Huh? Neo, I must have been smoking some very bad crap for far too long but could you recheck the LP spec for the original MMG?
Mine is the old design and came with the same 2.2mH coil as the newer ones. The only difference was the 2nd order caps (25uF). So, the x point would nominally be the same but with a faster slope.
An odd thing about the older tweeter is probably not widely known. The old tweeters in mine are 2.6 ohms (measured). The new tweeter is "probably" 3.5 ohms (extrapolated, not measured). With the caps that came with them, it would seem that:
- Old MMGs tweeter with 24uf@2.6ohm = 2550hz
- New MMGs tweeter with 12uF@3.5ohm = 3790hz
That 2.6ohm in mine caused me quite some anxiety when I tried Tazmon's capless HP mod and adjusted it for "flat" rsponse, years ago.
