Ford Galaxie

So I've been looking at the crossover values of the K-52 mid for KLF-20 and 30. High passes for KLF-20 are 750 and for KLF-30 is 825. I have a pair of each. I also have the Crites KLF-20's crossovers with the 3636 autotransformer. also. I'm looking at lowering the crossover points of the K-52 to 625hz. Looking at the crossover values in this crossovers, I cannot make any of the values in the KLF-20 and 30 compute with the various online crossover calculators, so I'm at a loss as to how to find values to lower the K-52. Little background on this setup- I've been using a pair of KLF20 mids with a Goldwood horn and KLF-10 tweeters in cabinet that has 2 Cerwin Vega 15's for the past 20 years. I've had the CVs lowpassed with a single .51mh choke and it works well enough however I was thinking about bringing the K-52 down a little lower.

Looking for complete pair of KLF-K100's (horn lens and tweeters) for a KLF-10.

Need to replace a busted horn for a KLF-30. Looking for a K703 horn .. I have Paypal and have been around on Ebay for 20 years.. R/ Michael
