Sorry, I discovered this discussion as it is wrapping up. As others have said - I came to open baffle speakers (Emerald Physics 2.8's) through having first many closed box speakers - Linn, B & W, Audio Physics - and also a 12 year stint with Magnepan 3.6's.
What I like about these boxless dynamic speakers is the way they - in my room, my system, my ears - seem to embody the best parts of the other two technologies, without feeling (as much) the natural limitations of either. Of course, I cannot own the box speakers where wonderfully heroic technology can also eliminate those restrictions (Wilson, Magico). I haven't spent much time with the more affordable speakers that seem to work with those factors, instead of conquering them (like Harbeth).
The Emerald Physics are more open and airy than my previous box speakers, and more punchy and dynamic than my Maggies were. They are not perfect, but it I am glad I came upon this funny piece of the loudspeaker landscape. I wish others could, too.
