JBL 2226 woofers tend to be pretty stiff out of the box. They're underdamped at first. The alignment shifts to where it is supposed to be after several hours at moderate power. You can move some woofers back and forth by hand to do this "break in" process, but I prefer to let the motor do it for me.

Another thing about the JBL 2226 woofers is they change characteristics above about 10 watts. This is the power range they're designed for, and below about 10 watts, they're a little bass light because of alignment shifts. They are designed to be augmented with subs anyway, so you shouldn't ever notice this, but it's a fact, nonetheless.

I prefer this sort of conservative alignment. Better they go this way than the other. I hate speakers that get boomy when they heat up.
