is any pic or link or imp measurement available?

a delete of the bass resonanz and the advantage
for sound and amp, tube amp, would be found in the
1930īs if it would be done.

If it is Goodman Axiette you are asking for:
Axiettes of evil
Mine has higher Qes so I think you have to measure what ever driver you have to get exactly the right values but do not expect miracles. I rate Axiette as decent fullrange but not more than that.

While Bell Labs/W.E. measured everything they could including whole orchestras in Bell Labs' huge anechoic chamber, at this late date I imagine the information is either gone or buried in AT&T's or W.E.'s archives. The only information on the net I have seen is a hand drawn side view sketch of the layout from one of the documents except with Japanese? notations.

Maybe there is some information in the Bell Journals, but with my slow, poorly performing AT&T DSL service I do not have the time or patience to sift through it: Bell System Technical Journal, 1922-1983

Loud is Beautiful if it's Clean! As always though, the usual disclaimers apply to this post's contents.
