    Transmission line is a form of bass loading that uses a long folded tube or tunnel, lined with sound absorbant foam, wool or hair, to absorb the bass frequencies coming back into the cabinet from the bass driver. When implemented well (difficult) it can be very effective with deep extension, high efficiency and good quality, though you end up with somewhat large boxes.

    Here is some further explanation of transmission line design from PMC ,a British manufacturer of domestic and professional studio monitors who continue to manufacture high quality tranmission line speaker designs.
