I was thinking it might be fun to host music nights in my local park. Basic idea, I built two or more really good speakers, large enough for an audience of perhaps 40 people on picnic blankets, then we listen to music for two hours.
The speaker design and layout is another discussion altogether, but I was wondering, realistically, what kind of battery system I would need to do this for, say, two hours.
I am assuming I'd be using relatively high efficiency speakers, probably with active or at least hybrid crossovers. Loud, live level bass is not an objective, I'm not trying to create an all night rave scenario. I am not a bass expert but I assume some kind of bass horn would be the way to go for this system. Amplification would be class d of some kind; I assume some drivecore amps or something like that but minimalism is another goal.
Other than amplification, source would be some kind of digital player and of course dsp.
So, anyone willing to do some back of the envelope calculations to see what wattage and how many watt hours I need?
