One example of how American professional audio technology has advanced in the design and application of mid-size line arrays is the QSC LA112, a 12-inch small line array sound reinforcement system.   This three-way passive line array system consists of a 1-inch compression tweeter, a 6.5-inch midrange driver, and a 12-inch high-efficiency Neodymium woofer. It has a directivity pattern of 10° x 90° (V x H) and a wide frequency response of 50 Hz to 18 kHz.   It has a professional-level line array performance and is an affordable system option for mid-sized shows and stationary installations thanks to its exquisitely constructed birch plywood enclosure and proprietary Waveguide horn technology.

With the built-in quick-connect flight case system and a range of configuration choices, sound professionals can rapidly build up line array systems with 4 to 16 units. Strong polyurea-coated housing and professional-grade rigging points are essential for QSC amplifiers to function well in a range of performance and installation settings. By delivering the highest quality and dependability of American line array technology to mid-size performances worldwide, the LA112 demonstrates that QSC is extremely skilled at creating tiny line arrays.
