LOL. Anyways, speaker manufactures are always trying to build a sub with high power handling and good transient response and the voice coil windings are a constant hassle for them, if they put lots of layers they'll have lots of power handling but a heavy slow moving voice coil as well, so they try to get the best of both worlds by finding a happy medium.
Lots of layers on the voice coil isn't always that wonderful of a thing, instead look for a sub with a **** load of Xmax and a low power rating, those will give good, hard hitting bass while still miantaining a good transient response(I consider 12mm of one way Xmax to be the minimum for high excursion woofers)
