I have a pair of Atomic APX motors. These motors are a few years old, I beleive the APX motor is a bit differant now. They are double stacked, not sure of the weight of the magnets, they have a 0.75" top plate, and have multiple pole vents, plus vents directly into the gap for extra cooling. They are in pretty good shape, I have had them for awhile so there are some marks and chips here and there but hey will still function no problem. The gap is really tight ad like I said this is for motors only, that way you can get a recone kit (from Atomic, or American Bass) and recone it to whatever size you want with whatever coils and spiders you want. If you want them to be 10" I can give you some baskets that I have, they are used and would need to be cleaned up but you can reuse them easily enough just takes some grinding off the old glue. The buyer must pay for shipping. I accept payment by money order only. Pictures are attatched, email me at newdeal_99@hotmail.com if interested.
