1st off - one of these is more efficient/plays louder than the other. Alnico discharging? I don't know the issue.
I don't know what model speaker they are from. Stamped frame assures mid end (as in not high end) range.

The cones and surrounds were new when I bought them for $90. Since they aren't "spl compatible" am asking $35 for both plus shipping from 95521.
