I have never quite understood why anyone buys costly stand-mounts, only to add subs because the bass is inadaquate. OK, stand-mounts may be good in a tiny room or as compuer speakers, but as main speakers in a fine audio system where the room is suitable for full-range floor-standers - no way.
Stand mounts often take just as much floor real estate as floor-standers and you then lose more real estate to ugly (I've yet to see attractive ones) subs.
Cost wise it seems a strange decision too. Extra costs are for stands (again never attractive), extra joinery for additional enclosures, extra amps, extra cables. All this is often because the wrong speakers were chosen in the first place. If you want good bass, get speakers capable of providing it up front. Ones with twin 10" or 12" drivers probably. These are much easier to set up properly than having to deal with 4 sound sources, that often lead people to resort to "room correction" DSP to sort out their self-generated setting up problems. Sorry, anti-sub rant over!
PS - Sorry - I've never heard either of you options, so ignore me!
