hi, i am going to build a custom jbl speaker. mid 2441 16 ohm with smith horn, low le15a 16 ohm and also 075 8ohm. i know lx5 and n7000 crossover should be used, but the price........... Any aftermarket crossover can be used? Perhaps anybody has the lx5 and n7000 crossover diagram or any custom crossover diagram i can build by myself? Thanks!!!!!!!!!!!
