Does anyone know how you can adjust the subwoofer yourself, if such an elementary possibility is not provided initially?! It's simply impossible to listen to music, instead of bass, everything just buzzes wildly . every time I expect a pleasant sound, but instead, one irritation and a desire to break this subwoofer. it saves a little, for example, when turning on music from the phone, the equalizer function on the phone - you can reduce the level of low frequencies. but in general it is of course complete nonsense. hand-assed Chinese completely crap brand JBL.
