Your room doesn't look that bad to me, many are much worse. Of interest is that you mapped out the "golden triangle" and then didn't adhere to it. As others have suggested, your listening chair is too far away from your speakers. I suggest you pull your speakers another foot into the room and move your seating position at least two feet farther into the room. Try listening to music instead of measurements.
What happened to my room acoustics
I measured the spectrogram for my room at my MLP, and the FFT results are as follows:
- There is a roll-off before 20kHz.
- A dip is present around 12kHz.
- There is a noticeable boost between 50Hz and 1.5kHz.
- The bass rolls off around 33Hz at -3dB, consistent with the factory rating.
Comparing these measurements to the Burchardt measurements, there are some differences:
- It doesn’t exhibit a roll-off before 20kHz.
- The dip is around 15kHz.
- The boost between 50Hz and 1.5kHz is not as pronounced as in my room.
I’m curious about what might be happening with my room acoustics. If a fix is possible, what would it entail?
