I've listened to the VR4-JR and VR4-SR in the VSA line.
The JR is a little bloated in the bass while the SR is much more refined. Neither gave gutwrenching bass extension though.
For that you may want to go with a subwoofer to compliment the speaker you choose.
Most good speakers sound good at low/reasonable volumes with good equipment upstream.
I don't think you necessarily need an efficient speaker to do that. In fact, i have found the opposite is often true. Many highly efficient speakers doo not oppen up in the bass until they are run fairly loud.
Try a line source speaker like an electrostat or planar. The large surface area can give a great sense of depth and immediacy at low volumes. You will need a stove of an amplifier to reach very high volumes though.
You can always implement tone controls.
Good luck!
