I don't have a link unfortunately, I can e-mail it to you though if you are interested in having a look? Thanks ~Andrew

For a parallel crossover, does anyone subtract the inductance of the woofer from the calculated value for the inductor?

Tom, series or parallel, no -- one does not do so

JE's T/S specs. have lots of errors. Acoustic output / watt input isn't really that useful as almost all amplifiers are voltage sources. Assuming the basic T/S specs for the CW2137 are correct, the particular woofer only has a voltage sensitivity of 87dB/2.83Vrms/1m. Like what the others have said, measure-measure-measure!

swin1, the mids will need a rumble filter or they'll be easily damaged by bassy software [not to mention they'll also sound bad].

Cheers!
