Set the meter for "C" weighted, Slow. For best results, set the meter on a tripod to keep reflections at a minimum. Get a Test CD that has 1/3 octave warble tones like Stereophile Test CD #3. Start with the 1 kHz tone and set the meter at 80 dB and set the 1 kHz tone to show 0 dB on the meter. I would suggest setting the meter at you listening position to see what the response is there. Start the test tones and with the chart I am suppling below, mark the level beside the frequency on the chart. You can do the corrections after you finish. Stand as far from the meter as you can when doing this so reflections off of your body does not influence the reading. Also try not to have anything else to near the meter. This will give you a close approximation of what the frequency response is of your speakers at your listening postion. Below is the correction chart. Everything is added.
