a ported box will produce lower frequencies, a sealed box will produce tighter bass. Really it's all user opinion, rock music sounds better on a sealed box, while rap music sounds better with a ported box. google the model number of your speakers, they should show you the manufacturers specifications for the right box to buildWhat kind of box should I put 2 alpine type r's in so they will hit really low and also sound loud and clear?
ported box will be louder and sealed box would be bassier i thats a word....i have 2 12 inch type r's in a sealed and wouldnt have it any other way
