After months of toruble free operatoin, my Boston sub has broken its connection to the voice coil again. This time, it doesn't look like I can just resolder to the leads under the dust cap.
How are VC's constructed? Is the tinsel lead actually part of it, or just soldered in? I want to stick the speaker wire directly up to the VC, but don't want to screw anything up. I am sure I can find some way to make it work otherwise, but want to do this as a longer term solution to this temporary solution sub.
P.S. I would love to replace this sub, but can't afford to, hence the numerous repairs.

Tough call Shoot... when the VC lead separates from the tinsel lead, we can sometimes resolder it and good to go. However, if the VC wire breaks, we can sometimes remove the dust cap, release a turn of VC wire and try to resolder it again. (This is often a very delicate process)
VC wires are often epoxied to the the coil former and the wire is also coated with a very thin insulation layer. To solder the new connection, we have to remove the insulation on the VC wire to make it solderable again. (About 1 inch is needed to work properly)
Good luck,
Swez

It wasn't as bad as I thought. Turns out that I am blind, and the lead severed on the back side of the sub, so I pulled off the cap, pulled a lot of wire through, and soldered the hell out of it.
I will see how well it works when I put the dust cap back on today. Any advice for a good adhesive for the dustcap? I have been using Krazy Glue, and this time it was just stupid hard to pull off. I would like to try something new.
