anyway to stiffen a spider?

I have been looking around the interwebz and can't find ONE answer, the reason I want to do this is my HX2 12"s are getting REALLY soft but everything about them is MINT and I was wondering what could I brush onto the spider to stiffen it but not make it so brittle that when it goes into full excursion it tears/fractures? anyone ever try this before?

 
Long shot, but you could try hairspray. May stiffen them a lil. Prolly have to repeat it a few times after they play for a bit, but should create a flexible, yet stiffer spider.
I would be careful around the tinsels though, heat and aerosol don't mix.

 
I was trying to find out what is used during production but all I'm finding is dead ends, I really hate to recone speakers that other then being well played are in perfect condition voice coils are perfect as is the surround cone and dust cap and from what I have heard reconing hx2's is a long shot for some reason? I think I'm going to test a couple epoxy's thinned down on some old speakers and see if I can evenly apply the epoxy then see how long/well it holds up.

 
well if it works on the test speaker and ends up on the HX2's that will be the real test there running on a 16mc2000d I think that might be one reason there so loose:laugh:

 
Yea, i have a couple old hollywood 12s that got weak on me a couple years ago, i bought some new surround for them thinking it would help, but did nothing, they seem to sound like they bottom out easily, maybe it will fix that, or even handle some more power lol, now that would be cool..

 
I'm just hoping to prolong the life of these at this amount of power you can tell there's just not enough control anymore, they where pretty stiff when I got them they had very little use but I think age caught up with them.

 
Stop wearin that hoe out.
I would but they sound so good on that kind of power and the coils still look new and that's getting beat on steady 30-60min a day for the past two months no stink nothin! just bass with an good amount of authority!

Any craft store should have it in both spray and brush on versions.
If I tape it off that spray would be the ticket for an even coating.

yeaz, tell us what really works.. Im wanting to try something of the sort, thumbs up for interesting thread lol..
I'll probably make a thread for it I just need to scoop a couple cheap woofers and gather materials.

 
coat the spider with resin. let sit for a week and then you haz stiffy
what kind of resin, I'm trying to think of other applications that require stiffening of fabric but nothing really comes to mind especially the amount of flexing a spider does thousands of movements per minute, what ever I try is going to have to really stand up without becoming too brittle.
