Pertaining to your second paragraph of question/observations, perhaps it would be best for you to think in terms of "concentration" of energy when thinking about which type of speaker would best suit. I often use the analogy of straight line wind versus tornado. Both have powerful fronts, but the straight line wind is a wall of sound, overall less concentrated than tornado. Tornado is tightly packed and while less distributed, more forceful. Now, apply this to panels and dynamic speakers; the panel is like straight line wind, while the dynamic speaker is like tornado.
You will overall get more tightly focused center image and bigger variance with dynamics with dynamic drivers. You will overall get more diffuse center image (larger and less dense) and less variance in dynamics. Forget the "walk around" variable; it does nothing to determine the final happiness with the seated listening to a speaker system - unless you will be up and around while listening constantly.
When I establish a system with this particular genre of speaker my goal is to claim the best of both worlds with an open baffle dynamic speaker at least 60" tall. I would not wish to settle for less than at least 2 15" woofers per side and a speaker ideally 60" or taller. There are some wonderful speakers of similar (but not identical) ilk mentioned here already. The PAP Horn 1 (or other variants) does not meet the height criterion, but that is easy fixed with a bit of imagination. :)
I advise you to keep your current speakers, and buy new ones as well. Swap them out whenever you feel like it. You will begin to hear substantive differences, ones that cannot be mimicked by the other. It's a great way to gain appreciation for the vast palate of sound available, and to slowly determine which technology suits your ears the most.
