Hi Tim,

Madisound is a good source of speaker crossover components:

or

For capacitors, you can find metalized polypropylenes on either the 
Parts Express or the Madisound website. Solen is a good brand.

I like using motor run capacitors in series with high frequency 
drivers. You can find them in 15uF values and parallel other 
capacitors to get the exact value you want. Motor run capacitors are 
usually a metalized polypropylene or paper in oil and are made to 
handle high currents.

Don't go cheap and try to use electrolytic capacitors in the 
crossover if you can avoid it.
