I bought 2 of these speakers 6 months ago, and now It's the second time I have to send of them back, because the subwoofer is gone again, but it was far away from its limit. It could be a very good speaker for its price, because it sounds well, has a lot of settings, but it seems, it's unreliable.
The coating is vulnerable too, so you have to use it very carefully.
Update 2023.04.11: I have send back them another time. I am nervous, when I bring them with me to work, if they can survive the event. I I can, I would send them back and get my money back.
