[QUOTE="req, post: 802618, member: 555713"] basically they use a huge fecking top plate (if youve seen a shocker sig, you know what i mean) to focus the magnetic energy on a small 'ring like' structure that sticks out between the pole piece and the magnet. this is called overhung, because the ring is at the top of the pole and the top-plate. wheras, "normal" motors just use the whole top-plate edge to form the magnetic gap, versus using a smaller surface area as the gap. lemme try and draw it cross-sectionally... [IMG]http://img10.exs.cx/img10/2313/motors8jc.gif[/IMG] now, im not exactally POSATIVE on how the overhung\underhung motors work. thats my IMPRESSION on how they do it. basically that little 'lip' on the top plate there, and the pole vent is where the magnetic field is strongest. and this is where XBL2 does its work. by using the same 'magnetic force' but centering it on the top plate, and 'overlapping' fields by cutting out rings in the pole and the top plate, it creates a stronger motor force and keeps the voicecoil\cone moving more linear with a longer stroke. its not "exactally" what the motors look like. but thats what my guess' are. anyone have cross sections of diferent motors?
