Absolutely incomprehensible logic of engineers. By default, a proprietary "improver" of sound is enabled, which only spoils it. You can turn it off, and the middle with the top will become much prettier (taking into account the class of the product). But! The next time you turn on the SB, it will automatically work again! This is the main claim. The subwoofer is not for cinema. The lower limit of hertz is 40. If you conjure (otherwise it mumbles) with the installation site, then there will be a sound like that of bookshelf speakers or small floor speakers (of course, budget ones). In general, in a month it will play out. The sound will become louder. But, you need to understand the level and purpose of the application, so as not to be disappointed.
