As you know, I bought a Monolith sub last year. Having seen this bizarre thread, I read it and then went and checked the feet on my sub. I hate to make fat chick jokes, but, if my sub was a 5'2" 250lb fat chick, she would have on size 5 shoes in those little rubber feet. At first, I didn't think there were any feet at all. The sub from the side (sitting on carpet) doesn't look like there's any feet. (another fat chick joke, but I will abstain). I had to pick the sub up and feel for the feet. (yet another fat chick joke.....abstained).
These rubber feet (they are rubber and not hard plastic) are really tiny and they have little nipples on the end. (yet another fat chick joke......abstained). I don't see them doing much of anything except keeping the body of the sub off of a hard surface (oh my, another ......). They certainly don't do crap on a carpeted surface.
Since they are rubber feet with little nipples on them, I wouldn't drag them across a hard surface. But the dang sub weighs so much if you're moving it that's probably what you're gonna do unless you have help.
This thread seems to be a lot of comment for not much content. I doubt little feet on subs do much of anything.
@shadyJ would probably know if anybody would since he tests them.
