I have heard the JBL Everest speakers at RMAF years ago...Large room.. I can't remember the amplifiction....They sounded transparent but not very musical to me...I love JBLs from the 1960s and the Everest had some of that same sound flavor, just didn't move me. At the same or lower price point, there are so many great choices ...heck, in the $1000-$15,000 range there are so many good choices of speakers that may have kept the big JBLs from getting much play in the US/EU...At the over 50K price point there are many other contenders.... Such a cool thing about hifi....truly something for everyone at most any price point..
