Here's the charts showing the results of the Audyssey MultEQ Pro calibration of Jay's speakers. The black is the "before" and the red is "after." Notice:
1. There is a steep high-frequency roll-off.
2. There is dip at around 2 kHz - that's the so-called BBC dip. It's purposely applied.
3. The frequency response of the subwoofers (2 x SVS Ultra 13's) is incredibly flat both before and after. That's because the subs were pre-calibrated with an SVS AS-EQ1.
