    Unless you are referring to one of those aperiodic vents which make your box act as if it was bigger.

    I'm guessing maybe Bryan wanted to know the difference in using port vs. passive radiators (pr)?

    Pat,

    Don't folks sometimes refer to rectangular ports as vents? You know, the ones that are usually the width of the box but only a few inches high.

    For a dual Tempest sonosub? Hmm... [​IMG]
    (For a normal box enclosure, yes).

    My old sub (Def Tech Prosub200TL) use a TL vent in the rear. Which was like a slotted port/vent. Much like what the ACI emeralds use except bigger. I don't think it would be recommended for the Tempest.

    My dual Tempest has (2) 6"x20" vents which tunes it to 17Hz. Very easy to install. Not sure if this helps....Mike

    Bryan,

    That's still a port, they are just using the side of the box as part of it. Since you're talking about building a sonotube then you just need some PVC pipe or some flared ports.

    dual tempests....you might need to flare the 8incher. Depends on how big the box is (bigger the box, the greater the port air speed and cone excursion)
