The Genelec 1034A was in production between 1989 and 1999.
The Genelec 1034A is designed for neutral audio reproduction at very high SPL in large control rooms. The integrated system consists of two 10.6 cubic foot speaker enclosures and a 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 built-in radiation space control (bass tilt).
