I could keep going but I don't have that much time to waste on this little petty issue. I never said that you were wrong about the way you tune a system. It was the other way around. You are correct in saying JL doesn't say the way I tune, but here are other reputable companies' manuals and an article online on how to tune the amp. So before you go all high and mighty on how to tune a system, get your facts first. Maybe in the Portland Metro area of Oregon, we do things differently.
Tom - Good luck with your tuning. Let us all know how you did it and how you like the sound.
