My daughter's church hired a sound engineer and they ended up with a fantastic Bose system that fills the entire church with incredibly well balanced, very high quality sound, both musical and sermons. The system consisted of 4 24 speaker L1 columns, wall mounted and I believe 2 sub woofers positioned beneath the stage area. The church seats 600 ppl and the volume was equal from all positions within the church, plus out in the hallways and entrance, even with the doors closed. The clarity was unsurpassed as was the overall sound quality.

Good luck,

Gary
