The VR4se has a much fuller bass than the SR model. They have tightened the bass up considerably until now it almost sounds a touch lean. The rep that was demonstrating them mentioned that the bass in the SE version was a bit sloppy.
I can't say if the tighter bass has opened up the midrange or they have improved it but the SR sounds more open.
I did notice one thing about the speaker I didn't like. The sound didn't sound as integrated as I have heard from driver to driver. The SR uses 4th order slopes and this may account for it or it could just have been a room thing.
I also thought the sound had a tendency to sort of "Stick" to the front of the speaker even though it had good center depth. It didn't really extend past the outside speaker boundaries nor was there a lot of depth directly behind the speakers.
I'm always leary about writing about something I haven't actually had in my room. With the rep's comments and the sound, I can say for sure the bass is considerably tighter. After that, it's all impression in the room they were demo'd in.
