    Hi there,
    Welcome to the forum.

    Looking up the specs of the box and the sub.

    I think your box might be too small.

    According to the sub manual, if you want a ported box.
    your internal air space needs to be between 1-1.5 cubic feet.

    I used this calculator to measure what your box has:
    I assumed your box uses 3/4 MDF and it comes out to a total of 1.81 cubic feet. But this doesn't take into account the vent or the sub woofer displacement.

    I have a feeling you might be in the ballpark.
    How does it sound?
