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?

A suggestion, I start with math for positioning my woofers (Cardas formula) which in your case will be approximately 6.25' from front wall and 3.8' from side walls. I would then start sitting (on a chair on casters) at a perfect equilateral triangle and roll back (away) from the speakers slowly which will help you find several "semi sweet" spots which you can focus on later on when fine tuning.

@lanx0003 No worries, those are suggestions. They have worked well on my 4 prior rooms and speaker setups. The most challenging were the Aerial 8b with the side firing woofers and the Betas since you have further flexibility but I had already placed a huge projection screen which can't be blocked. BTW, like the Poang but its a bit too upright for my back. |
