found this nice and old datasheet probably was a part of the Jensen brochure. and it’s great to see the exact output of the 50’s Jensen speakers. P12R was the stock speaker for tweed deluxe. and now I can see why it came with tweed deluxe. btw, P12R and P12Q share the same bell cover. and you cannot install P12N and P12P with the bell in tweed deluxe because of the size.
P12R = 12watt
P12N = 18watt
and, this thread in the same forum says
P12Q = 14watt
P12P = 16watt
