I'm not convinced that the 40k glitch is real. At the very least, I would rerun the measurement to confirm. Unless the original was a 24/96, it is not in the original. It is possible that this driver has a 2X resonance above the date, but again, it needs to be confirmed.

I think all this is 40kHz talk stemmed from Jay (post 255) saying that:

"it was a common practice, in recording studios, to use high Q >=40Khz bell filters to bring more air to some female voices, while nobody is able to hear such a frequency, neither most of the speakers to reproduce them..."

There is no 40kHz glitch in data presented here.

The source material was not 24 bit 96kHz, but the recording that I made was at 24 bit and 96kHz, processed to 320kbit mp3 stream with 48kHz sampling.

As I figured. The glitch is a processing error in REW. Most likely a one-time event. I do realize that downward sidebands are important. My hearing is pretty well gone by 12k now, but I can hear when the 15-20k stuff is beating down below 10k.

What glitch in REW are you talking about? The 20kHz razor edge ridge in the CSD of the P830986?

That is a real ring - not a glitch. Glitches have wider spectral widths - not a sharp resonance.

I suppose that it is time to mention that I picked the A7.3. Really. I was using a pair of ear buds rather than my stereo that uses A7.3 on top of RSS315HF-4's. It just happens to be the sound I like. I thought that the A7.3 did a better job on cymbals.

IMO listening to mono clips gives only the vaguest hint of what a stereo pair will sound like. When I started the test, I added the "original" to the play list. I thought that all of the clips sounded like crap compared to the original. Then I realized that I had forgotten to downsample the original to mono. Once I did that, the original sounded like crap too. Then I could proceed with the test.

Something to note about most "full-range" drivers. Most, not all, will show a peak in the sibilance range that is the main cone break-up. Most, not all, "full-rangers" need a notch filler to remove or at least soften this peak. Fostex, Lowther, most Tang Band's sound seriously better with a notch filter.

I use just the right channel of the source - not mixing it down. Sometimes the right track is missing essential content - but I did not want to add an analog multi channel mixer mono converter to the pot. If I put everything on computer as source then easy in Audacity when playing back. I find tracks compressed to mono sound funny.

Eh, was it only me that heard the weird break up of Norah Jones voice at the end of clip G???? I.e. A7,3.
This was heard through my Grado, Sony earbuds and Genelec Monitors….

Sorry never got to end of track because its so hot for all three listening tracks and judged it to be impossible ranked top three in my taste and put it aside. Same was for P830986 and before xrk971 revealed what driver belongs to what letter i had those two transposed in what driver i believed was listening to.
Can we say it suffered recording microphone is sitting on axis and it in reality have a voiced house curve not easy to see reflected in datasheet that is very hot in some frequency areas but in reality sounds nice off axis with its own signature EQ/DSP or not, and for owners this driver seems natural never listen on axis then it shine.

Nej Byrtt;o)
This/these peak/s in Perless driver is not troubling me and a lot of others obviously. If it's hot for you, fine. Let's call it a day then😱)

The break up I'm writing about is much lower in around 1.0-2.0kHz, I guess??
Hmm, I have to look up the German magazines I have at home. I have a nagging remembrance of measured high distortion in this area of the metal cones of MA Audio. But I could be talking out of my pie hole for sure….

The A7.3 does have a higher than average distortion peak around 1.5kHz. I wonder if that is what you are hearing?

You are welcome. What are your impressions of the CSD?
Click to expand...

I am not accustomed to see CSD monochromatic plots. I found the thumbnails easier to compare. The CSDs confirm what we already know about the objective qualities of the drivers, and harmonic distortion plots even more.

Note that in round #1, I vote for driver B (29.5% ) and then for driver F (6%), the first and the last in the classification. I detected some coloration in driver F but I nevertheless found its the sound pleasing.

Now I wonder how the ScanSpeak 10f/8424G would compare with the
Visaton B80 (not available in USA, I think) which has almost the same emitting area.

It's I believe just a microphone handling or something when "stopping" the recording. It is not the driver fault.

BTW, I feel like A was the first one recorded, then G the last one. H was added sometimes later, or between A and G.
