I've had no issue with these speakers operationally over the last two years.However, if your speakers are in direct sunlight for the summer as mine are (I take them in for the winter) the White plastic WILL turn yellow in color where the sun hits them (UV damage?).If this upsets you, either apply armour-all or some other UV auto protectant to them liberaly (at your own risk) or find yourself a black speaker set.
