Heard a system for the second time and today had the time to walk an open field with a stage for an outdoor concert. Heard the system a few weeks ago and was underwhelmed but didn't have the opportunity to mentally measure it out. It was 3 KH4 units over 2 QSC 2x18 subs per side.
A picture came into my mind after a few laps around the listening area. The overall tone of the system changed every few feet. Unlike a horizontal trap array...which I have used in this same space many times, where it gets louder as you get closer but since you are in the same box pattern, the tone doesn't change much..as you walk towards the Karray speakers everything fluctuates with every few steps. Everything from 200-700 seemed to ebb and flow as I walked towards the array. The high end sounded like a big Bose L1. Very rolled off and not dynamic. Horizontally I noticed a big lack of any kind of stereo imaging. There was a spot I could stand where the vocals were in both speakers...to my ears...and if I took 1 step to the right...the vocals completely shifted to the right speaker and I had no apparent level from the left. Furthermore... This same one step 'shift' held true to almost 200 feet out!! So if you were off center by even a few feet...the music and vocals appeared to come out of the speakers and not from the stage.
I am going to a Karray demo on Thursday to hear new models. I will post my impressions.
