With all the budget cuts we've had, our school is really going cheap on prom this year, and as a junior class, we are organizing everything for the prom. To help cut costs, one of the things we are doing is instead of hiring a DJ, we are going to make a playlist of music everyone likes and running it through some speakers. We are going to be in a fairly large ballroom (UNI Slife Ballroom), and I have NO idea what size amps and speakers I need. It needs to be loud (this is a high school dance, remember) and it needs to not sound like crap. There is a 1-day rental of a 800 Watt 12-15" PA system for $150, but I have no idea if that is a rip-off or if we need more or less than that. Basically, I know how to plug stuff in, but I'm not enough of an audiophile to know how much power we need. I'd give you the specifications for the room, but I can't find any. Thanks!
