When applying "METHOD 1", it is helpful to play a jazz walking bass line (make a loop with the cd player if possible) and look for the position in the room where all notes of the double bass sound equally loud and tight.
Hi Paul - I think this is a very good suggestion. It's exactly how I make fine-tuning adjustments after general placement has been determined through measurements.
One of my favorite tracks for double bass is "Use Me" from Patricia Barber's album Companion, especially the solo in the first 30 seconds. If you can make the bass on that track sound deep, even, and fast (the most difficult), you're in very good shape.
