Comparing the two models they are more similar than not. The passive model cabinets are dimensionally exact copies of each other, both triple vortex ported, both crossed at the same frequencies.
Different bracing? Because of the additional rear drivers? Thicker rear baffle because of the additional drivers? Have not found those specific details yet.
I personally have not heard either model but based on Axioms' own description of their products I would venture they are quite similar.
I would speculate the rear firing drivers create an ambiance that some/most audiophiles will find pleasant.
The DSP switch and the actual physical positioning of the speaker offers the type of tweaking we all enjoy toying with.

Bye the bye, which Bose model does an LFR-1100 without the rear firing drivers sound like?

Ok, I'll allow you hear what you hear as so would I.
