Had the Bose L1 (2nd generation) system on trial last night - quality of sound and projection was just fantastic. The only concern was for the system to be heard to the back of the hall. required a high volume level for the musicians on stage - can this system be paced beside the band or slightly in front to allow for plently of sound out front, but still ley the musicians hear what's going on without monitors - we had no issue with feedback and were really impressed with the quaility.
