What is the best method of storing speakers?

[helfdene]

In October of last year, I was in escrow for the purchase of a home. It looked like a done deal, so I packed my Studio 60 Paradigms in the original packaging. The home purchase fell through and I've continued searching for a home. All the while, my speakers are still packed. I'm concerned with humidity since the speakers are wrapped in the orignal plastic bagging, some what air tight. Should I be concerned? Is there a better method of storing my speakers?

Thanks...
