It is not the sub that will shake the neighborhood or the apartment building with its intensity and noise. However, for a room up to 25-30 square meters, it produces more than enough intensity, but the most important thing is that it covers the entire range of lows, resulting in a fullness in the space from the bass, without exaggerations. There are few subwoofers that go down to 22Hz. It will definitely require proper adjustment with measurements in the room to play correctly.
