Speakers and glue......

That's a great idea Acurus. You'd have to be careful though, right? They would have to be totally air tight or you could end up with moisture in the bag. (and trap salt in there)You could put silica gel packs in there but what if they dry the speakers out too much?

I wouldn't sweat it up so much, I would throw in the silica bags and they will be fine. I am not sure they can be too dry..

You wouldn't believe how that salt air gets into things. I have some of those big Pelican cases that seal and apparently are watertight. Come back after a while and anything leather has turned to thick mold. The idea is to open your windows every day, but of course when you aren't there......

Thomastrouble. Csmgolf mentioned the Mark and Daniel line of speakers. The enclosures are made of compound marble. They look very nice and get great reviews.The Apollo II is in your price range. They're fairly large at 4' tall and weigh 170lbs each. They offer smaller models of floor standers as well, such as the Muse Ia at 85lbs, $5500 and also made of compound marble. They look very nice. I've never heard them but I'd like to after browsing their web site.

I have a couple of pairs of aluminum studio monitors laying down there now. They have been there for about a year, so I am going to open them up when I get back and see if there is any corrosion damage inside. If so, I think I will get some smaller monitors that I can seal up when I leave as one of the posters mentioned above.
Did you get a chance to Google Buzios yet?
