I constructed a wider baffle and did more measurements, looks better now. Near field it now looks okay. Thanks.

I will look if i can find any settings that might affect the results, thank you for trying to help me.

Okay, something is obviously wrong though. I have tested multiple tweeters and ALL of them drops significantly around 15kHz. And i know they dont behave that way "for real"

Thanks for your replies, so you think the calibration file i use is faulty? The one that miniDSP provides?

Better resolution here. Same curve.

Here it is.

Yes, 0 degrees. This measurement was nearfield, as close as i could to the tweeter. The dip is caused by the midrange being out of phase with the tweeter.

Yes, i have tried that too. Still falls too early.

Hello all! Has anybody got a clue what it is that might be wrong if my measurements always drops too early? They are never straight up too 20kHz. I have tested with many different tweeters that i know is linear to above 20kHz but in REW with calibrated Umik2 and sample set at the same (48kHz...

Thank you :-)

Hello, Thanks for your answers, my question was if the output (3,5mm) is good enough for taking measurements in REW. (SWEEPS) I will use a calibrated mic, the question was not about the mic, it was about the output and the frequency response of the output on the Macbook Pro 2015. I want to...

Hello, Sorry if this question already been posted. Is the headphone out on a Macbook pro (late 2015) okay to use for taking measurements with REW? I mean the frequency response of the 3,5mm output, is it straight from say 10Hz-20kHz or do i need an external sound card if i want correct...

Thank you! So i dont need to use the beta (v5.20)version? I can just use the latest version from the REW site?

Hello, i just signed up here :) Will the latest version of REW work with my os? I am on a macbook pro with 10.15.7 /Robert
