From Troels frequency graphs, can you give me an idea of what crossover for the LE14A? I do not know how to determine this with my limited knowledge of circuitry and lack of testing devices. Once designed, what item in this LF crossover would get modified to fine tune the proper roll off? Or, is it the mid crossover that gets modified with a fixed LF rolloff?
