Jdanielh, I have a suggestion which could help you with your ESLs, protecting them against humidity, when you are away abroad. I learnt this from a dealer friend and it works well:
Get yourself a roll of that stretchy-elastic see through plastic wrapping and wrap it around your speaker, inclusive of the bottom electronics part, in about three to four tightly stretched layers. I assure you, moisture will not get through. You could of course also consider leaving them on all the time, as I do, but a certain fire hazard can of course never be discounted and mould could perhaps form all the same. The wrappings should do the trick, I'm pretty sure.
Cheers and happy listening! Detlof
