In Reply to: I believe the original MR/tweeter filter point is 2.7K, but... posted by jeffreybehr on July 29, 2015 at 16:01:20:
Straight as a string over its entire usable range, which definitely makes it easier to work with than a dome with varying impedance vs. frequency! If your original tweeter was a different impedance (6 Ohms nominal being the industry standard), your original highpass filter will be mistracking, throwing off both the corner frequency and the Q of the slope. Assuming your original mid-to high xo had both drivers down -6dB at 2.7kHz, and you haven't altered the lowpass section on the mid, a complementary third order highpass would be 8.2uF series/0.15mH shunt/25.5uF series, followed by an appropriate amount of L-padding which retains the 4 Ohm impedance.
Hey, since you've long ago voided the warranty on those speakers (heh heh), you might as well keep tinkering! Because nothing is EVER "perfect," and Goldilocks is NEVER completely satisfied!
