I understand that if you have a speaker with a tweeter driver on top and two same sized woofers below it that many crossover designers will roll off the mids from the bottom woofer. Apparently there are some lobing issues or some sort of destructive interaction from leaving both woofers with significant program material in the mids. I currently have some speakers I'm trying to decide whether to modify (Klipsch KG 5.5) that have this configuration but the woofers are both fed the same signal with a crossover to them below 1.5 KHz. Is this issue something that some designs don't have much problem with for some reason? I've been considering upgrading to one of the Crites crossovers, but it seems silly to invest more in a possibly flawed design. I don't have the resources to design a better crossover - is there anyone out there who designs new crossovers for vintage speakers at reasonable prices?
