Crescendo Mezzo power handling

[DylanBunch]

I have 2 sets of crescendo mezzos and I contacted crescendo about power handling asking if it was 150 per set or 150 per side ( meaning 75 per speaker) and they said 150 per channel. Where im confused is the back of the mid says mezzo 150 and the back of the tweet says mezzo 60. Is that the power rating per speaker or is it 75 per speaker or what? Pretty confused and i need to know because it will determine what amp(s) i used when i have all 4 sets.
