Tips & WarningsStereo 2- to 5-way systems are connected in the same manner with additional connection cables, amps, speakers and compatible crossovers.
Passive crossovers, those with non-changeable preset frequencies, are connected in the same manner.
Read the crossover user manual for proper settings, and the PA horn and woofer specification sheets for frequency ratings. Failure to do so will result in poor sound and possible damage to the horn and amplifier.
