[QUOTE="Brad Weber, post: 81504, member: 114"] Re: Small baseball stadium expansion. To expand on Art's comment, outdoors 80' is about 28dB of loss compared to a 1m distance. Say your crowd noise is 80-85dB and you want to be 6dB above that and to do so everywhere in the stands, not just on axis of the speakers. That means you might need a speaker that can output 120-127dB@1m. And that may be conservative, your crowd might be noisier or you might want to be 10 or 12dB above the crowd noise for intelligibility. A speaker that can do that, the amp required to match that, a wireless link and all the related installation (for example getting from the amp to the pole) can add up pretty quick. [/QUOTE]
