But all that commotion is a thing of the past, now that we have the PSA Value Factor™!
Ladies and gentlemen, allow me to explain,..
It's simple; we merely use Power Sound Audio's unverified CEA averages of their own products as a reference by which all other subs can be judged! Kindly direct your attention to our first exhibit:
it's as easy as that! No more need to fuss about context! No more wringing your hands over trivial matters like compression, distortion, and linearity! Are you the proud owner of an SVS SB12 but curious how it fares against other subs? We can see very plainly that you need 2.6 SB12s to equal a single PSA XS15. Or, to state that another way, you own 38% of a XS15. For all you who have Hsu ULS-15s, know that you have a whole 90% of a PSA XS15, or a PSA Value Factor™ of 1.1! "But wait", you may protest, "can subwoofers really be reduced to a single number?" To that I say, don't you see, my friends, that ambiguity is a part of of its charm! Pay no mind that all these measurements were culled from different data sets, because with the PSA Value Factor™, such matters are somehow rendered blissfully irrelevant.
Lets walk through a few more examples...
Wondering how your SVS SB13 fares? Why it's a PSA Value Factor of 2.8 with respect to a XS30. In other words, a whole 35%. Who cares where this data came from or how it was acquired- all that stuff is for nerds! NERDS! "In-room extension? How did you come up with that frequency?" "GET THAT NERD!"
How does your Hsu VTF15h stand up to a Power Sound Audio XV15? Here we see it's a 1.2, or 83% of a XV15, despite the VTF15h besting the XV15 in almost every single CEA measurement and destroying it in compression, group delay, decay, and distortion performance. But thankfully we no longer need to pay attention to all that superfluous detail anymore- we have the PSA Value Factor™! PSA Value Factor™! PSA Value Factor™! ....
