Subwoofeer has quite a high performance, it handles the bass well, but you must not expect excessive quality from a product for 3500 CZK, the back of the subwoofer resonates significantly when playing loudly and makes quite a loud sound, but if the satellites are playing loud enough, it's fine. I also use it at home for home speakers, where it excels, because you can't put it at 70% at home, so it doesn't resonate and I would recommend it if you don't have a decent one.
