Yes huh. It's smaller and it moves faster, duh. The 15s are low and slow and pound out the mad lows. Be nice Mr. Tirefryr. OP, like others have said, I would chose build quality over quanity. The main reason is because I have taken the cheaper route before with less impressive outcome. Long story short, if I had waited one more moth, a week, or w/e the case may be so I can afford the higher quality sub, or for anything in life really, you don't wasted money, you have no regret, and your confidence builds in your decision making skills. You achieve the gratitude of making a wise decision as a person, as long as your results meets your need.
