Hey guys, not sure where in the forum (if anywhere) I should post this.
Basically, bought a bass guitar amp dirt cheap because one day it worked, next day it quit they said. Had hoped a simple issue like a bad solder joint, but instead looks like the coil started to unravel inside and the wire eventually broke.
Managed to get the old coil out and the cone/spider are undamaged and still in place. Coil a bit deformed. I was able to get some measurements and about to make a paper mockup to ensure I have the correct diameter. Problem I'm having though is finding a match.
Seems like a 36mm or 36.5mm coil. 34mm tall. Where I am really having trouble is with the wire coil width itself. Everything online is between 12-14mm, and this thing is only 7mm.
So... first obvious question is, what would happen with a new coil if the winding width is 5-7mm too wide?
Does anyone know where a new one can be made without sending it in?
Should I attempt to make one? 32AWG wire isn't too pricey for a roll, though the roll is much larger than I need. Aluminum wise, I was thinking of a Coke can.
Thing is, it's a stock speaker from a Fender Rumble 75... it's generic made in China and not great to bein with. If I can fix it for $25, great... otherwise I'd rather just wait for a used 12" bass speaker to pop up for sale. That said, it's currently dead so, may as well learn and have fun with it. 😀

Cut out strips of paper that I drew on Illustrator for accuracy and made some sleeves with them and the 1.5" slid on not too snug not too loose. Not sure if I need a bit bigger or not... how much space should be on the inside?
