I've heard all the DR Tops suffer from a muffled midrange / midbass area because of the bent horn. I can't see how he can overcome trying to fold frequencies like 900 hz

Frequencies much higher than 900 are "folded" and mutilated in different phase plug designs. The way it is done in the DR's is the driver fires into a short vertical diffraction horn, then split horizontally very close with a rounded hard smooth, small radius bend, which has a built in expansion to match the correct horn expansion for lower frequencies. Sort of like a modified w bin.
There are tradeoffs in all designs, these boxes are lightweight and super efficient and the high quality true horn loaded bass and mid bass that they produce is quite impressive at any size or weight.
The short bandpass horn of the xtro must be pretty impressive with the dual 15's as well, should be louder closer in, more like direct radiators. You would have to demo the boxes for yourself to figure whats best for your application.
