I sent an email to LEON asking about this but its the weekend and don't expect to hear back until tomorrow.

This will be an outbuilding but fully weatherproof, no chance of them getting wet. The only thing that would really be effecting them is the Humidity and Cold, obviously they wont be used in the cold weather. :)

I usually use sonance extremes for this type of situation but I was talking with someone a few months back and they said you can use standard speakers in this situation. As long as you know for damn sure they wont get wet or wont be subject to extreme humidity like a sauna or indoor Jacuzi room they have never had an issue.

Would like to get this quote sent out tonight!

If its in an outbuilding, you should be fine.  Only issue would be humidity, any speakers that use magnetic grills are going to be steel grills rather than aluminum so would be prone to rusting.  I use the axis-61 speakers in my garage and have had no issues. Garage is not heated and obviously michigan is subject to some nasty cold or humidity for most of the year.  

Your the man Joe!

Thanks for chiming in,no way we get that cold here on the east :)
