The Genelec 1033A is designed for neutral audio reproduction at moderate SPL in medium size control rooms. The integrated system consists of two 173 litres (6.1 cu.ft.) speaker enclosures and 19" rack mounted electronics system consisting of crossovers, three dual channel power amplifiers and a dual channel Audio Processing Unit. The system is designed for flush mounting in the control room wall, but it can also be used as a free standing speaker with the use of the built-in radiation space control (bass tilt).
