With both my high an low drivers being 8 ohm and the crossover point at 3500Hz, the calculators for 2nd order butterworth tell me:
L1 = L2 = 0.51mH
C1 = C2 = 4.02uF
I can wind a coil no problem, but that cap. :sad: I could use a 3.3 and a 680nf to get close but is that close enough? That requires fitting 2 caps on the board and metalised PP is expencive.
I could get the correct value http://uk.farnell.com/jsp/endecaSearch/partDetail.jsp?SKU=1190553 Which is metalised PP but meant for motors! Does it matter?
Should I change the x/o frequency to 3000hz to give me an easier value?
This must be a comon problem but I can't find the answer. What is the workaround?
