Please reread the entire article. Both 1337's are open through the back. and is confirmed by the box plan. The RS225's are bass reflex floor loaded.

My mistake, not sure why they call such a short duct an open back "TL" for the midrange - it's more like an open baffle with a 16.5 in long H frame on the back side. The 1/4 wave length freq of a duct this long is about 200 Hz, which I suppose can work if they use a crossover. You are saying that below 350 Hz, the driver will exceed excursion limit? Probably true. Not sure why this has anything to do with OP's request to get ultimate bass extension with the 1337 though.
