What are the best sounding outdoor speakers?

Hi, just checking to see if anyone has any experience with the best outdoor models from Niles, JBL, Infinity, Polk, Bose, or others? Setting aside cost and sensitivity/efficiency, which of these is likely to sound the best in an outdoor environment? I'd like some decent bass and highs in terms of extension, good open, clear midrange, and decent definition and transient response. I'm looking for outdoor speakers that play loud and clear. Thanks!
