I just redid the crossovers in my speakers. I used the exact same values but upgraded all the components and added bypass caps to the mids and highs. I also verified the resistances on the inductors as this can change the performance of the system.
My new components were so large that I decided not to shoehorn them all inside and moved my crossovers outside the speakers.
I spent over $3000. You can see photos of the completed crossover in my virtual system.
The improvement was huge and at the same time subtle. Very refined.
