How do I point my speakers for maximum effectiveness?

Depends on what you are trying to achieve, the amount of gain before feedback that you need, etc. The dispersionangle is not fixed for all frequencies. For a "90 degree" box, typically it will be close to 180 degrees from 4-500Hz on down. As you get up above about 6k the pattern will start to narrow depending on the geometry of the horn.

Well its going to be a pseudo outdoor show. We're playing in a barn with about 20sq. ft of room inside the barn for a crowd and the rest will have to be outside, past a door ( open of course ).

 

This is our first time playing out our PA system so we're not exactly sure what we need. We do need a bit of gain before feedback, as we are a pretty loud band and our vocalist can be kind of weak.

 

Thank you for the advice!

Then your top diagram will be more successful. This helps with "wraparound" of lower and midrange frequencies.

Thanks!
