My single 12 box was an amazingly low hitting box peaking at 40hz, yet my current 15 box is tuned high and peaks @ 64hz . Anyways, enough of my rambling.
Get a good set of subs, and a good amp to power them, and compliment those items with a quality box tuned correctly for what you desire, and voila, you are happy.
if im correct...2 subs can be diffrent sizes and the smaller one can be louder. but it cannot be lower because theirs no way it moves as much air... im an sq man and thats the theory ive always adhered to
