I can't really help on which speakers to get. I got mine (listed as indoor/outdoor) about 9 years ago, can't really remember the brand.
As to placement, for about a year I've had mine in our new house under the eaves of the roof, placed pretty close to the overhang. Before that, I had them at our last house for nearly 8 years with one right under the overhang of the eaves and the other on the side of the house. Technically under the eaves, but with the placement and pitch of the roof, it was probably 15' or more from the roof eave, so pretty exposed.
I didn't do anything to protect the speakers or the connections, and left them up year round. At 7600' elevation, we had snow from October into May, so they got plenty of nasty exposure to the elements and they did just fine (and are still doing fine).
Bottom line, if you've got them under the eaves of the roof, I doubt you'll have a problem.
