Reconing a sundown SA 15...expertise needed

[cabnab89]

Hi I'm lost and unsure where to post this thread..

I'm reconing a black motor sa 15 with a std sundown drop in.

I've disassembled more like destructed the sub already,

going to paint the frame( why I seperated to begin with )

I broke the plastic spacer between the motor assembly & frame. Id Rather not buy a sundown spacer.

By changing the thickness of this spacer what happens exactly?

Measured with a mic it's .4000 closest tube sleeves i have laying around are .3750

Assuming wcs it's better to increase

What happens when spacer thickness decreases. Coil crash?

Thickness increases?

Better voice coil venting by using tube sleeves instead of spacers?

Any advice welcomed, thank for the help in advance

Assuming the spacer is stock and your recone is a drop-in kit you MUST replace it or keep the same space there. The coil must be properly aligned within the magnetic gap or the sub will not function properly. Correct spacing between the spider landing and the gap is critical.

If you have separate coil, spiders, and cone you can just center the coil and build it piece by piece, but I'm guessing you have a drop in style kit,, in which case you'll need to get the correct spacing for the woofer to function properly.
