closed boxes need to be calculated also although they are easy and can be done with simple tables. Otherwise you lose control of F3, Qts and efficiency. Assuming reasonably low F3 I consider a low Qts(BELOW .707) essential to quality bass. Unfortunately low F3 and low Qts usually leads to large boxes without equalization. Over 30 years ago Henry Kloss published the math that showed a relationship between these 3 factors. Change one and at least one other must change.
The other problem with closed boxes is that since ported designs are in, most drivers are designed for them and not for closed boxes.
