Hello REW Experts,
I am using UMIK-1 for my JBL L5 speakers trying to perform room correction.
I am confused why the filters that are generated are excluding the entire mid range?

The main issue looks to be the target shape. The target is a full range speaker rolling off at 35 Hz, but the response doesn't roll off. That means the target match ends up trying to use EQ filters to produce a high pass response, which they are not at all suited for.

If you change the target to None it should work OK.

why does the measurements from REW look different from measurements from Math Audio?
REW shoes this dip around 53 Hz which MathAudio did not capture. Not sure why.

My guess would be that MathAudio is applying some kind of smoothing to the signal...
What happens if you click the High Resolution radio button in MathAudio...
Or try 1/3 smoothing in REW...

PS... Please post .mdat files as requested...
