Oh well.........
LOL! 
No, it stands for Mass Loaded Transmission Line, a more technically correct way to decribe vented pipe designs that historically were usually referred to as a 'tower' or 'column' style speaker.
Nothing fancy, just a fairly simple design that can be either two isolated compartments or a single compartment if either the depth can be increased to 17.5 - 18" or a small cap is added to the rear to cover the end of the horn driver since it will require a clearance hole in the cab's rear panel. The basic layout of the components would be per pg. 20's '800 Hz VOTT' layout except with the vent down near/at the bottom of the much taller ~42" high cab.
I don't do drawings, but if you decide to go one of these routes I can fluff out the rest of the details.
