Editing Your Curves - Midrange Compensation
I had to lookup the Internet to discover what this option does:
Midrange compensation is an intentional dip in the 2 kHz region where the vast majority of tweeter-to-midrange crossovers are. In that region the tweeter is at the low end of its range and the midrange at the high end of its range and the directivity of the speaker goes through major changes. We found that if that region is equalized to flat, the change in direct to reflected ratio that happens because of the directivity variations causes voices to sound harsh (among other things). So, we have this implemented in the Audyssey target curve. With MultEQ Pro you can choose to turn it off, but we don’t recommend it. This notion was observed 40 years ago by BBC speaker designers in their studio monitors. They designed their speakers with this “BBC dip” intentionally in the speaker response.
Turn this option off for the speaker will disable the 2 kHz dip from the previous page. i.e. you are getting a flat response all the way to around 14 kHz before rolling off. You can verify this is happening by looking at the ‘Target Sound Options (the 2 kHz dip should be gone if this if off).
So what should you do here? Try turning off the ‘Midrange Compensation’ and listen for a few days.
If you notice a lot of harsh noises, or when the sound gets uncomfortable for your ears, it means your system requires the 2 kHz dip. Pay extra attention to any words or noises that sounds like ‘S’ or ‘SSSH’. If it’s a problem, go back here and turn ‘Midrange Compensation’ back on.

The hints how to copy and rename curves helped me a lot. Unfortunately the app is often not self-explanatory. Many thanks for your work.

A big THANK YOU for your article! This is what the user manual should have been! I followed it all the way through and successfully made the measurements, edit the curves, and uploaded to the receiver (Marantz AVR7012) , all in the First Try! However, the second try did not go so well. The app kept losing the receiver and I had to start over several times…… That’s probably is one of the reasons for low ratings. I finally noted your suggestion and use the IP address to "help" the app find the receiver. All my equipments are on a wired network, and the tablet was less than 5 feet away from the router. Never had any connection problem on wi-fi . Yes, the app is great , if it’s consistent. My cons are:
- Occasional loss of contact with receiver… "may" be handled by giving it the IP address to search on retry.
- Slow. It took me about an hour to upload the data to the receiver (AVR 7013 and Galaxy TAB-A). Many times I thought it was hung, but just waited it out.
Many thanks again for a very helpful article.
