There are 3 sound presets in total: Movie, Music and News. There is no possibility to adjust the bass. In movies and games, this is not so noticeable. But listening to music is stressful. Already at medium volume they clog everything else. Only a hum can be heard in the next room. They always want to do less. You get tired of them, the neighbors too. In fact: Excellent technique, which lacks one setting. Didn't know how to rate. I'll probably give it back. After a month of use: did not return) the problem with strong bass is solved by closing the phase reflex with something (for example, with a dense sponge), this is also allowed put the sub on a dense piece of foam rubber (the rumble seems to have gone away) I'm changing my rating to 4
