I really doubt you know what's going to be better for the JL motor than JL does. After all, who spent millions on R&D? You or JL? Just saying, you're pretty much ruining resale value on it as well. It's an SQ subwoofer, good at sounding good. It's not some fart machine that you cobble together using bastard parts to hit 150+dB where it doesn't matter if it sounds good or not.
