Woooaaahhh!! Let's slow down a bit there and not oversell this
I am absolutely going to provide some empirical tests with as rigid testing constraints and accuracy as I can muster. This will just be a data point, though. A true scientific test would have to involve more than one subwoofer; more than one stage design; and more than one room type. What if my results are only what they are because of the specific ratio of my specific subwoofer to the specific size and weight of my stage compared to the thickness and breadth of my concrete slab? We can't know until there is more testing done.
I would really love to see a series of tests like this done, by people with a variety of variables. What variables really matter? We'd need a bunch of data points to start seeing where the patterns are.
Really, though, I think HopefulFred absolutely nailed my motivation for this:

He's not wrong, but it's not that simple. If budget and space and modeling are all available, then sure, you do it the way that the pros do it, but for the DIYer, there are often compromises. Granroth is trying to figure out the value-added portion of the thing so that folks up can make informed decisions about the trade-offs.
Really, I can't say it better that that!

But more seriously, I'm not very convinced of this. I realize that I'm now standing here without a shred of real evidence disagreeing with a guy with years of experience on scores of theaters! Yeah... not very firm footing on my part.
Still, I've read through so so many build threads, including quite a few created using Erskine plans. What's notable to me is not how drastically different they are, but rather how remarkably similar
I'll concede that there probably are subtle differences between the builds that I don't notice that really do make a difference in specific rooms with specific equipment (choices which also tend to be more similar than dissimilar, it seems). How noticeable are those differences, though? Do you need sensitive instruments to measure them? Maybe special auditory and visual training to see and hear them?
