TWO SUBS IS NOT NECESSARILY BETTER THAN ONE SUB THAT IS TWICE AS GOOD. on better subs you get higher quality components=less distortion (usually with good companies at least), instead of 2x what you had before. for that reason, one would be better served with one sub twice as nice. this MISCONCEPTION that two subs is perfect is a bad one, and honestly hurting consumers because they are buying lesser quality subs in order to be able to get two. if you must have two, then you should double your budget so you can get two subs of the quality that you initially intended to get only one. ive said this before, so no need to dwell on it anymore.
