I have 4 Bose double Bass L1 systems, that I have used for over 2 years now.
The only problem is that certain types of music or venues like that in your face sound that a conventional speaker/horn system gives.
But since using the Bose system I have only recieved compliments on the sound, the overall balance, and the consistent sound quality in every situation.
I do sell mackie, rcf, db technologies. Unless It's a rock band or a very paticluarlly large venue, I usually go with the Bose,
If anyone would like to talk about it please email or call me.
