Living in hope@Analogous , Gotcha. I have always felt that vintage audio products makes sense only if you are able to bring it back to the original technical specs. meaning, it has to electrically and mechanically work as per the original specifications. Is that even possible with a speaker in such a condition ?
The drivers (including the surrounds seem ok) the cabinet is surprisingly good for something this old and it has a very enjoyable tone. A good start so far
