 Actually what is kind of unexpected is that I can get almost identical measurements / slopes with repeat readings. Even after I break things down and set up again another night. Where things go awry is when I change the output level of the AVR or on the sub - then the readings change quite a bit - that is unexpected, and leaves me wondering just what my curve really is... |
It maybe a matter of the sub/amp efficiency at low volume levels. Once the volume is high enough to drive the sub properly you get a good graph/output. It could also be a defective unit?!
