As you all know I just bought a new set of MB Quart floor standing speaker model QL S830. The speaker sounded amazing when I played my first song in light piano melody and vocal from Jacky Chaung. Then for my second song I pop in Alicia Key. Again the piano part sounded amazing but when it hits couple deep bass that when it all started to go wrong. Now Alicia sounded like she is having a sore throat from a bad cold. I immediately called the saleman at YAWA Online. The saleman told me its fine and I just need to break in the speaker for it to play properly. He told me to play it in medium volume for at least 2 hours a day and its should be breakin in 4 weeks. Is this bul or for real? Please help, thanks.
