Hi!
I have not heard the specific Usher speakers you mention. The Ushers I have heard (929 and 6311), and compared to the VR-4jr and VR-2, I found to be boomier and less defined in the bass. So, if you feel the VR-4jr will be marginal with regard to mid-bass in your room then the Ushers are likely to be worse, in my opinion.
Have you given the VR-2 a try? The VR-2 may be a better fit to your room. How about the Consonance Eric 3? It is a little smaller than the VR-2. I would place the Eric 3 between the VR-2 and VR-4jr in terms of sound quality. I feel the Eric 3 is actually more revealing of detail than the VR-4jr but does not have the ability to bring the musicians in the room quite like the VR-4jr.
Just a note I am not a dealer. Nor am I associated with Consonance or Von Schweikert, other than being very happy with their products that I have purchased and/or auditioned.
Have fun!
