PrestonTom Posted December 14, 2007 Share Posted December 14, 2007 The peaks and dips you were measuring between 25 and 200 Hz, I imagine were heavily dominated by room interactions with the speaker. At 200 Hz the wavelength is about 5 ft and at 25 Hz it is about 40 ft. Even with an MLS technique, it is still a difficult measure to do in a reflective environment. With steady-state test tones, the measures will be very difficult to interpret. -Tom Quote Link to comment Share on other sites More sharing options...
Islander Posted December 14, 2007 Share Posted December 14, 2007 The test tones were useful in letting me know where not to locate the sub. One particular spot would cause the window nearby to thrum loudly enough to give me a headache when a 30Hz tone was played, at only 90dB at the listening position, roughly 10 feet away. Reference level was 85dB at the listening position. I tried two other locations before settling for the best-sounding spot and verified it by listening to music.
