Actually, with metal cones, rubber surrounds, and vinyl-covered cabinets the speakers might actually be OK...

I would say first investment should be a big quiet exhaust fan (about $50 more than a cheap noisy fan) and then any Axiom speakers would probably be OK.

Alternatively, go for some of those "rock speakers" (built into rocks, not designed for rock music) that can sit out in the rain.
