illistillusion

Purchased an fi btl sub off craigslist. long story short, the previous guy who owned it did a VERY bad recone job and the tinsel leads that go into the spider were shot and the wire that goes into the cone is too short and when the sub excursions, it simply rips out of the tinsel. I'm going to order a new recone kit but i cant figure out if theres a difference with the btl/n2/n3 and which model this is.. I deleted the guys number because I was so pissed at him that he would sell me something fked up. if anyone can help me figure out what it is or if theres anyway to tell please let me know asap!
