Has anyone successfully put their speakers in storage for an extended period of time?


We’re about to upgrade our speakers, and am thinking of placing our existing, very good speakers in storage for possible future use in a second home or to hand down to our kids when they’re ready.  I cannot think of a downside, with speakers as opposed to electronics.  Any thoughts?

The rubber surround of the speakers will deteriorate  in a couple of decades. 

By then, there will no interest in them anyway.

You never really own a set of speakers, you merely take care of them for the next generation. https://www.youtube.com/watch?v=hjfXUpVtINE
Funny how they never show the watch gathering dust in a storage unit.
Still have my speakers purchased in 1979 stored in a closet.  Played them a couple years ago and they sounded good.  Been in climate controlled areas the entire time since I upgraded in 2002.  
On the wall in my garage is a picture of a Porsche parked in a garage. Below the picture it reads:
