    Yeap they are the ferrite versions. Today i realize that both tweeters got same sound and less gain than my older ones. The old ones are a little sharper and brighter in sound. But they are also 1ohm less than the new ones!

    Looking at the diaphragms, it appears that even though it may appear that no one has opened it, in fact they have.

    So why is one quieter?

    Possibly, (and a very real possability at that), is that when reassembled, the tech/whomever did not secure/hold the phase plug steady on reassembly as they tightened the screw. This will then allow the diaphragm to twist a bit in its mount and this will reduce the volume.

    It could be that they will both sound about the same on reassembly, assuming you don't make the same mistake.

    BTDT!
