What can i do to keep surround from rotting?

[JoshC 10+ year member]

Had some crap get into my box this week so i had to pull the sub to get it out. I noticed that if i rubbed my fingers on the surround a bit of it would come up. Not alot just tiny bits would ball up, is there anything i can put on it to keep it from progressing? Subs around 2 years old but still beats like a champ. Its an OA 12

LOL. Welcome to the world of Chinese parts and the race to zero. Sadly nobody will pay what it costs to build a good woofer out of quality parts so play it til it breaks and buy a recone.

Once it gets really thin or starts getting holes in it you can get a little more life out of it by reinforcing with gorilla tape or just painting it with rubber cement.

you can use a neoprene rubber cement that is thin and paints on. i just had to do that to some subs from 1996 (yes, i've had them that long). it painted on easily and should prolong their life.

surrounds failing after 15-20 years is acceptable. after 2 is B.S.

Yea its disappointing, but there just barley starting to and they have been threw 2 100 degree plus summers. But its only a $140 sub and it does sound great still after 2 years of 1000wrms

Race to zero. The same tier sub built in USA with American parts would MSRP over 400$.... then again it would likely still function in 20 years.

Totally agree. I have plenty of subs 15, 20 even 30 yrs old. Its mainly cheap foam that falls apart especially if its in the sun.

instead of a whole recone kit, you can look for a refoam rubber surround kit instead and shave off a few bucks on the cost, unless you want the stiff suspension and all that. I would look into getting something from corey at SPL audio, he probably has some parts that will last pretty long that he can sell you.
