They already have the speaker. Its currently mounted on the backstop. They just want to move it out to the field aimed in so that the neighbors don't bitch as much. Long story.......
Turning down the PGM is not an option?
File in your "unexpected" folder": a local baseball stadium (aging AAA league facility) installed new short vertical array to cover the grandstands from the far side, maybe a 300 ft 'throw'. At the time I lived
4 blocks from the stadium and could clearly hear, at annoying level, all of the music and announcements from my back porch. Particularly noticed when it was very hot and humid from mid afternoon into evening, and those were the clues that the system designer had not compensated for the effect to propagation resulting from heat rising from the playing field and asphalt parking lots. When I visited the stadium my eyeball estimator also thought the array should have been aimed down another -10° or maybe more, to maximize coverage to all seats and not just the top rows. There's more to the story but when I talked with the designer he insisted the array was correctly aimed and ignored the convection connection. I had moved by then and don't know if anything was done to correct it.
edit ps: The take-away here is that for the most part the team wasn't complaining about SPL in the park because they could turn it up and nothing broke - but a big chunk of the radiated audio was shooting right over the West Grandstand and aimed in my general direction. Better aiming of the array would have put more PA in more seats with less energy expended outside the stadium.
