I can understand from a visual point of view why coaxial designs are so popular.
Using a coaxial driver fullrange is however not a very good idea for good sound. The sound gonna be worse than the measurements shows because of the bassdriver modulating the tweeter like a variable waveguide when listening to real music. Can you hear this effect? - yes you can . Coaxial drivers done right , is crossed at 400 Hz to minimize this effect ( ie Genelec ) .
Im not suprised that Revel m105 sounded better when amirm did the listening comparison.

This shows the difference in directivity when the excursion is 3 mm or at rest. When playing music with bass tones and cymbals at the same time, you gonna have constant variations in the directivity .

Any downsides to coaxial design?
Isn't one a consequence of the other? - If the speaker has bad vertical dispersion, ceiling and floor affects significantly, and therefore must be treated. - If the speaker (coax) has good vertical dispersion, ceiling and floor affects less, and therefore are not as important to be treated?
