Thanks for the comments and compliments guys- I'm glad you're enjoying the sound. Phasecorrect- regarding the 8-10foot listening distance you mention:
There is nothing special about a first-order circuit that demands this distance, except that first-order designs do have a "focal point", which is set mostly by the arrangement of the drivers.
This is why our new Continuum 3, like its forerunner the C-2, lets the user adjust the drivers for proper "Soundfield Convergence" at most any listening distance and height. With that, we hear substantially the same image size, sharpness and depth, and dynamics and tone balance whether at six feet away or beyond 20 feet.
The Europas, as a two-way, can be focused by tilting them, or raising or lowering them, for a listener from four feet to >20 feet.
What often happens with any speaker as you move away, is at some point you are sitting beyond the nearfield/farfield transition point (where the room's reverberation is as loud or louder than the direct sound)- as you suggest in your title.
That is why we recommend the setup in our manuals- so that you'll either be completely inside the nearfield zone, or at least no further back than just inside the transition point between the near and farfields.
