[QUOTE="honkyg, post: 8597365, member: 606879"] it looks tc based, ive always thought, but the wind height on these things are three to three and a quarter inches, if memory serves me. excursion linearity differs from actual excursion, its how well the former/coil stays aligned within the gap tolerance on axis at full physical in/outward extension (within mechanical limits). single spider locations lend to being a pivot point to the coil opposite the surround/cone hinge point, susceptible to rock/rub and uneven saturation. triple, or even double spiders spaced that far apart negates the pivot point.
