These speakers are Bombproof,
I've now used 2 pair of the Runabouts outside year-round in every type of weather from below zero to 100 degrees for the past 11 years. They sound as good now as when I first listened to therm, They don't look bad cosmetically considering they were moved around the property depending on the season and are not always handled with kid gloves. If these ever die, which I really don't seeing for a long time, I will absolutely by another pair of these excellent speakers.
Worth the money!
