Why should it be aimed 45 degree (into the ceiling?) Wouldn't the off axis response cause the result to be more inaccurate?

Also, I would assume that the meter would have to be aimed at the speaker that is producing the sound, the 120+ deg off axis response for the ratshack mike would be terrible for the high freq portion of the pink noise. Any explaination for your method?

I also disagree on the method of setting up subwoofer level, since most method is to use pink noise to match at 75 or 85dB. If the subs are not placed in the proper location, serious peaks and/or nulls would occur, and if there are a couple of serious peaks w/o any significant nulls, the sub level would be set too low, resulting in a uneven transition from the speaker to sub around the crossover freq. I personally prefer to match the -3dB/-6dB level @ xo freq of the main/sub.
