Do I need to renew gaskets on SBLs?

[ariegur]

I am using my SBLs since the last 10 years at the same place.
I see that TomTom are selling gaskets and I wonder if it is a good idea to renew the gaskets after a long period of time?

As long as they are in good condition, I wouldn't have thought so. You can test the gasket/silicone box seal by pressing the bass driver in and it should come back into position slowly. If it returns too fast, then there is a problem with the seal. If the gaskets are in good condition then I would not replace them - the silicone seal is then the important bit.
