down firing bass works that way lor...u will not get exact response of the bass like normal woofer...
the midrange and twitter is the 1 giving clarity to the bass...which sits on top of the table... which is why is set to max...
so i hear the bass fired from front but it rattles whole room....

u can try holding the subwoofer with nice bass song and u will understand what i mean...
u wont even feet it hitting you, but place it downwards under table where it can reflect all the bass back and boom...
there are two kind of subwoofer and two type
front face solid type or down face soft type...usually is categorize like this
the pair of tower speaker bottom also have a woofer to handle higher frequency bass.
the sound isolation or you can call your room isnt compact enough...thats why when the bass is heavy it rattles the whole room

...which by then acoustic sound absorbing foam comes into help.
previously my rojak HT setup room doesnt have any of the acoustic foam stick to the wall...and i get all the rattles when bass comes in
after spending a few thousand rupiah

....the rattles gone
also....usually down firing subwoofer is good for music only
