Hi John,
I’ve been using the JBL Eon 15’s with my Technics keyboards for about seven years. They have proven to be bullet proof. They weigh 40 lbs. each, and along with the 7K and a mixer it is just like getting a workout at the gym. However the sound is beautiful. I’m fond of strings and woodwinds. They are as smooth as silk, without the harsh character that many sound reinforcement speakers have. JBL has always had a reputation for a rich but undistorted mid range and it is still true of the Eon’s. The bottom end is strong but not boomy. My pal Scott Yee gave them the golden ear test recently and seemed to be impressed with the speakers and the capability of the KN7000.
