I love these speakers. I have 4 inside my shop and 2 outside. Great bang for buck on an outdoor speaker. I went with these A6's inside the shop after having the 2 A6's outside the shop and liking them so much.
Great sound; Good Value; Great speaker if you want a much better than average speaker without breaking the bank
Over time, say 3 years, the grilles come loose; Nothing broke and they didn't fall, but one side of both of my previous A6 on the outside of shop came loose; I simply pushed them back in; Didn't bother me enough to not buy them again
