Outdoor Speakers: Atrium 45 - Recommendation?

Hi all,

For $135, can I do better than the Polk Atrium 45's? (Link at Crutchfield )

I can spend up to $140 + tax in reality. I have no experience with outdoor speakers whatsoever, but bass response is my main concern. This is to cover a medium sized outdoor deck (30ft x 18 ft)

Thanks!
