I removed the calibration file on my OM-V2 and it works much better for now. Certainly not accurate but at least I can begin to experiment with it while waiting for the fix.
I started with Frequency response using track two sine sweep and I placed the mic in my normal sitting position. I was using two bookshelf speakers with the sub on. Two questions:
1) With each iteration of the sweep, the FR seems to jump around +-2db or so at all frequencies although more in the lower end. Is that normal?
2) I recently upgraded speakers so I decided to see the difference in FR. The attached graph show a plot of both sets. I was surprised how similar the plots are. I expected them to be about the same under the crossover (60Hz) but I expected more differences above. Do small differences translate into large differences when listening? In my listening tests, I found these two sets of speakers more similar than different for sure.
