I hope that I am not too late for the party. I had the VSM-M and VSM-MM in a 20x20 room with a 10 sloped ceiling. That room had a wide opening into a 12x20 kitchen. I had the speakers firing across the room due to it being square. At the time, I was using a Joule Electra LA 100 MKIII and a Belles 150A Hot Rod amp (not really expensive equipment, especially used). With my trusty RS SPL meter and the Stereophile Test Disc #3, I was consistently getting full output to the 31.5 Hz signal. Bass was less than my previous Revel F30, Gershman RX-20, and Paradigm Studio 60 speakers in the same location with the same equipment, BUT all had big humps in the 200 Hz and less spectrum when plotted. This most definitely gave the impression that they had more energy in the bass region (because they did), but to the detriment of the rest of the frequency spectrum (i.e. other frequencies were reticent).
As a side note, I never really understood the question of Can these speakers (whatever they may be) fill my room ? How loudly do those people posing the question actually play their stereo? Listening to music with 85-90 dB peaks at 4 meters from this setup described above was way too loud. Most of the time, a good level for me (in my current setup 3 meters from the speakers) is about 75 dB.
