Hi Steven,OK ... you flipped, eh? :-))
So your metal plate is now at the back? I presume you also swapped L for R? ... bcoz the mid-panel needs to be next to the ribbon.
Yes, the mid-panel is wired in reverse polarity ... whereas the bass panel and the ribbon are in "correct" polarity.
Having reversed your bass/mid assemblies, you can now prove to yourself that you need to reverse the connections to the bass panel and the mid panel by attaching a 6v (or even a 1.5v) battery to the bass panel connectors. Have your wife/a friend watch to see whether the mylar is going back towards the metal or forwards towards the listener when you connect the battery (assuming you've got the '+' terminal of the battery connected to the '+' solder pad of the bass driver! :-)) ).
As neo has posted, if you want to get back to the original situation of bass driver in '+ve' polarity and mid range in '-ve' then you need to reverse all polarities at the amp.
I'd be interested in your comments about the difference in sound. :-))
Regards,
Andy
