Hello everybody, I'm building the kappa perfect subwoofer and I have a question about the crossover to use, a friend of mine is selling me a Peavey crossover Peavey crossover http://www.peavey.com/media/pdf/manuals/xd34.pdf, does this crossover will be ok for what I need or with the FMOD High Pass Crossover 20hz (subsonic) will suffice? http://store.hlabs.com/pk4/store.pl?section=9 :confused: Tom
