This is the curve I tuned to. It does not look like the preference curves Olive has created. Most people would gasp if they saw this without knowing any more data. It looks bad. It came from speakers that measure exceptionally well. M5HPs.
In a real room, this measured curve sounds incredibly dynamic and realistic. So much so I can honestly say “I’m done.” I now use it to tune systems. It is dangerous to rely on single metrics as a standard of comparison. As I said, this in room response curve looks bad! Ignore the tweeter rolloff. Measuring mic/preamp issue out there.
