Break in time: Pioneer SW-8MK2 Subwoofer?

Can anyone give me a sense of how long it will take to break this subwoofer in?
I've never used subs before, but since the price of these speakers is so low, I thought I'd experiment.

My monitors are Sonus Faber Liutos which are extremely well-balanced by themselves, so at this point it's much too early to tell if the Pioneer sub will be a positive addition to my system. Room is 11 x 13.

BTW, I am aware that REL is often paired with Sonus Fabers. I don't want to spend that kind of money. :)

Thanks for any helpful info.
