Homemade Super-Neo Woofer: THE CHEVELLE RESTORATION IS DONE, dampener recommendations??

You might have the magnets "upside down"

Neither phase nor magnet orientation would cause the sub to suck in.

I'd be willing to bet it's because of the weight of the cone / loose suspension. Sometimes it's a box design too

Try this: Flip the box upsideown so the sub is facing down and see if it pushes out this time

Lol alright, I'll try that out tomorrow.

and STEvil, the direction of the magnetic poles would not matter if I tried and switched the polarity anyway, instead of the normal North/South, it would be upside-down, but switching the polarity would "fix" it if that actually mattered. It would just mean the whole sub would be working backwards, but would still look just like a normal sub.

coil looks great man!

Man with a mind like that at your age you best be filling out those college papers like your dad said, would be a shame to see all that knowledge go to waste

But nothing is even due until July 15th, we don't graduate until thursday lol. But thats the way my family goes, on both sides. Grandpa and my dad are ridiculous engineers, academics is the only thing that matters to them....

But I appreciate the thought man lol, most people can't believe my lowest grade is in math.....but she makes homework worth like 40% of the stupid grade, and she literally assigns 4 hours of crazy HW a night, no matter what. Like were not all math-crazed asians out here, cut us some slack woman.

AIN'T NO SENIORS GOT NO TIME FOR 'DAT!

I was gonna crack an asian joke when you posted that formula for winding that coil but i restrained myself... lol

Couldn't you change coil impedance by size of coil wire?

Yes, and wire material

So I kinda got a little bit of coil practice in today, to try out aluminum flat wire before the magnets get here, and despite what I thought would be easier to wind, the aluminum proves to be a real pain to wind very evenly and correctly. Not sure why exactly, I thought the flatness would make it easier, but I guess since your winding up and downwards, having that edge is harder than a thin round wire that can just slip off any coils you over-wound on, whereas the edged aluminum can't and you have to unwind alot more.

I suggest using copper round wire for your first coils, then moving up to aluminum
