Can anyone tell me or direct me to documents highlighting differences between the different Altec Lansing 417 speaker versions ?
I tried finding the info in the Stickies but could not get any info.
Particular questions:
1) What is the difference between
417 16Ohm (no -8X) designation
417-8a
417-8b
417-8c
2) Which years were each made
3) How do I know if a 417 is EV made or Pre EV era ?
I would guess it is the rounded basket shoulders for pre ev and the sharp edged basket shoulders for EV ?
Am I right ?
