Re: Scan-Speek 4" for 49 cents?
Don't break out the Elmer's just yet...

Blue is raw cone, Red is wood glue
There is a bit of peak suppression, but the bad news is that the only distortion that improved is 2nd order. All other distortions were slightly worse than stock at all frequencies. Sound quality is unpleasant.
FS dropped from 115 to 114 and Qes stayed the same. Interesting that Qms increased from 4.59 to 6.18. This Qms increase was not seen in any other damping method.
I would think that you would want a more brittle glue to stiffen the cone. I was actually hoping for a more pronounced break-up, knowing I could get rid of it later with slits. Maybe a superglue-coated cone?
