Hi Alan,
For an outdoor space where ambient noise is high, you�ll want a speaker located about every 10 feet. Consider installing 3-4 pairs of 8" speakers. The AP840s have an 8-inch woofer cone and are an excellent choice. You could also go with several pairs of our AP660 high power patio speakers with horn-type tweeter, which is designed for commercial installations such as in busy lobbies or stadiums: speakerhttp://www.outdoorspeakerdepot.com/aphipopasp.html. Also consider installing the DSM4 speaker selector and AMP200, depending on the type of input for your wireless microphone.
