There is a reason why the PV15x jumps up to 949.00.
I could not agree more with everything said here.
Although I would not really consider just over 1" peak to peak xmax "low xmax". It may be low by today's standards. It is a trick of efficiency and that is why the 212 is a bit of a mid bass monster and capable of quite a bit of clean output in the most prominent bass region for $500.
Getting lots of good clean output at 20hz requires a fairly large box, ample power and a good bit of driver displacement. 20hz is more felt than heard and it takes a fair amount of SPL to feel it. This is why I do not feel it is in our interest to put out a "budget" or "compact" ported subwoofer at this juncture.
I also will not try and L/T or eq a budget, compact sealed sub to play deep into infrasonics. Simply because it would be difficult for say, a single average 10" or 12" sealed driver to produce enough down there to really be felt and enjoyed by anything but a measurement microphone. There are exceptions, with super high excursion drivers, but the cost goes up. Something like that is attractive because of the size, but there is greater cost involved because super high excursion drivers require more power. You end up with a costly driver and amp to get a small sealed subwoofer that is as powerful as it's bigger bretheren.
We did entertain offering the PV 15x cabinet with something like a 300w amp and a budget 15". but honestly....much of the cost of that model is making a large cabinet, boxing it up and shipping it.
It just did not make sense to skimp on components just to lower the price $100-$200. So we chose the best driver we could find and some rock solid, class AB amps that are proven and powerful as well as having flexible eq.
