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

[Kon Zissis]

Hi everyone.
Does anyone know what the actual individual power handling ratings in
watts RMS are for each of the stock 15 inch and the 12 inch speakers
inside the PR-40 cabinet?

My PR-40 tone cabinet was matched with my 1962 C3 when I bought it.

The two black 15 inch bass speakers with alnico magnets were built by
Rola ( code number 285...)  , and  the two black 12 inch speakers with
alnico magnets are Jensen P12Q  ( code numbers 220... ) .

Thank you in advance for a reply.
All the best.
