Here in Green Bay,WI my 2 double B1 systems handled a grade school Christmas concert beautifully!Setting-a 40 by 60 by 30 ft high gymnasium.A Beta 58a on the left of center and a Beta 87a on the right of center, through a Mackie CFX-12. XLR outs to Channel 1 on each system, preset 16.Grades K thru 5 singing lots of songs and one OLD Yamaha electric keyboard, and of course, a cassette deck/CD player for some accompaniment.A totally beautiful, clean, crisp sound for everything.Voices were wonderful and the kids could hear themselves as well as the audience could hear the kids!I set the towers a bit turned to the inside,on the outside edge of the stage.Compliments galore again on the sound.My compliments to BOSE again!
