ILA Series

ILA is a line array system designed specifically for installation in a variety of venues including houses of worship, sports facilities, clubs and other entertainment venues. 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.

Most line array systems currently available are designed for touring applications, which require 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.


Each Installation Line Array element uses a pair of high-power, neodymium magnet, 8-inch 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-inch (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. The system may be used in bi-amplified or tri-amplified mode. In general, the tri-amplified mode will produce the best performance and, for arrays larger than four boxes, will not increase the total cost of system amplification. 

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 is IP33 rated, and may be used in limited 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.

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.

The subwoofer for ILA System v2 is the WL118-sw, a single 18-inch version of the popular WideLine-10 touring, dual 18-inch subwoofer and offers an impressive combination of punch and low-frequency extension. 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.

Modern line arrays rely on digital signal processing to perform their best.

Intrinsic Correction is far more than just signal processing. It is also a process that begins by taking extensive laboratory measurements of the loudspeaker and then spatially averaging those measurements using a proprietary algorithm. Once the spatially averaged response of the loudspeaker is determined, a combination of IIR and FIR filters is applied to adjust the time, frequency and amplitude response to a maximally flat band-pass target. 

The result is that signal processing adjustment is no longer a task requiring complicated test gear, prolonged measurements and golden-eared experts. These presets are available via Q-SYS.
