The mains delay (~6ms) can be seen in the phase trace. The phase starts to diverge at the crossover area starting around 100Hz (XO=85Hz LR4). Any comment about the step response shape/behavior? Happy to hear your views. /

Just in case you need the mdat file, it's attached here. Thank you very much in advance for your comments and suggestions.

Hi folks, Seeking feedback and comments from the general community about these 2 step responses. Setup: 3-way monitors with 1 subwoofer Crossover, room correction, delay are implemented via FIR filter. Crossover & room correction is identical. One has no delay, the other has delay on the...

Got it. Thank you.

I was reading up about FSAF. https://www.avnirvana.com/threads/fsaf-fast-subband-adaptive-filtering-measurement.13810/page-2 I downloaded "FSAF 2.mdat" from post#27, opened in REW v5.31.3, clicked the "Distortion" tab, REW crashed. The other tabs seem fine, only the "Distortion" tab would...

Hi folks, I could not get REW v5.31.3 to work nice with the new Steinberg generic ASIO driver control panel. Ref: https://helpcenter.steinberg.de/hc/en-us/articles/17863730844946-Steinberg-built-in-ASIO-Driver-information-download I want to choose different device to use, therefore in REW...

I updated to 5.31.3, yes confirm fixed. Thank you very much. :)

I was playing around with EQ on a graph and REW crashed. Below is the crash report. REW V5.31.2 running Azul Systems, Inc. JRE 1.8.0_412 64-bit on Windows 10 Locale: language en, keyboard US, windows-1252 at 96 DPI Running in C:\Program Files\REW Message: java.lang.ClassCastException...

Thank you very much for sharing your insights. Much appreciated.

What is a reasonable time delay between woofer vs. subwoofer?

I redid the measurements, keeping everything constant except for subwoofer delays. The main speaker is a 3-way active, and single subwoofer. The chart looks like this: ^ the red one has subwoofer delay of 5ms added in the digital crossover configuration. I have marked out the various peaks...

Okay, so the vertical axis isn't that important I guess, since the peak is locked to 100%, everything else is scaled/displayed relative to the 100% peak.

Dear all, I would be grateful if someone can shed some light why a step response so called "starting point" or "zero point" can be so far below zero. Refer to the attached image. Any feedback would be appreciated. Thank you very much.

My condolences to you, John, and your family.

I was playing around with RTA settings and hit this error. Not sure what I was doing to cause it...
