I have two blown MA Audio MA83XE's (8 in. subs) and i completely took them apart finding out the the voice coil of course, was melted. I measured the diameter of the voice coil from gap to gap and its 1.5 inches, is it possible to make use of these old motors/basket? or are they completely done for? If anyone has good advice on what to do with them, your advice is much appreciated. Thanks

Have any doors in need of a good door stop?

You could probably find someone to recone them into something functional. But most of the "typical" places you'll be sent for a recone are probably not going to stock a 1.5" coil or the spiders to fit such a small coil. In the event you found one, I have a doubt the cost to recone them will be worth it. Not sure what basket those use, but that could turn out to be another issue.

Find something fun to do with them. I've built a clock and a lamp out of old speaker parts for shits and giggles.

But I wouldn't waste the money to try to repair them.

there are no shops or online part stores that would sell the re-cone kit? or what about just finding any basket+cone kit that fit the 1.5 in. coil and mounted on the motor?

IMO for the cost of the recone, if you found one, plus the cost of a basket, if you need one, plus the cost of shipping.......you could probably spend not much more money (probably less money) and purchase a new or used driver of substantially better performance than you'll ever get out of that MA motor.

You have to remember you can't just throw random parts together "because they fit" and end up with something that not only functions but functions well. Chances are you won't find an original recone for that driver. None of the major internet reconers (Fi, PSI, etc) are going to stock 1.5" coils, or the parts to fit a 1.5" coil. So they would have to get one custom wound, which they either 1) aren't going to do, or 2) isn't going to be worth it cost wise. Plus the issue of finding cones/spiders/etc to handle such a coil. Which means you are going to get a cobbled together parts driver that is more difficult to predict resulting performance on.

Why? It's not worth it. That driver fully functioning in original form wasn't a good driver. That driver, if you could even get it reconed, isn't going to be a good driver. You're wasting effort. Throw them in the trash & move on to something better. I can't make it any more clear.
