Hello i need a set of midrange and tweeter. Crossover for a nola viper speaker any have any schematics or info on who can make them nola said they dont have anymore
may want to give Danny at GR research an email they do custom crossovers, etc. and could build one for your speakers. mind you you will have to send them a speaker for testing. 
I'm trying to understand.  You need a replacement tweeter / midrange, or are you missing a crossover?
