    They are comparable to the bandpass boxes because Bandpass Boxes have Ports. Yes, they get way better SPL then sealed boxes but it is at the cost of Sound Quality. If you can make a good ported however, the SQ won't take such a mean hit. There are many books that tell you how, some companies post Box plans on their website like JL Audio has a couple of different plans on their site, but other then that you have to draw up your own plans.

    Hope I've helped.
