HTD has Level Two outdoors for $59 a pair. I also recall seeing some site, Oudoor Speaker Direct, I think, that had some decent looking models with good specs for good prices. Also look at the AR Edge Pro's at Acc. 4 Less. Good Luck.
The only reason I'd lean towards getting the Russounds is the fact they are fully sealed in the back. If the speaker is totally exposed to weather this might be a potential issue.
The HTD ones look like a bargain but I'm not so sure..Still for that much if they crap out so be it. It's only a $120.
