So, now I tried measuring the sub.. I got this graph:

It looks like it's jumping very much up and down.. could this be the right graph, or do you think I got something wrong with the measurements? If you think it's the real stuff, what would you propose me to try changing?
I can recognize the 45 hz peak, which I hear very clearly when I make the 100hz LFE sweep from the AVIA dvd, so that would indicate it's the real curve i get...
I think I will try make a measurement with the sub on some different locations.
And btw, would it be ok just to unplug one of the main speakers? (Since the output on the soundcard is only connected to L or R on the receiver) That would save some time since the cables I use is quite annoying to work with
