using the mystery driver(s) for my new slim speakers, i have come up with this

C = 337.4 F
L = 6.209 mH
R = .653 ohms

Note: R should be adjusted by sub-
tracting from it the DCR of the coil.

now the problem is, that seems like a lotta microfarads. is this correct? please only people who know what they are talking about. i am also looking on vikash's site and he doesn't use caps anywhere NEAR that for his. his are at 3.3 uf, much unlike mine. his resistors are 6.6 ohms and his inductors are nearly the same. it seems as though the numerical values are the same, but the decimals are off. what's up?

fs is 110
qms is 6.57
qes is .65
dcr is 6.6
