I had a pair of three-way crossovers made a number of years ago. Unfortunately, I don't remember what the crossover points were on them. Can someone who is much more crossover-savvy offer some advice on how to determine the xover points? A posted picture? An attempt at a description? A layman's circuit drawing?

I would like to use the crossovers for a DIY project but, of course, I can't know which components to use unless I know the crossover points.

Help!
