SoundPath audio cables deliver a spacious soundstage, solid three-dimensional imaging, sparkling and airy highs, an uncolored and neutral midrange and tight articulate bass
so any serious data backing their claims might not be forthcoming.
I'm a big fan of data but in this particular case I think SVS would be doing themselves a financial disservice were they to disclose the hard data for the product they spent time and money developing. After all, they are a company that operates to make a profit, no?
The product though is based on sound scientific principles and they could, without financially shooting themselves in the foot, disclose a generic graph. By adding a mechanical compliance they have in effect introduced a second order filter no different in the general sense from an automotive shock absorber, vibration absorbers as you might find in chain saws, mattreses, or isolation type devices used to attenuate vibrations in fields such as electron microscopy.
If you were to plot a graph with vibration intensity on the Y-axis and durometer reading of the product on the X-axis, you would get a graph that somewhat resembled a 'U'. The understanding is simple. With low durometer values the sub fully compresses the product with neglible attenuation of the frequencies transmitted to the floor. As the product becomes harder/stiffer there is now some bounce to it which allows for some second order filtering where the vibrations are attenuated by being converted to heat within the product. Increase the hardness even more and it becomes a poorer second order filter.
As to the cable comment, I don't think you're reading it carefully enough. The cable is delivering though qualities because the signal is passing through it. The qualities themselves are a consequence of the speaker and how well it's placed in the room. Good speakers placed well and with good recordngs do convey a sense of spatial qualities such as localization in one's head. SVS is not saying the cables have some unique property peculiar to them that permits this. It's just ad/marketing copy. Kal Rubinson, I believe, once wrote that when using a particular cable in his system he found that there was no cable he had ever used that was quieter. Some might read that think that cable was unique in this regard. However, the correct interpretation is that the cable being used was just like every other cable, they were all equally quiet.
