[HAM] Inductors and Caps needed for a Leslie Crossover

[David Anderson]

Hi Tim,

Madisound is a good source of speaker crossover components:

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.
