    No clearance issues with the MM842 either. Just need to figure which is better.... wish I had better ears :)

    Did have to trim the spades off the wiring to use the spring connectors on the MM, was a tight fit getting them connected outside the box. Wasn't able to rotate to have the labeling match up, if anyone cares about that stuff.

    Good to hear that the dimensional clearance is not an issue. After the new woofers settle in, let us know which you prefer and sounds better. :)

    I just went with two MM's. Have to return the other through Amazon so just figured I'd go with the higher end sub...

    Bringing this post back from the dead...

    What specs are we looking at to make sure that these subs will work besides the physical dimensions.

    Would these fit?

    Actually, although I know you are kidding, that would improve deep bass to some extent.

    The added "Volume" cabinet wise, with the area of the speaker and magnet reversed would help.
    God only knows why Polk had to do with such a tiny bass enclosure.

    I calculated it to be only about .7 cu ft. Most woofers this size, use at least 1.00-1.5 cuft.

    I know the answer was a narrow enclosure, but not only did we lose deep bass, but it is not all that efficient either.
