I started to help out Drew Campbell, owner of Paramount Automation with a set of Bose 901 speakers.
There are 18 four inch woofer that need to be done. Once we started pulling the woofers out we had to make sure we colour coded the leads as there was no rhyme or reason to the colour that Bose used.
Shimming the voice coil had to be done with very fine paper as the gap has a small tolerance. We managed to get through a few woofers but this will be a time consuming project.
