Ordering the parts for a set of 4Pi Premium series. I want to experiment with active crossovers and I've dug up a couple DIY designs that I'd like to build. Both will allow me to pick crossover points, use 4th Order designs and do some level matching. W...

Active crossovers
Compensation components R1, R2 and C1 don't work independently. Every component in the passive crossover (including the drivers themselves) interact to produce the overall response curve. When implementing an active crossover, it is best to provide tweet...
