If you actually tune that to a flat response, it would be a grand waste because just a few of those properly placed would tune up with those speakers and give great low end bass
. While the man and boy in me admire the effort, the realist in me facepalms.
If you have not seen or heard PL's system, how can you already have a firm opinion regarding the system's capabilities and relative value? Don't judge this book by its cover. Ultimately, the whole point of a system like this is to be able to tune flat to reference with zero strain, zero distortion... and then have the headroom to go where you want from there. The only relevant question is "how low can you go?" i.e. How much bass extension have you got? I get away with four 12" in my system, but I have ported my subs, so the cutoff is around 14Hz. What I experienced at the demo of this system was on a whole another level—and make no mistake, this is home theater not music. That kind of raw power can be used... all of it.
While your statement is correct—a pair of 18" subs would do for most people's needs—if you read my piece then it should be clear is that the capability of the system extends beyond the audible realm, deep into infrasound territory, and that some movies take advantage of this sort of capability. You won't find that sort of visceral impact in a movie theater, or in a typical "high-end" home theater.
I heard a rather nice Krell/Martin Logan system recently, and this system exceeded the Krell system's capabilities in some ways—with performance per dollar being off the charts. Sometimes, the term "high end" makes me giggle, because of all the pretentiousness that goes along with paying exorbitant prices in order to achieve some sort of symmetrical audio nirvana. Reproducing 8Hz at reference takes a whole lot of power and displacement—and if one were to pay "high-end" prices for capability like this it would cost far more to achieve this level of intensity.
Another thing I noticed—there were no measurable standing waves whatsoever. Bass response was consistent, no matter what one's position. With calibrated sound, and at modest volume, the quality of the bass was simply exceptional, because THD was so low.
