Саб из LEGO

A very powerful subwooferbox - made only of LEGO bricks. Long version. Several of you think the box flexes under test at the end of the video. This is NOT true. The camera could not keep up during the low light conditions. The pressure around the subwoofer is huge and affects both me and the camera to move at nearly the same frequency. Therefore, it seems as if it flexes. Remember that it stands on rubber feet.
