The Seas coax's tweeter does have a bit of a flared throat on it that partially overlaps the midwoofer. Perhaps the movement of the midwoofer cone would be an issue at really high excursions, but at normal listening volumes, I did not notice any response problems, even when running it full range (i.e. without a subwoofer taking on the bass). And of course any non-coaxial design has inherent problems of its own. However, I'm not a professional speaker designer, so I defer to your expertise.
