Back yard projector and Screen...
I was actually looking at doing this myself. In general, not specifically for the super bowl. My backyard is a 50'x50' with 6' high concrete walls.
12 foot screen (12ft across).
Short throw lens on a projector mounted 10ft away.
3 speakers for LCR.
4 rock speakers for surround.
Anyways,
What does your backyard look like?
Do you have to worry about any kind of reflection's?
What are you doing to contain the sound, as to not annoy your neighbors?
Because it is a open area, is your audio quality going to sound bad?
