Yah, its hard to describe how large it is in person and even when you put something in the pic for scale, it really doesnt come through. Lets use a feet (intended, hah!) analogy. If a 10" subwoofer is a normal man's shoe, and a 12" sub is a large man's shoe, the 21" is a clownfoot. Its just so large you have to laugh at it. That is most people's reactions when they see it.I also feel pics of my subs really don't do justice to how large they look in person.
