    that's to be exact... get to within 1/8", namely 35 and 3/8 inches.

    don't build a bandpass.

    go sealed. its easiest and a hell of a lot better.

    Truly you know this from many other posts... POLK subs run better, cleaner, smoother, and LONGER in sealed boxed matched to them.

    Yeah, let me throw my hat into the "pro sealed box" ring.

    Theyre easier to build, can handle more power, are more forgiving of build errors and sound tighter.

    as said, sealed is definately tighter, more reliable, and easier to build, as well as better for your speakers' longevity, but if you're set on the loud bandpass box, you picked the right momo sub to do it with...

    be more careful than you think you need to be on breaking them in, just in case

    OMG! 141.5 on an Audio Control unit. (300 total watts)

    May not be W7 but that box plays notes that I only used to hear in systems that had 8 12's tuned LOW..

    IE ZZTop, Heads in Mississippi. Erich Kunzel, Planet Krypton
    Plays those UBER notes. :)

    The tonal range for application is great too...
    Nice and tight with the rumble for rock.
    Kick butt on the Rap
    Country romps

    With the little power I am pushing to them they are hardly moving..

    Cant wait till I put 800w to them....
