For humidity protection you could seal them in doubled plastic bags and packing tape seal with dessicant dryer packages inside the bags. I don't know how much heat you are talking but I imagine some drivers can stand much more dry heat than others. Expect to be disappointed with drivers using foam surrounds or plastic cones I'd think. Come to think about it, you don't have to live in the tropics to be disappointed by such drivers.

Caveat: No intent was made to inflame the owners of good drivers with polypropelene cones. However, if you have foam surrounds, well that's your problem, fortunately not mine.

I am talking about 35+ c in summer . humidty 90% +

HiSPL it would be cheaper for you to buy your own . because I not going to pay the shipping to send mine to you

I have heard that what attacks surounds are light and ozone
So if they were in black plastic bags I think you are covered on that

Well, displacing the air with nitrogen would help I'd think.
It seems that carbon dioxide is much more available though.
I've always wondered if CO2 would work since the oxygen is pretty tied up chemically I think. I don't know...

If you put them in a with dessicant and AWAY FROM LIGHT, you would be OK I think. Also packing the bag in a big box with a bunch of blankets/clothing around them would cut down on temp swings.

If you use a big bag, after a couple of days you could isolate the dessicant in an area near the mouth, and tie it off, remove it, and add a new batch of dessicant after the first batch had done its work, to make sure the dessicant is fresh and functional. Then I think you would be set for a couple of years or so....

Also remember to place the drive units in the same orientation they would be in in 99% of speakers, facing fowards etc. If they are stored as per a down firing application the weight of the cone and time can cause it all to sag, which is not what you want. I have my 10" csx stored in the XLS10 boxes on a shelf placed vertically.

Yes, that trick works nicely.

When I get new drivers in, it seems they often have a bit of cone sag, and usually towards the magnet. Storing them face down sometimes corrects that problem.

The funny thing is, I have a Peerless sub in my closet right now, stored face down, with 30 coins taped to the back of the cone to undo a little cone sag. Last time I checked, it was just about perfect.
