you can still have a groundpounder thats only 20 cubes thatll do great numbers a 35 hz and down.

and i was bored today and said fuck it i'll shrink the wall down so i shrunk it to roughly 20 cubes after all the displacement and tuned it to 37 it moves a bit more air but i'm goign to wait till i get it on the meter before i make this perminent
