I am very familiar with the Eon as a stage monitor and FOH PA. The ridiculous max SPL of the system (1000 watts behind 15" woofers, IIRC) is impressive, but....
I'd guess that it would be a very bad solution for amplifying solo piano. It's all punch and bark - a rock band will sound like a rock band - but it sure ain't designed with piano in mind. I suppose that, in a rock band setting - with much of the the left hand passed off to the bass player - it might work okay, but for solo piano, I personally wouldn't go there. Just the wrong tool for the job, IMO.
