This was explained on AV123 ... but since the final info was moved here, the following performance parameters were used ... and it is a combination of objective data and blind listening sessions ...
1. Frequency response / linearity
2. Clean SPL delivering ability at frequencies starting at 16 Hz up to 80 Hz
3. Performance on music
4. Performance with movies
I currently have about 450 hours logged into this shootout, and have pages upon pages of notes.
Here is a slice of objective data which went towards the numbers as assigned: The ability of the various subs to deliver high SPL on difficult scenes. To keep this simple, let's look at the VTF-3 HO vs. the SVS PB12-Plus/2 on the lightning scene from WOTW.

VTF-3 HO W/O Turbo
