I'm hoping someone could lend me a helping hand....

I'm having difficulty finding a reliable passive crossover calculator for a 3-way system. Anyone know of any (other than the Xover Pro retail version) that could do this? I'm looking for a second-order crossover, to be more specific. If there is one that I could use that uses "off the shelf" parts, that would be even better!
Also, impedance compensation calculators would be useful.

I'm stumbling until I get one.  

Thanks!

Sintz,  Here are the mathmatical formulas to do it the hard way.

 If you told us what drivers you were using you would receive more input.
