[HAM] What is the power handling rating of each of the 15 inch and 12 inch speakers in the PR-40 tone cabinet ?

[David Anderson]

Kon,

I can't help you with the Rolas, but I know the last letter in the  
Jensen part number denotes power handling:

I think more detailed information is out there, but I can't find it.  
Note that the reproduction Jensen speakers have higher power handling  
ratings than the originals!
