JBL everest?

They’re in the ‘old school’ JBL camp, designed by Greg Timbers who did a number of iconic big JBL designs over the years.  

I havent had a chance to hear them, but I’d like to.  

From on my understanding the ‘new school’ JBL pro designs measure and perform better on all of the quantitative data, with the JBL M2s having all of the SPL capability of the Everest but with smoother on and off-axis response and deeper bass extension, all for considerably less money (even including the required Crown DSP amps). 

The Everests sure look pretty though.  

Horn speakers, like some JBL's,  are a good match with valve amps because of their higher sensitivity, however for smaller rooms, horns can sound harsch when you'r sitting close to them. So my opinion: those big JBL's only if you have a living room  the size of a ballroom. Horns are mostly applied in PA speakers, where sensitivity is more important. 

Make that: "Horn speakers, like some JBL's, are a good match with QUIET valve amps"... 
I tried to match Klipsch La Scalla II with PrimaLuna integrated and got nasty transformer hum which I could hear 12 feet away.
Lost many hundreds of dollars on that deal. 

The good people at VPI have one of the large pairs of JBL's as their reference speakers

JBL is relaunching the L100 this spring.  We'll see what that does at $4K a pair.
