 The impulse plot looks entirely normal for a subwoofer, nothing to be concerned about. Distortion shows up as scaled-down images of the main response further to the left of the main peak, the longer the sweep the further to the left they are pushed. |
So, the fact that the first graph's full range sweep of the CBM-170 has a rather long rise toward the actual impulse (far more than the -125 ms left IR window) be of no concern?
If not, and it's not really distortion, any idea what it is? Another room issue?
Also, should I increase the left (and right) IR window to where the noise starts (-500 ms, and ~900 ms respectively) to capture this energy information?
Thanks for the help!!
