That's not a wall of sound. Now this, this is a Wall of Sound. #wallofsound

26.400W of McIntosh power is nothing to sneeze at. #wallofsound

Er, think that might be 26,400W... Unless you are one of them foreign-types that seems to swaps "," and "." in numbers just to confuse me. #wallofsound

C'mon man, value mattered to Dead. Value as in the experience delivered to the fans that toured with them. You don't think it was the client that demanded that set up? #wallofsound

But you think it's "the world's dumbest sound system." If I understand right, you would have made it smaller and quieter because you think that is value. But then--correct me if I'm wrong--the Dead wouldn't have had the largest sound system ever built, would they? If I'm recalling correctly that SPLs drop off as d squared, your proposal to halve the power would mean that it would have good audio quality at only 150 feet (instead of 600) and acceptable quality at 330 feet (instead of 1/4 mi.)? That is "smarter" exactly how?
Bottom line, I can criticize a Shelby Cobra and say they could get at least half the speed with a four cylinder engine instead of a V8. But what is the point? It sure as heck doesn't make me better than Carroll Shelby as a car designer. The egotism of believing that your understanding of "value" should be universal is pretty appalling. #wallofsound

While you’re at it, you might want to avoid wikimath calcs, they don’t become you. In free-field radiation of energy (sound or otherwise), the inverse square law applies to the pressure, power or intensity in linear units. SPL is in dB so your math is completely wrong. If 600 ft was the cutoff radius for acceptable coverage level (which btw is a misinterpretation of the wiki article…see below) then cutting 3 dB would reduce it to about 426 ft, not 150.
But all of that is rather irrelevant to the idea of "good audio quality". Level is hardly the only aspect of "good audio quality" though you seem to interpret that as being 100% correlated to level. But certainly level is important, which is why no one designs nearly omni-directional sound systems like this one. You can make up for lost level by increasing directivity (and yes, horn-loaded drivers did exist 35 years ago). Yes there are tradeoffs to everything in audio, maybe the near-field fidelity would not have been as pure. But then again, how much do you think the fans cared about the fidelity when the tour was canceled due to the logistical nightmare of the WoS.
Finally, your comparison to cutting speed in half just further demonstrates your ignorance in relation to audio. My point was that cutting the system in half would not even come close to cutting the performance in half…and as I have further indicated, you could make up for the lost level with very common audio design principles. The WoS was indeed application of pure power ignoring other design principles. It is the "more cowbell" approach to audio which results in ridiculously large and overpriced systems which could be engineered to be just as effective at a fraction of the cost. But if you find my opinion too appalling to stomach, you can just go ahead and let this thread die, I doubt anyone else is reading at this point anyway.

It's always entertaining to see someone make a ridiculous stupid statement ("world's dumbest sound system") and then tie themselves in knots trying to justify it. #wallofsound

And for $4,500 it sure as hell better at least kill that bitch dog Fluffy McMuffinator across the street whose 80 year-old owner lets it crap on my doorstep every morning.

Doc Brown: "My equipment... That reminds me, Marty. You better not hook up to the amplifier. There's a slight possibility of overload."
Marty: "Yeah, I'll... I'll uh.. keep that in mind." #wallofsound
