How do you folks use your Radio Shack SPL meter when you are calibrating your speakers? Do you:

1. Aim the meter at each speaker?

2. Just point it to the front and make all measurements from that single postition?

3. Point the tip of it vertical and make all measurements?

Just for reference, the instruction manual says to aim it at each sound source.

I'm just curious.
