hi,
I have a pair of N2600 crossovers, and was wondering if I was correct in assuming that the post driver connections numbers are:

1 = Woofer positive
2 = Woofer negative
3 = 075 negative
4 = 075 positive

Like the N1200 posts?

Also, tweeters don't stay at the same volume. I'm guessing the LPads need cleaning. But I don't see how to open the LPads.

I can also see the change in volume on an ohm-meter(connecting to tweeter posts).

Thank you,
Darrell
