I operate the set with a Denon X-3800H receiver. Everything is actually great, but the subwoofer flutters unpleasantly with stronger bass, as if it were overloaded. Indirectly, it's not, because when I solve the problem, I hardly have any more bass. I also have this problem with manual settings or automatic configuration. And no, the subwoofer is not faulty, as I have a Klipsch connected that shows exactly the same problem. Does anyone know about this problem? Would you also like this as a film?
