    Ok I have my SVS dual 39+/s1000 combo and I calibrated everything to 75 dB's except for the subs...they are at 80. I also ran some test tones that I have burned onto a CD so I can see my "room curve" and if I would benefit from and EQ. I have no idea what I am doing so please be gentile on me [​IMG]
    Ok I don't know if I went over board but I went from 10hz to 100 Hz in 2 Hz increments. I didn't use any of the correction values because I didn't used the exact numbers from the SVS sight and I don't know how to figure them out.
    So here are the actual #'s I got in the listen position with my RS meter pointing up about 45 degrees above the center channel
    Hz dB's
    10 54
    12 60
    14 67
    16 74
    18 82
    20 88
    22 89
    24 91
    26 93
    28 87
    30 84
    32 81
    34 79
    36 77
    38 78
    40 77
    42 76
    44 72
    46 72
    48 70
    50 70
    52 72
    54 73
    56 72
    58 71
    60 71
    62 72
    64 73
    66 72
    68 72
    70 72
    72 72
    74 74
    76 76
    78 76
    80 76
    82 75
    84 74
    86 73
    88 65
    90 67
    92 71
    94 72
    96 72
    98 69
    100 69
    200 78
    500 72
    I saw someone with these last 2...I don't know why, but I did it any way. So what's next...can someone help me do the correction values and tell me what program I can use to get a graph.
    I can let you know any other info you might need and I can get pics to. Or I can do it over with less numbers [​IMG]
    Thanks every one

    I am no expert, I'm still playing around so I can't help you with the techie stuff but I can steer you to this: http://www.snapbug.ws/bfd.htm this is a BFD site and is a really good site. Down a little bit on the 1st page is the "excel" link for the graphing tool.
    Hope that helps a little,
    Matt

    Yeah I think I might cut down on some of the numbers and just use the ones listed on that guys chart.

    Thanks

    Mark

    Do I need to cut down on the numbers or can I use them????

    Hi Mark,

    Go ahead and apply the correction factors you and I talked about in email. Then try to tame the most severe peaks to start. See how far these 2 steps get us...
