Although I've never had the chance to hear the LD systems I did get to do a good tryout of the JBL EON One and came away totally impressed. Big full range sound and much louder than the system size would indicate. Best part is the easy setup / packup and moving of the system. One 40 lb piece with a balanced handle on the top.
I wish I was working more and had an excuse to buy a pair. Price is good at around $700 down from MSRP of $999.
