I have a 416 8b in a 12 cuft cabinet with a 808 8a driver mounted to a 400hz tractrix horn the tractrix horn is shorter than the 811 so i can line up the voice coils without the horn sticking out past the front of the cabinet. so if i go to a model 19 crossover can i keep the voice coils in line or will this effect the crossover? iam told the mod 19 crossover is time aligned and that changing the distance between voice coils will effect the crossover is this true? also looking for a place that will use calsod or leap to design my crossover i contacted madisound and was going to ship my drivers to them but my money and my request was turned down! i take it they dont like vintage drivers or they just want to sell crossovers for speakers they sell. anyway any advice on the crossovers would be great thank you.
