hello friends...
I have been trying to study about the passive crossovers for few days and one thing I noticed is that the matching the specifications of an inductor to the speakers make the passive crossover difficult to built. I was under the assumption that an inductor is is used for much higher frequency band (100kHz or above) and I don't know whether its true or not. Usually for the audio amplifier at the audio output usually a capacitor with speaker impedance forms the cutoff frequency right??. So what is the use of a specific passive crossover with specific inductor?? So could anyone help me out??

 

Hello,

Have a look at the following article:

Inductors can be used down to very low frequencies. For instance, mains transformers at 50/60Hz. It all depends on the inductance and using core materials suitable for the intended frequency.

 

Thank you friends for the help
