Interesting... either I'm missing something or there are more versions of the AX-5 than I thought, ie more than just wedge vs box. The pictures I have seen are of slightly taller boxes with ports on the front, but yours appear to be sealed cabinets (or the ports are somewhere non-obvious or I'm blind).
There also seem to be different grill arrangements, with the grill covering the entire front in some cases but only coming ~3/4 of the way down in others.
Here is another flavor of AX5, with ports and a taller enclosure:
