How much throw should they have when not attached to anything. I think the book says something like 7/8 of an inche. But when I installed them and working them by hand, I barley have that much max deflection. I installed them just like the book said with virtually no gap. Or is it just so small compared to my Funtana that has about 3-4 inches of throw by hand? I need to pick up a throw meter just to get exact numbers to be more specific. But it just seems so small.
