"This is why a single L1 sounds like a wind up gramophone horn (With a sock stuffed in it) when used with a keyboard)

Bill, with all due respect, I don't want to get into an argument, but this is just not true. I personally set up two complete p.a. systems side by side.
One was two powered Barbettas. The other the L1. The keyboard was Tyros 2.
I a-b'd them intensely at all volumes. Two other musicians were with me. As good as the Barbettas are, the L1 sounded better and clearer. If you stand directly in front and between the Barbettas you can hear stereo effect. Get back at true listening distance and it goes away. Stand in front of one of them and you miss part of the sound because it's panned to the other side. There was no detectable degradation of the piano, or any other sound. As far as stereo "pinging" effects, you can only hear them in the optimum position anyway.
I've been using the L1 for more than two years with four or five different arrangers.
I make my living with my sound. I dumped a brand new Korg PA800 because it didn't sound good. (Yes I tried it with other p.a. systems than the L1, just in case.)
To say the L1 sounds bad with a keyboard is just uninformed. Every musician that comes in comes up to ask about the Bose, and tell me how great it sounds. They usually say something like "I wish I could afford one".
Well, I've found I can't afford not to have one. I've played small nursing homes and vast outdoor arenas with equal good results.
I just wanted to relate my personal experience with this system and take exception with such a sweeping generalization.
It seems the major critics of the L1 or usually people who do not own or use one.
Maybe they have tried one out in a store. Well when I first listened to one at Memphis Guitar Center, it sounded like absolute crap.
They didn't know how to work it, or even turn it on. They didn't even have the bass module cable engaged correctly, so it wasn't working. I left thinking how terrible the system was.
After hearing all the testimonials from people I respect, such as Uncle Dave and Gary Diamond, I ordered one with a 45-day return option, so there was no risk involved.
That was more than two years ago. The only reason I might consider parting with it is to get the updated version, as it is a few pounds lighter.
I won't be commenting more on this subject as it is all ground we've covered before, but just couldn't let that statement go unchallenged.
