I have now finished building 2 different passive crossover filters for my MTM diy.
They have slightly different curves, number of components & values.
But i wonder about Power dissipation over the komponents in the passive filter, especially over the resistors.
At xover Nr 1: VituixCAD shows that one of the resistors get 119 watt at 33 volt RMS, and the other 2 resistors get 38 and 25 watts. ( with HPF Butterworth at 340 hz )
And at xover Nr 2: VituixCAD shows that the resistors only get 10 watt. ( with HPF Butterworth at 340 hz )
Im using the MTM after active filter at 340 hz, and have passive filter in MTM crossed at 2K
My question:
Is one of the xovers "better" for components, amp, drivers ?
Does the resistors really get so much power ?
Today i will sitt and listening on the 2 different xovers, and I don't know which one I will choose in the end, but want to know if anyone sees any direct problems with any of my filters?
Best regards John
