Well, I have been searching long enough, now it is time to ask the obvious.
What exactly was the relationship between Altec, Altec Lansing, and JBL?
I have some early 417 drivers marked Altec, but later ones were Altec Lansing, then Liang Altec or something.
Why was the Lansing name associated with Altec?
appologies if this was either too stupid or too obvious,
