Are you unhappy with letting the SF's roll off naturally and just using the crossover that is in the F110?
If you are looking for a cheaper option than the JL crossover, look for a used Velodyne SMS-1. They are discontinued but even new they were only $400 or so. It will do what you're trying to do and it has a great spectrum analyzer to help dial everything in.
