Most speaker uses wirewound resistor in crossover. Is there any reason for this apart from their high power rating? Would it be technically superior if I replace them with a bunch parallel metal film or metal oxide resistor? With the later I don't even need to parallel them since they come in high enough power rating.
I read that metal oxide resistors are preferable for tweeter application for their low inductance. On my speaker crossover I have a bunch of inductors in it. So I guess, when inductance is not an issue wirewound resistors are superior for their lower noise?
I haven't traced the PCB, can I safely say that the wirewound resistor (4.7 kohms, 5W) Or is it even wirewound (it is encased in white ceramic type material)? Does wirewound come in such high resistance value? that is in there and the bunch of inductors are for the woofer?
