And furthermore, I think my skepticism is warranted because Klipsch's measurements lead to a strange result when you consider the design differences between their own subs, I don't understand how you are missing this. Who knows, maybe Klipsch paints an accurate picture of their subs' respective capabilities, all I am saying is I would be surprised if that were actually the case.
What are the similarities? You keep saying this without any substantiation of the claim. Does anyone think that the driver is the same? They both have BASH amps, but no telling whether or not they are manufactured to the same specs, and obviously one of them is different because it has additional tuning options. We all know that posted amplifier ratings can be unreliable. The Outlaw enclosure is a downfiring design, with the ports and driver aimed down; the VTF-3 MK4 has ports aimed out the back with the driver facing the side. Based on posted specs, the exterior dimensions of the EX are 90% of the volume of the VTF-3.4, and yet the Outlaw is 5% heavier. Those are a LOT of variables to make claims that they should perform similarly, particularly given the impact that the different driver can have.
Now I happen to *think* that they are probably fairly similar, but that's just a guess. And just because you want it to be true so you can point to the Outlaw measurements at data-bass does not make it so.
As far as the SW-115, if Klipsch's ratings for it are as reliable as people have found the specs to be for the RW-12d (such as Archaea's measurements), dual SW-115s should have plenty of output for a 2600 cubic feet room. The important factor to consider here is not the max SPL--which you seem to be fixated on with the "more SPL is always better" approach (which is not true as a generalization)--but the SQ of the subs.
