    The reasoning behind the lower SQ ported is the roll off. Play within the bandpass and it sounds fine. Sealed wont have that roll off until the sub loses. Build up a good mid range and its fine.

    The majority of sound quality cars have put a lot of time and effort into their installs, they chose what they chose because it makes the most sense and because it is what works best for their vehicle. Wether you like it or not, IB or sealed is optimal for sq, you can get a ported enclosure sounding very nice, but it still won't have the articulation.

    And so a ported box is more appropriate for such subs to prevent excessive damping from robbing low end ouput.

    If I'm wrong somewhere, show me, because I really would like to know.

    creating a proper sound wave. Step one, turn it up until clipping. Step two, done.

    Mark was single seat I think. All I'm saying. If you design the ported alignment to do only what you need it to do its just as good as sealed.

    But they have been proven to win??? How is that??? There has to be give and take. If you want flat out of ported you must lose output. If you want output you must lose flat.

    Sealed and IB have time and time again been proven to win out over ported though. There of course will be exceptions to the rule.

    Re: sealed vs ported for sq that packs a punch for a single orion hcca 10.2

    When I tune for SQ you don't even know I have a monster ported sub stage in the back.

    Back to the op. are we taking about real SQ or just something that sounds good?

    Mark does both single seat and 2 seat. I believe that the only reason that he beat mark at this show was due to his install, Mark's sq scores were higher than Scott's IIRC.

    When I tune for sq, you know that I have a very flat, very articulate sub stage.

    He already stated he wants more daily than sq.

    Times are changing, software is getting better and so are drivers.

    I would put money that the right IB sub in the right environment will score higher than the right vented sub in the right environment.

    Can you jump over to the meter after you're judged and put up a good number?

    I don't need to. My sub stage gets more than loud enough for me. If I want an spl car, I will go build one. Daily driving and sq mix very well in my book.

    So essentially what you are saying is that pressure is higher in a sealed box and that over-damps a woofer with a stiff suspension?
