Axiom Home Page Forums General Discussion Advice from Axiom Owners In-wall speakers for outside use?

Is there any reason why the in-wall (flush mount) speakers would not hold up to the outdoors?
The Mrs and I were sitting on the front porch last night and *she* suggested that it would be nice to have some speakers on the porch, mounted in the soffit, to match (source wise) what we were listening to inside.
They would only see heat and humidity (95F (35C), 95% RH), no direct rain or sunlight.
