alright, the higher the Xmax the harder it hits right? Im not sure so correct me if im wrong. But when i was looking at some subs, i found one with a larger Xmax than the RE XXX, and those are supose to be the loudest or close. The blueprint 1203 subs have an Xmax of 51.1 and the RE XXX have a xmax of 39, so how is it that they are louder, or do you also have to look at wattage because the RE XXX has 1600W RMS and the 1203 have 1000W RMS,, please help.
