    I've just read a thread about setting subwoofer position and levels using various tones http://www.avforums.com/forums/showthread.php?s=&threadid=33958

    Im getting confused here...I have set all my speakers to 75db using the spl meter..The sub i lowered by about 6db as i found it too loud (also advised that the spl meter doesn't read bass very well and to lower the 75db setting of the subwoofer by about 7db)

    What exactly are the downloadable mp3 test tones for ?

    cheers

    The test tones are to see what sort of response you´re getting from the subwoofer.

    Initially set all your speakers to 75db. Put the sound meter where your head would be at the listening position, set the meter to 70db C-Weighting Slow. Then use the internal test tones (or Test disc if you have it) and balance all the channels to 75db including the subwoofer (feel free to lower or higher this by a few db to your personal taste, mines at 76/77db).

    All my speakers are set to Small and all the bass is sent to the sub.

    Once done you can then use the MP3 tones to get readings (like you´ve done) and then its a case of playing around with positioning to get as flat as response as possible.
