Good questions. I found the brochure from the ADS MS3 and this is what it says about the cabinet. Remember this is about 15 years ago.
"Made with heavily braced 3/4 inch MDF, the cabinets are key to the MetroSub's performance...."
"The LamFlow ports equalize air pressure across the speaker cone. The size and placement of the ports prevents the cone from tilting as it moves, thus keeping distortion low. The port geometry optimizes the Laminar Flow of air, which eliminates the "wind noise" produced by conventional ports.
You will have to decide for yourself if the description of the ports means that they were used for bracing. They were probably pretty sturdy as they formed a significant part of the bottom of the cabinet, and they were used to prevent the cone from tilting as it moved.
And, you are correct, as far as I can tell, that there was no flaring of the ports on the MS3.
I only remember the ADS MS3 because it was one of Tom Nousaine's favorite subs for several years, quite a while ago.
