Been diggin around, and have the steps down to get a decent reference level, but I don't know where to take the SPL readings. I layed the meter in front of the sub and got wildly varying numbers depending on how close the meter was. Up close 90, where I sit won't even register(less than 50 I'd guess). I'm using pink noise from the DVD player, do I need a tone or something?
