Active divide crossover network or passive crossover network ?
What is active crossover network
Talking simply, it divides the signal from resource as CD, AUX into many signals which is decided by user in a range of frequency. For example low range is under 200Hz, mid low is from 200Hz to 2KHz vv..vv Due to the purpose of user, the signal will be divided into 2 ways, 3 ways or more...
The advange of active crossover network
Because the signal is very small so you dont need big parts and it is easier to find a good parts than passive crossover network. The signals are divided and user can easily choose which amp will handle a range of frequency and easy to boost up any range of frequency matching his favourite.
As the signal was divided from very low level, so the signal lost is very small and it is easier to set slobe for cut off frequency than passive crossover network.
The disadvantage of active crossover network
User needs many amps for his system and total cost will be more expensive
Set up music system is very difficult and in some cases it need professional device to make the sound correct.
You shoud divide your systems using max 3 amplifiers or not it will become too complex to handle.
The advantage of passive crossover network
Schematic is simple, easily to maintenance or upgrade. The is no need voltage so every thing is very simple.
You can use multi amplifier that one amp for one channel or one amplfier drive all drivers. This thing, you can not do with active crossover network.
The disadvantage of passive crossover network
It need big parts because it divide the signal from amplifier which has high power. You can not use CR filter because the resistor will make signal lost much. You have to replace resistor with coil which make the price of crossover become more expesive. The volume in crossover needs special ones that much bigger than volume using in active crossover network. Normally you need 50-60W volume, in crossover network, only 1/2W of volume is need. In some case to lower signal loss, you have to use transformer attenuator which cost much more than a normal volume. With passive crossover network, you can choose use one amp or multi-amplifier flexiblely but in reserve, you have to pay more money for parts using in network.
Conclusion:
Both active or passive network has disadvantage and advantage points, both needs much of budget for making a good system. Which is better belong to customer need and budget. If you just want to use one amp for all driver in system, then passive crossover network is the best. If you want to touch to the sound of overall system and have skill enough to setup a well balanced system, then active crossover network maybe a better choice,
