    Hi,

    I recently aquired a 12" subwoofer box. How do I know whether its sealed or ported? I can't see any "ports" or gaps in the box, so is it safe to assume its a seal box. Or is it something to do with the design/shape?

    Thanks

    Its a sealed box. My 12" sub is in a sealed box, gives it more of a punchy bass ;)

    Aside from the hole that the speaker sits in, if it has no holes, then it is sealed.

    Ported = a hole/holes in the box

    Ported boxes drop lower but aren't as punchy as sealed boxes

    Sealed = no holes except for the one the sub goes in

    Sealed boxes don't drop as low but the reponse of the sub is better.

    Hardly.

    I would say it depends entirely on what kind of music you listen to.

    When i tested out various boxes and setups, in my saxo boot :o the ported box was miles louder than the sealed.

    It also depends on the Thiele & Small parameters of the speaker and how the box has been tuned, ie for a peak, a low rolloff or a ripple.

    i found a good inbetween was a 10" ported.

    10's are usually a little punchier than 12", so a combination of 10" and a ported box worked well.

    unless you just wanted thump of dance music, get sealed, or low rumble of D&B then ported.

    Sealed boxes are generally quite a lot smaller then ported ones. Should be, at least.
