I broke them in with a "bass mechanix" cd for about 30 min, followed by 20 min of 20hz at xmax, and a 10 min cool down before measuring. It's pretty normal for manufacturer specs to be off, as long as they aren't completely out of the ballpark it isn't a huge deal. I'm just glad it still works in the similarly sized small boxes. I haven't seen any 3rd party testing for the 12, but I imagine it will have similar results to the 10"
