A half-dozen KJs and at least one DJ in my part of the world switched to the L1 during the past two years and every one of them said they would never go back to a conventional sound system. And, they're all using a single L1 with a single sub cabinet.
One of the KJs came to a place where I was playig a happy hour last week just to hear the system. When I finished playing he quizzed me about settng up the volumes, which must be done exactly as the manual states or you will not be happy with the sound. After showing him how this was done he admitted that he didn't read the manual--just plugged everything in and turned up the volumes. He said he was happy with the sound, but had some distortion at higher levels. He called a few days later to thank me for showing him how to set the system up and that everything sounds fantastic now.
Diki, I don't hear a hole and lower mid-range sounds, but I'm old and my hearing is shot to hell. And, when playing and singing I would think it would be nearly impossible for the performer to hear any deficit in sound if it did exist. As it has been stated many times, there is no "One Size Fits All" sound system--it does not exist. However, for me, the L1 is about as close as it gets.
Good luck,
Gary
