Are these Speakers the BEST on Planet Earth ?...

They sound great are a great speaker however there are many great speakers out there.

No; use of eight 7" drivers, fail for contender as best on Earth. Not even close, and I don’t have to hear them to know that. Why? Because eight 7" drivers will not begin to produce the kind of LF that superior SOTA speakers can produce. I'm not only meaning frequency extension, but also quality, texture of the bass. These fall short of the goal on that parameter alone. Whether they are all that as regards mid/treble would have to be heard.

I have never heard them but having read a bunch of reviews especially from people who lean my way politically, they are worthy of ordering and defending In a most vociferous Manner. I may have pre confirmation bias....Or just an inflated ego... maybe both...

can I get them in Mexico Blue ?

serious, who knows..... best ????

No.
