[QUOTE="hispls, post: 7705830, member: 614752"] Mostly lowers Fs. Adding a kilogram of mass to the cone brings fs to mid 20hz, but that's not really a solution I said 18. Same motor with different coil, cone, and softer suspension Re 2.83 [Ohms] Fs 29.61 [Hz] Zm 43.69 [Ohms] BL 27.50 [N/A] Qms 3.887 Qes 0.269 Qts 0.252 Vas 176.400 [liters] L10k 2.38 [mH] n0 1.62 [%] dBSPL 94.20 [1W/1m] Ms 386.90 [grams] Cms 0.07 [mm/N] These went pretty well, but unforunately I cannot get those spiders any more, the cones don't hang with 6K, and the impedence of those coils doesn't add up to anything my amp likes.
