So you are an extreme slope fan? You have the 24db slopes on yours? Are the Universal ones capable of the 24 db slope, or do they just do 6,12, and 18 db slopes? I have tried to research Al's stuff, but it's just a loittle far out there for my brain.Can't quite wrap my head around some of his stuff., I know they sound great, I just can't grasp some of the theory...I can build crossovers from a schemo, but I really am just following the plan....wish I were smart enough to design them, and do measurements and such. I have all the software, but again....it's a little too far out ther for me, and I have no mentor close by who could help me.. If I did, I think I coulld get it..
