I use my L1 for a few school functions in a 400 seat church, and it's soooo good, we chose to use it even for the performances when the church's built in system is available. Mind you, the audio in this church cost over $250,000 dollars. It's a good system. For our needs, the Bose does the job almost the same. (VERY serious)
Small area of difference is in the feedback area. The church's system is far more prone to squeal than my system is !

I had my first "issue" today, if you can even call it that. I did a birthday party in a finished basement that has a 7ft ceiling. The tower was too tall to fit, so I gently rocked it backwards and tilted it to face upwards. it rested nicely on the wall, I propped the bottom up, and the sound was just as good as when it is in the upright position. I'm so glad I didn't have to haul that 500lb Traynor coffin down the steps like Donny would have had too !
