Question
Hi I have a pair of vintage Technics 3way speakers now the specs are:
model#SB-K915
impedance-8 ohms
140watts MUSIC
92db@1w/1m
tweeter:10khz-20khz
midrange:3500hz-10khz
woofer:30hz-3500hz
So the midrange and tweeter finally blow so what is the True power RMS and SPL rating now for the woofer that still works?Thanks

Answer
First, there is no such thing as "RMS" power. It is a misnomer.  RMS is for voltage or current but not for power.

Woofer specs are those given above in your question.  But, so what?  Are you intending to use them as woofers?  No problem, go ahead and enjoy them.  They are good product.
