    Here is a site that will explain it for you:

    Igitur qui desiderat pacem, praeparet bellum -- Vegetius

    "I told her about my conversation three years ago with the political leader of Islamic Jihad in Gaza. "What's the difference between suicide, which the Koran condemns, and martyrdom?" I asked. "Suicide," he replied, "is done out of despair. But remember: most of our martyrs today were very successful in their earthly lives." In short, there was a future to live for--and they detonated it anyway."

    Bandpass uses two chambers and the cancellation between each tuned chamber is used to selectively pass only a certain range of frequencies. Very tough to do right because of the whole 2 chamber tuneing issue.

    Although it is difficult to find that "sweet spot", once you do it WILL be louder than ported, despite what others may say.

    But it will only be louder in that frequency range.....bandpass simply can't have as good as a result overall as a well-built ported/sealed box.

    the comparison between natheo's step dad and a bandpass are completly wrong. No one should diss a bandpass that bad.

    bandpass boxes arent all that hard to make. find your sweet spot(mine was 35 hz), then use winisd as a guide. its helpful if you use fiberglass, that way you can add/shave off to fit what you need. that and you can fill it with water and find out exactly what volume you got
