Op-amps are extremely easy to work with. You can design an active crossover with them using the design tool below. Choose a nice Burr-Brown chip for best results. I'm using 627 and 404 chips in a sub crossover I'm working on right now, and there are other op-amps that work very well too. The 627 is good when used in circuits with unity or low gain, like active crossovers.For the four π crossover, I've found best results with 3rd-order slopes ( 3 poles) on both the woofer and tweeter. The LP transfer function for the woofer has a little bit lower knee frequency, about 1.3kHz. The tweeter is a little higher. I suggest using a potentiometer in both circuits to dial it in. You'll also need to provide CD equalization with an RC network.
