:helloman: Mike !
Don't worry!
I found last week a pair of Seas H107 1" dome tweeter to replace others (1 original, 1 approaching..).
After test, one was working smoother than the other, tweeter dead

, coil stuck between magnet (core has moved)...
Results: still looking for another H107, or H098 pair.
The only great things is that with only one tweeter working, Seas one is soooo much better than T2.
