer array. The AF218-sw is a simple, heavy-duty array frame constructed of welded, aviation-grade 6061-T6 aluminum and intended for suspension of up to eight WL218-sw subwoofers with a 10:1 design factor. For ground-supported applications, the subwoofers may be stacked using the interlocking feet and recess features machined into the enclosure's end caps.

The 18" woofers incorporate a double layer spider and triple roll surround for extended and controlled excursion at extreme power. The 4" voice coil is wound on a fiberglass former to prevent deformation at high operating temperatures and is extensively vented to reduce power compression. An aluminum demodulating ring is employed for low distortion.

The extremely musical yet powerful performance of the subwoofer is the result of carefully balancing the transducer selection, cabinet volume and port tuning. The resulting system offers plenty of "punch" while maintaining ample extension so the musically important and satisfying fundamentals are solidly and accurately reproduced.

The enclosure of the WL218-sw is constructed of premium quality birch plywood finished in an environmentally friendly, waterborne, polymer finish that stands up to life on the road while also being field repairable. Extensive internal bracing is employed to eliminate acoustic losses due to panel resonance. Further contributions to cabinet rigidity come from vent walls constructed of the same plywood as the enclosure. Each woofer is protected by a heavy-duty, 14 gauge, powder coated steel grille and housed in its own, separate chamber to prevent failure of one driver from causing damage to the other.

Despite the extremely large amount of air moving in the ports, careful attention to detail has resulted in a system that is free of port distortion "chuffing". Ample port area allows massive amounts of air to move freely with minimal turbulence and 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 dolly has rugged, 3.5", ball bearing casters and an elegantly easy-to-use, snap on mechanism for attachment to the enclosure.
