Module PCB LP-L3/2W (Large) up to 18 dB The requirements for a passive crossover for loudspeakers are many and varied. They are different for a 2-way bookshelf speaker than for a 3-way speaker. What all crossovers have in common is that they consist of combinations of low-pass and high-pass filters and voltage dividers. With the IT. PCB system, a large number of crossovers can be constructed with just 11 PCBs. The circuit boards are available in three sizes to accommodate both small and large load capacities (component sizes): L/M/S basis for the crossover of each combination is a circuit board that allows the construction of a low-pass and a high-pass filter with voltage divider. 2-way base plate (small): (low pass 12 dB / high pass 12 or 18 dB ) 2-way base plate (medium / large): (low pass 12 dB / high pass 12 or 18 dB ) 2-way loudspeaker If a crossover for a 2-way loudspeaker is to be constructed, one of the above circuit boards is sufficient. 2 1/2-way speakers If a 2-way speaker combination is supplemented with an additional speaker in the low frequency range, this is referred to as a 2 1/2-way combination. In addition to a 2-way base plate, you will need a low-pass PCB, which is again available in three sizes: Low-pass PCB (small / medium / large): (low-pass 12 dB) 3-way speaker As with the 2 1/2-way combination, you will need a low-pass PCB for the crossover section of the woofer. The midrange driver is equipped with high and low pass, so that in addition to the 2-way base plate you need a high pass PCB, which is also available in three sizes: High pass PCB (small / medium / large) : (high-pass 12 dB) RLC equalization Sometimes it is necessary to use corrective elements to influence the sound pressure or impedance curve in addition to the basic crossover circuit.
