Actual curve always strange, Room fit

[gammeljohan]

Hello!

When doing room fit (with microphone on Pixel 8 PRO) it always shows a very strange curve when checking the results. What's most prominent is the lack of base according to the curve, but it's not The case when actually listening. I've tried with an IPhone as well, but it's The same thing.

Any thoughts what's the deal?
Thanks!

The high frequency peak is caused by the built-in mic's characteristic.

The broad dip around 80.Hz is probably real, but could be caused by various reasons. Just for testing you could try crossover frequencies of e.g. 150 Hz and 50 Hz and perform the same measurements again.

Wow all the way from 50-100Hz! That's the Grand Canyon of nulls!
