I am having a quickly heated discussion with local promoters/provider about the inappropriate deployment of head high stage stacked line arrays. Any advice when the provider asks me head on why I am backing this opinion. I would include a pic but my phone won't do it. I'm sure you can visualize the setup. 3' high stage with 4 small line array boxes all facing straight out. 30 feet back you can't see or hear the top end of the system. Talent booker is a friend and is dismayed at how bad the sound is and wants to approach those in charge and try to get a solution. Politics are involved.
