I've had two sets of these speakers Since 2010. The both continue to perform fabulously. One pair is installed in our kitchen/dining room. It provides music for that half of the house quite nicely. The second pair is installed on our screen porch. The speakers are under cover, but not in a climate controlled area. So, they do not get rain or direct moisture, but they do get subjected to temperatures between 15F and 102F. The continue to perform admirably with no issues whatsoever. I am using both pair to output the sound from Airport Express units playing Airplay music. I'm sure the semi-outdoor installation is not recommended by the manufacturer, but I have been VERY happy with them.
