[QUOTE="NDMstang65, post: 4745470, member: 544576"] Just curious, how many XBL^2 equipped woofers that you know of used a shortening ring? It's not the ability of putting a ring inside the gap that he's after, he's after the motor topology of xbl^2. I suppose we forgot how much stray flux is created we get when we do a 3-6 stack 8-10mm plates of varying ID's that are stamped out and glued together (every where there is a joint there is an air gap of glue between the plates which also causes stray flux all the way around the motor) instead of doing it the 'right' way instead of casting 1 piece? Wiggins will swear up and down it doesn't effect anything...model it, look at the graphs and bars and see where the flux is going. Every where there is an air gap there is a 'spit' in the model that looks like you sprayed windex out of a bottle away from the motor which is, stray flux. If you zoom back out and look at the motor from a side view the output isn't in a parabolic form, looks more like a wave then anything instead of a concentration in a parabola as it 'should' technically be. But if you want to throw screws at it from different angles I guess it'd serve a purpose...but it's significantly cheaper then casting/tooling a top plate...which simply goes down to a cost/benefit standpoint. Casting a notch out of a top plate from a design stand point is much better because it is one solid piece with no air gaps for flux to dance around randomly...you can still put a shortening ring in it if you feel you must because the notch in the gap would be there. However it is by far not as cheap as stacking thin top plates to get the desired gap height...
