Sonusman is correct again, you can change crossover points on a passive crossover. Some passive crossovers come with different terminals to allow you to select different crossover points. You can remove the crossovers from your speakers and replace with a different crossover with crossover points more to your liking but your speakers were probably designed properly with the proper crossovers. You could even remove your crossovers and replace individual components on them, caps, coils, etc to get different crossover points but you really dont want to do any of the above. I just blew another crossover in my tannoys, #2,sonusman, how would I fuse them to prevent melting them for a third time. I was thinking of buying a less powerful monitor amp but cant afford it right now. I melted the them last time and my daughter got em this time.
