i have a 12'' Mtx 7500 but i bought it blown stripped it down for rebuild and the magnet was shifted. i have adhd so i start way to many projects at once. i have one that i just have to reglue the basket base plate centered (top of the magnet pole plate) and throw the thing together. has a new cone and much better surround but i do have the old one i could use if you want it. the dust cap was dented but it doesn't look that bad maybe when its glued down it will straighten out... MTX is over priced and anything under 7500 series is mostly garbage. i could hurry the build up and send you pics of it if you looking for just one? also have to repaint the basket. probably going black
