I spent about 6 hours yesterday doing a comparison between the two versions.
The short story: Of the 4 drivers I measured, the NS version is a dB or 2 more sensitive, and can exist in a smaller enclosure, but will happily exist in the existing Statement enclosure. I currently have RS225's in one of my reference speakers, (not the Statements, but in a similar volume enclosure) and the original RS225S's in the other. So far any audible differences are so subtle as to be swamped by the room modes.
See my post with more plots and measuremetns here: http://techtalk.parts-express.com/sh...5&postcount=12
This is the 4 drivers modeled in an enclosure of similar size and tuning as the Statements. Red and Blue are the NS drivers:
