I have audited the GR tower and it has some sonic semblance to the irs that used to be set up at the ps audio factory. I felt the ps audio room was too small for the irs, however. If you are sitting farfield, the room comes way more in play as well.
The weak link in Danny’s rig is not the speaker, imo, but, the dinky caliber electronics Danny tends to use. It almost felt like he either didn’t know that...a certain caliber of electronics existed or didn’t care (i didn’t say it explicitly to his face to upset him, of course). Jay, on the other hand is probably used to a heavy hitting/meatheaded front-end.
Open baffle bass can also throw some people off for a minute.
It would be interesting to see Jay trial that tower in his room with his front-end.
You can get an excellent DIY system for MUCH less money that plays plenty loud without looking like overpowering skyskrapers and probably sounds better being played at volume matched to the room size.
