Available in black or white, the WL2082-i enclosure is made of high impact polystyrene with extensive internal ribs to eliminate acoustic losses due to sidewall flex. The Installation Line Array may be used in outdoor applications where the system is not directly exposed to the elements. The enclosure material is formulated with UV inhibitors, the grille is made of aluminum and the woofer cones are weather resistant.


  • Installation-optimized design brings affordable and uncompromised line array performance to a broader range of venues
  • Compact and attractive appearance, available in black and white, harmonizes with any installation environment
  • Wide 140° horizontal coverage
  • Economical and easy-to-install suspension system with ample array adjustability

Line array systems have become the primary loudspeaker configuration for tour sound and many large installations. With the advent of the ILA Installation Line Array System, QSC offers a professional system at breakthrough pricing making line array performance accessible to a far broader range of house of worship and performance venues.

Accessible, affordable, accurate.
ILA is a line array system designed specifically for installation. ILA System v2 is a complete system consisting of line array, subwoofer, processing, amplification and suspension accessories. The result is an accessible system with very high performance, moderate cost and ease of deployment.

An ILA system doesn't require set up by an expert user with sophisticated acoustical measurement equipment. The SC28 system controller offers simple preset recall processing. While it's simple to use, the SC28 offers audio quality so good that it's being used on major concert tours. To achieve this combination of simplicity and performance, QSC developed the proprietary Intrinsic Correction™ process.

Most line array systems currently available are designed for touring applications. Touring requires extreme ruggedization and expensive suspension hardware. As a result, overall system cost is driven beyond the means of many facilities that could benefit from line array performance. By focusing on installation applications, using a molded enclosure and simplifying the rigging design, QSC drove cost out of the ILA system while retaining the sound quality, coverage and power of high end touring line array systems.

Each Installation Line Array element uses a pair of high-power, neodymium magnet, 8" diameter low-frequency drivers. Both woofers produce low frequencies but only one covers the mid-range resulting in more uniform directivity in the crossover region. For high frequencies, a pair of 1.75" (voice coil diameter) neodymium compression drivers with titanium domes are mounted on a multiple aperture diffraction waveguide* that provides extremely wide coverage (140º). As a result, a WL2082-i system will rarely require additional side or center fill speakers and solid stereo imaging is preserved across the listening area.

Rigging for the ILA is simple, flexible and safe providing a 10:1 design factor with twelve WL2082-i systems in the array (see the owner’s manual for details before planning any array suspension). The array is assembled with the included bolts and the relative angle between adjacent boxes is adjustable in 1º increments for precise tailoring of vertical coverage. For those who prefer quick release pins to the included bolts, an optional kit of four quick release pins (QRP-KIT-1) is available.

ILA subs may be suspended at the top of an ILA array using the standard FP2082-i array frame. When trim height is limited, the ILA sub may be suspended behind the array using the available EB2082-i extension bar. For installations in which the subwoofers are ground stacked, the GP118-sw offers identical performance but omits the ILA-compatible suspension hardware.
