SPL rant

Well I thought this guy's point was that quantifying SPL with a TL reading is pointless because what should matter is what sounds loud to one's ear.
I thought your first point was that the human ear places a subjective i.e. opinionated value on SPL, making it biased and in a sense uncomparable to TL readings, which quantifies SPL to a given unit of measurement making it undeniable, like the fastet time at a race track. Take for instance taking a 12 second car at Tim Horton's. Sure it looks fast when you're standing on a the side of the road watching it do a 1/4 run, especially if you're at the end of the track. However compare that to a plane however many thousands of feet in the air. They look like they're crawling when they're moving faster than we can get our Timmy's rockets to go. Subjectively the car is going crazy fast while the plane barely moving. Quantifying those examples however, you could be comparing 85 mph from the car vs 350 from the plane. The plane is therefore the faster vehicle. Loudness vs SPL is in the same boat. As loud as 33 hz might sound, it might only do a 145 on a TL, while a 155 may not sound as loud, but the results are undisputable. The second maybe that its best to take baby steps and absorb everything you can through your own work before going to others, like going to the library before you decided to get a tutor, yeah?
My point was that if I wanted to learn something I'd start with the best teachers I have available to me so long as they'd be willing to teach me, after I tried to figure out what I could on my own. This is of course assuming that I, like someone who may have read your statement had exhausted all other resources, where I think you were referring to someone who just started yesterday and their first step was ask the greats for help. Again going back to my pre CCA days, I thought I knew all there was to know about car audio and what made something loud, quite simply, power and brand names. Then I slowly but surely began reading all these car audio sites, and realized that the box played a bigger role than I ever thought it did. Then I met Yuli, Don, DJ, Peter, you Les, Joell and a handful of others, who made me look like I learned everything I knew at Best Buy. If I were to really get into SPL and didn't meet you guys, I doubt I would have picked up the same testing technics and it probably would have set me back a few seasons.

The point of the vid was to use the most technical words possible to confuse people and to justify his builds when all he had to say is that he builds for sound quality and not sound pressure.
Some people just take the longest way possible to make a point.
