Point Source vs. Pistonic. Which better?

Speaker Asylum

General speaker questions for audio and home theater.

Audio Physics says their drivers operate like a point source. Revel talks about their drivers achieving "true pistonic" movement. Which is better? It doesn't seem that Revel's inverted domes could operate as a point source.
From what I've gathered a point source will give wider dispersion and is the only way to get the true tonal decay (or tonality) of a musical note.
Does anyone know which is better or what is trying to be acheived by these design methods?
Thanks
