my environment is fairly protected. you can see the two speakers under my pergola in the first pic. for a few months they were in the sun full time and turned very quickly yellow and you could tell from the pattern that it was from the sun. after a few months we put a retractable awning system into the pergola and they are under cover much of the time as seen in the second picture. the pool has an automated cover which is closed 95% of the time and the pool equipment is > 100 ft away.
