In Reply to: Inductor is 3.3 mh with a low DCR of 0.185 ? posted by Ed Hsu on February 23, 2000 at 04:19:15:
that's a tad large for a 1.2kHz XO on a 4ohm driver. A 1st-order would mean a 0.53mH. A 2nd-order,Linkwitz-Riley would be ... 1.06mH & 16.6uF
Bessel would be ........... 0.92mH & 19.0uF
Butterworth would be ...... 0.75mH & 23.4uF
Bessel would be ........... 0.53mH & 33.2uFdid you measure the choke?
