I bought a pair of 12" energy subwoofers for my car that I would like to put in a ported box?

Question

unfortunately there is no numbers included with these subs, the only thing I know is that a .75 cubic foot box is suggested for a sealed enclosure, anyone have any clue how to figure out what size ported box and port would work with these??

Answer 1

If they only recommend a sealed box, then they probably aren't suitable for a ported box. Not all subs are suitable for ported boxes. If you want ported, you may need different subs. Putting those in a random ported box may give you a bad sound, and may make it so you blow your subs much more easily.

Answer 2

well most companies don't make custom boxed foe specific subs unless its the kicker L5, or L7's because they require a square box. but a box i call sufficient enough for any subs is the Q-logic dual ported box. expensive but delivers all the power clean
