    Dear John, The screen capture in MacOS doesn't seem to work. Or that it works, but then I can't seem to paste it directly here: eg. pasting here... uploading... -progress to 100%- -error message- I was only able to post this message by taking a screenshot, saving to a file...then...

    FSAF (Fast subband adaptive filtering) measurement

    That looks good @JanRSmit This is what a virtual audio cable (bypass audio interface, bypass amplifier) can look like- If you tweak your settings (I can't recall my REW settings) you may be able to squeeze out a big more. The main downside with a 800ms impulse time, calculation may be a...

    FSAF (Fast subband adaptive filtering) measurement

    If 96Khz/192 KHz works well, but not 48Khz, I wonder if the drivers are playing up. Had you tried troubleshooting by testing 44.1Khz sampling and multiples of this? The HP filter should reduce IMD and thus get a better response in a DAC/ADC conversion. One way to tell is to use a Optical Out...

    FSAF (Fast subband adaptive filtering) measurement

    Can you please expand on this? Was it related to room / environmental noise? Or listening fatigue? Did this include drivers like your Audax or Focal? @dcibel made recordings of two drviers Dayton DA115 (alu cone, basic motor) and Wavecor WF120 (paper cone, optimised motor) and when I listened...

    Hypothesis- that H2 is that flappy rubber surround. Which may explain you may not see it in the electrical around the impedance blip of the MW16p above 1KHz, but can measure it with the microphone.

    FSAF (Fast subband adaptive filtering) measurement

    @dcibel Moving somewhere that’s less prone to hurricanes, war planes doing military drills and hotted up cars from C20 roaring down the street is in the 5 year plan. In the meantime, how can we use FSAF to see if the residual is not coming from the (rear mounted) passive radiator? The box? The...

    FSAF (Fast subband adaptive filtering) measurement

    Measuring bass is challenging, particularly with another radiator eg. port or passive radiator in close proximity with a midwoofer. Numerous methods, including near field, ground plane, or anechoic chamber all have their own challenges. Furthermore, I can hear birds singing, frogs croaking, or...

    FSAF (Fast subband adaptive filtering) measurement

    I am not looking for validation, but I am making observations based on listening to the our (limited) FSAF residual data. These findings may or may not be consistent with other designer's opinions. More than one designer has stated that "a real woofer playing is better than a 2 way +...

    FSAF (Fast subband adaptive filtering) measurement

    my quick and dirty summary (learnings so far) FSAF for measuring speakers -is highly dependent on room/environment- can vary between recording sessions (more than DAC/ADC/microphone) -The two 3-way speakers are superior to one 2-way speaker -M-noise is just punishing for 2-way speaker - I can...
