An upgraded subwoofer, the WL118-sw is a single 18 version of the popular GP218-sw touring subwoofer that offers offers an impressive combination of punch and low-frequency extension. The addition of the SC28 System Controller with its simple-to-use presets, has greatly improved the ease of deployment of the system and the sound quality markedly enhanced.

Features:

• Single 18 subwoofer in a bass-reflex enclosure
• 850 watt continuous power capacity
• Frequency range down to 29 Hz
• May be suspended at the top, or behind the WL2082-i array
• Available in black or white to harmonize with venue décor

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.

Accessible
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. 

Affordable
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.

Accurate
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.
