The system is based on a principle Qube calls 'the Isophasic Plane Wave generator', which employs a true acoustic lens in the horn section, loaded with the two 1" HF high-compression neodymium drivers, resulting in a line-shaped source evenly distributed within the cabinet as well as with the line array. Qube says this allows high power and precise line array performance to be generated from a column (minimum six speakers) of bi-amped cabinets just 60cm wide. This makes the QSA-210 ideal for medium-sized touring applications as well as installations in theatres and similar venues.
The cabinets are designed for quick setting-up and the included two-point flying hardware allows two different settings (0° and 5°) for straight line array as well as curved clustering. Technical specifications include horizontal dispersion of 150°, and vertical dispersion of 5°. Sensitivity is 103dB (1W/1m), maximum SPL is 127.7dB. Dimensions of each cabinet are 60.5 x 29.5 x 40.5 cm, and the weight is 32kg.
