I agree cone area in addition to overall driver quality and build, optimal power delivery, and ability to pressurize air as a result is key to getting dynamics out of a playback system that can compete with the original instrument(s) in a similar room configuration.
This is one of the reasons I am a big fan of Walsh drivers. Drivers applied using the Walsh principles where sound is emitted from the rear of teh cone omnidirectionally benefit from effective application of available driver surface area, and the omnidirectional aspect results is a sound dispersion pattern more like that of a real, un-amplified, acoustic instrument. To get similar results with conventional driver technology generally require much larger designs and drivers that bump up the cost to deliver substantially.
