Genelec 8040A and 8050A Monitoring Systems System Crossover Mounting considerations The GENELEC 8040A and 8050A are The active crossover network consists of two Align the loudspeakers correctly two way active monitoring loudspeakers parallel bandpass filters. The crossover fre- Always place the loudspeakers so that designed to produce high SPL output, low quency is 3.0 kHz on the 8040A and 1.8 kHz their acoustic axes (see figure 2) are aimed coloration and broad bandwidth in a small on the 805
