[QUOTE="sundownz, post: 5263150, member: 549523"] Just these things: 1) Adding 10mm to magnet stack (for more x-mech primarily, FEA shows very slight increase in motor strength) 2) Moving vent holes closer to the pole by 5mm (if the magnets are slightly off by even 1-2mm at current spacing they can block air flow, accounting for production tolerance) 3) Making the coil 5mm taller and increasing pole extension as well (since I have so much rearward x-mech I want to make it harder to jump the coil forward too) 4) Creating a plastic spacer ring under the basket (the pole was getting too close to the dust cap, it could potentially smack the cap with increased x-mech) - this is also why I used a bubble cap in the first place. Thanks for the comments [IMG]//content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif[/IMG] I am pretty excited about it - the cap will be exactly the same except with "Sundown Audio" on it.
