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.

|
Gold Member Username: InsearchofbassPost Number: 6967 Registered: Jun-04 | pretty sure boom stick maxes out at 130 db but I heard its pretty much a piece of junk |
|
Silver Member Username: TejcurrentPost Number: 740 Registered: Apr-07 | Junk. I used one, and though it was supposed to go up to 130 it peaked at 129.2. The guy said, well thats all your hitting, so I turned the volume to < 1/2 way and still hit 129.2 lol. It wasn't accurate at all, even between a few minutes the score varied 3-4db without changing anything. Not worth the money. |
