I think that all of us could live without the brand rivalries. One of the things that I think that people sometimes lose sight of is the legitimate brand loyalties that people like Tom (and other reputable sub makers) have developed over the years. And, in PSA's case, some of those relationship loyalties go back even further, to Tom's and Jim's days at SVS. Good designers don't suddenly stop being good designers and most people who have bought PSA products seem very well aware of that.
So, when Tom and Jim develop a new flagship sealed sub that has twice the number of drivers, in a unique configuration, in a bigger cabinet, and with more amp power, than any of their previous sealed subs, satisfied PSA owners naturally start lining up to try the new sub. There is certainly an element of trust implicit in that. But, there is an element of trust implicit in all ID sub companies to start with. Owners trust that good designers won't suddenly stop being good designers, and that they will stand behind their reputations and their products.
But, in this case, it isn't just naive trust. Anyone with even my limited understanding of sealed subwoofers can look at the ingredients I mentioned above and know that the S7201 is going to be a very serious performer.
Is everyone curious about how it actually compares to other subs on a frequency-by-frequency basis? Heck yes! That curiosity is only natural whether we are specifically interested in buying the sub or not. But, particularly if you are a satisfied PSA customer, you aren't going to require those measurements in order to try the new flagship sub. The same thing is true when other companies release their new flagship products, whether we are talking about JTR or Rythmik, or whatever.
The measurements are good to have, and as a consumer, I would like it if every sub could be independently tested. But, that is never going to happen, and I honestly think that we should all quit trying to obsess about it so much. Anyone who was at all happy with something like an S3001 or an S3601 is going to be far happier with an S7201, and that's really the bottom line. Eventually, there will undoubtedly be some means to compare the S7201 to somewhat comparable subs such as the S2, but meanwhile PSA will probably sell all the S7201's they can make to contented PSA owners and others, and justifiably so.
