Advent refoam (again)

[ppitt1212]

I know this is an old worn out topic but need to ask.  I will be re-foaming four NLAs 10" woofers.  They are the metal frame square magnets.  The old foam attached to the cone between the cone and the frame.  This will make it hard for old glue and old foam removal (not impossible though). 

My question is that i saw a big seller of the foam replacement parts had a video of simply gluing the foam to the top of the cone (easy peasy). 

Is this just wrong?

If you are able to do it, do it the way Advent did it. Surround flange on the bottom of the cone. It's not that difficult. It would bug the hel* out of me if I did it wrong. Some people, even so-called experts/professionals, are just lazy.

Thanks, will put the foam in the same place it was.

It is just plain wrong.

The motor has about 1/8" linear Xmax, when you offset the cone in the wrong direction you

take away from what little is already there.

ppitt1212, refer to this post by Doug G. on this forum - Easiest Refoam Method Yet For Both Masonite and All-Metal Woofers. This post describes a method for the attachment of the foam surround to the under surface of the woofer cone which is not difficult to accomplish.  I used this method on mine and it came out very  well.
