Back about 5 months ago, I bought a used pair of MGIII for $300 that are sonically in perfect shape. They were stored for the last 10 years in a storage facility, away form the sun and completely unplayed, so there is currently no delamination or buzzes. They currently sound really good.
I am preparing to upgrade some x-over components, replace the socks and doing some structural improvements. While I have them open, I was wondering, is there anything I can do, proactively, to prevent possible future delamination?
Any recommendations would be appreciated.
