Mounted these on the patio two years ago and they're awesome. No shortcuts in the sound. They can cut through wind and traffic noise in the afternoon, and then at 1am wooden music sounds exquisite at lower volumes. I've heard lots of outdoor speakers that can go loud, and the O2-ARC's can also, but they sound superior to any outdoor speaker I've heard at any volume.
The first winter I brought them in, but have left them mounted the past two.
