Best Outdoor Speakers

Spring has sprung and a (not so) young man's fancy turns to...

Listening to tunes and the occasional baseball game while relaxing with a cold one on the deck.

What I am looking for is a pair of speakers that is pretty rugged that sounds decent for less than a grand. The deck is covered and the speakers would be mounted on the wall. While they would be at least partially shielded from the elements, they would be subject to some temperature extremes. I'm planning to power them with a vintage Yamaha receiver (75 wpc).

Any suggestions would be helpful.
