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...

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...

This driver? https://media.focal-naim.com/dam/ps-130-fe/ft_ps130fe.pdf

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.

@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...

I was going to take some in-the-middle-of-night trax for Mike. But then...

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...

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 +...

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...

Sure am glad this forum had editable features. FSAF has forensic level of recording. ESS vs FSAF + IBS, Winner winner chicken dinner!

Here's another driver, this time I'm going to let it run "full range" ie. without any filters. The equivalent Sweep... Any errors or (mis)representations is the author's own fault. (small office sized room of 3.6x3.2mx2.4) Listen at your own risk!

Part of my curiosity in FSAF was to see how a speaker might sound using the FSAF residual), as opposed to how it might appear appear (harmonics, IMD etc), and is there a relationship/correlation? Essentially, FSAF would be a suitable method of hearing how it may sound (residual). However, it's...

Whether I use the measurement Sweep, or FSAF, using a file-saved ESS stimulus, or a FSAF with ESS stimulus, this time saved at +20dB louder than the previous setting- I get the same frequency response: Looking at the noise floors shows something very different between the three: If the...

@dcibel Should we be saving a Measurement sweep at -12dBFS? When we make a FSAF measurement with that sweep, would it go through another pre-gain stage? Suppose that I've have my system calibration such that -20dBFS gives me 2.83V at the speaker terminals... Compare your headroom on your...
