[QUOTE="Chris Davis, post: 48680, member: 137"] Re: Water damage... causes Agreed 100% with your conclusions. If rust damage is uniform across all boxes, then it is probably due to condensation. The random truck placement would go towards making your point. On the other hand, I don't see how this could not happen uniformly, nor do I see how a single event could have caused it all, but you haven't gotten that far yet. I am no chemist by any means, but there is probably a very easy and logical explanation. Perhaps the composition of the surfaces, and/or coating, or lack of it? If I understood your posts correctly, the midrange magnet is essentially able to vent out through woofer ports? Maybe then the entire speaker is not able to vent out, i.e. perhaps you store them in boxes or under Cloud 9 covers or similar? Also, the speaker magnets most likely will have the highest metal mass of anything in your entire audio system. That would lend them to stay relatively colder for longer periods of time, thus developing larger beads of condensation that last for longer amounts of time and do the most amount of damage. As a side thought, let's say I bake a large party-sized (90 Oz) frozen dish in the oven at 400°F for two hours. Immediately after I pull it out, I have no problem removing the aluminum foil with my bare hands. It feels a little warm, but is not even hot to the touch. (In all fairness, I removed the foil first, then replaced it loosely before baking it). Bear in mind though, the dish itself just came out of a 400°F oven. The foil cover drops to room temperature almost immediately because it has such a low mass. The opposite would also be true. A thick glass casserole dish would burn the skin right off my hands if I try to handle it straight out of the oven. It has a higher mass, and will hold the temperature for a much longer period of time. So I wouldn't be as worried about the rest of the system, and that is why. Nevertheless, I might be inclined to have a quick peek inside the rest of the gear at least once, just to see how it is. [/QUOTE]
