Cones and domes have fundamentally different off-axis radiation pattern. Shortly, domes have smoother off-axis behaviour. On the other hand cones have more effective on-axis radiation area (with same diameter) which helps in low end of passband, higher spl/less distortion. Difference in "sound" is not so big, if any, unless either one is pushed out of it's comfort zone.

Legendary Zaphaudio measurements, first 3" dome , then 3" shallow cone

We have some modern large domes, eg. from Devialet and Accuton.

Reminds me of the Design Acoustics D12 full-range loudspeaker of the 1970s :)
Or this one from even earlier:

FWIW, the designer, shown studying his creation, is the conductor, Hermann Scherchen.
