The EK50 L has the same great features, but double the speaker power. It has a specially designed speaker system that capable of delivering twice as much volume (*) as the EK-50
That makes no sense. Twice the power relates to only 10% more power. There is no way this new system is twice as loud, from what they're saying.
I remember that you couldn't switch a pattern while playing another one. There were also many functions that require 2 hands to activate - that's a no no in my book.
