My 1st experience with the Bose L1 (not the compact) was because the piano player in the band, at the time, was told to use 2 for better sound via stereo. I also played my Synthophone through it.

My present band has the full size L1's also. My horn section is panned. Lead voice plus Bari in the center, trombone 1/2 left, tenor sax 1/2 right & trumpets full left & right. The sound is MUCH more realistic!
