i was thinking of 4 cubic feet but i cant find anythign on this sub. no info at all since this is a custom made sub so i dont know how big of a box i should make.. its a super sub, anyone can help me?
a 5cf box would be louder than a 4cf box at lower hz, so yes in this case it would probally be louder. but if you were to play anything between 40-60hz you probally couldn't tell the difference between a 4cf box and a 5cf box.
