8000 Series Operating Manual Genelec 8040A and 8050A Monitoring Systems
Genelec 8040A and 8050A Monitoring Systems System Crossover Mounting considerations The GENELEC 8040A and 8050A are two way active monitoring loudspeakers designed to produce high SPL output, low coloration and broad bandwidth in a small enclosure size. They are suitable for a wide variety of tasks, such as near field monitoring, mobile vans, broadcast and TV control rooms, surround sound systems and home studios.
Figure 2. Location of the acoustic axis Cable RCA (Source) Figure 1. Amplifier panel layout of the 8040A Minimum clearances Sufficient cooling for the amplifier and functioning of the reflex port must be ensured if the loudspeaker is installed in a restricted space such as a cabinet, or integrated into a wall structure. The surroundings of the loudspeaker must always be open to the listening room with a minimum clearance of 5 centimeters (2") behind, above and on both sides of the loudspeaker.
