Alright, got in touch with Kevin over at DIY Cable and he said he would happily replace the driver if i ship it to him and cover all return costs. This is awesome news and more then I could have hoped for as it is somewhat questionable as a warranty item. Only thing is, I live on the opposite coast in Canada so this is no doubt going to be expensive so i figured I'd look to you guys for some other options.
I'd like to attempt a repair myself as it seems rather intuitive. Here are some pictures, I intend to remove the dust cap with a utility knife and hopefully be able to access the tinsel lead/voice coil soldering point and replace all four leads with slightly longer tinsel. Upon replacing leads i would affix a 5" dust cap in pace of the current 4".
This is just a best guess as to my options, any suggestions otherwise would be great as I thoroughly enjoy listening to this sub and will be careful to keep it under wraps after repair.
Thanks for all the help to date!
