New set of graphs for all speakers reviews

[sweetchaos]

Glad to see you were able to use this data and add it to your database!

Errata:
1. I didn't see that you already had the Kef Reference 5, my mistake. Did one extra, haha.
2. I think you've missed adding Erin's Neumi BS5 to your database, which I've digitized yesterday.

Improvements:
- Separated dropbox data, by sources first (Archimago, Erin, Vendor, etc)
- Digitized 9 (all available) of Archimago's Musings (quasi-anechoic spins)
- Digitized 5 of Audioholics data

To do:
- Audioholics, 23 more to go
- SpeakerData2034, lots more

I would definitely feel a lot more comfortable with it if pierre took your suggestion of differentiating the measurement type, e.g. anechoic, NFS, quasi-anechoic =]

That's underway.

my fault, I mixed the 2 reviews from Hardis (with and without the P at the end).

Improvements:
- Separated dropbox data, by sources first (Archimago, Erin, Vendor, etc)
- Digitized 9 (all available) of Archimago's Musings (quasi-anechoic spins)
- Digitized 5 of Audioholics data

I will add them ASAP.[/QUOTE]

 

[sweetchaos]

Done:
-Finished digitizing all of Audioholics' spins (23 more, 28 in total).

To do:
-SpeakerData2034 (81 more spins, lol)

 

[sweetchaos]

Another bug...looks similar to previously reported one?

when you select 'vendors' and 'revel':

And look for 'vendors-revel' links, you'll see 5 Revel models.

But in reality, when you just select 'revel':

And look for 'vendors-revel' links, you'll see 9 Revel models.

 

[sweetchaos]

Small mistakes:
1. IK Multimedia MTM link shows "iLoud Micro", not MTM.

Spoiler

2. JTR Noesis 212RT doesnt have a source link.
Here it is. It was measured by Matthew Poes (from Audioholics), not by Vendor.

3. In your 'scores' page, it's written as 'Preference Scores from Harmann'. Harmann should be spelled as 'Harman'.
https://www.harman.com/

Areas for improvement:
1. Please indicate whether a link to a graph is now outdated/obsolete on the page OR alternatively, remove any outdated/obsolete graphs.
Example 1:
v1: https://pierreaubert.github.io/spinorama/Infinity R253/ASR/index_asr-v1-20201126.html
v2: https://pierreaubert.github.io/spinorama/Infinity R253/ASR/index_asr-v2-20201202.html
Amir, since publishing his original spinorama (v1), has updated his article and is only showing the latest spin (v2) now.
In other words, showing v1 is meaningless, as the v1 was done using a faulty microphone, since he wrote:
"EDIT: something had gone wrong physically with my measurement mic in the original review. The cap on it had come loose and then proceeded to rotate 45 degrees, hanging by a thread! It was not that way when I started the measurements but somehow ended there. That changed the high frequency resonances of the mic, resulting in peaking that we had. I have remeasured the speaker and edited the data in this review now."
Example 2:
v1: https://pierreaubert.github.io/spinorama/Revel F35/ASR/index_asr-v1-20200315.html
v2: https://pierreaubert.github.io/spinorama/Revel F35/ASR/index_asr-v2-20210415.html
I'm saying it would be nice to see right away whether the graph is obsolete/outdated just by looking at this page (which of course it is obsolete in that link).

2. Perhaps I didn't see it mentioned, but what differentiates towers from bookshelves? I see a few bookshelf speakers that are currently labelled as towers. A simple definition would suffice.

Just trying to improve your project by 1000%.

Mistake:
Website says "Revel Ultima Salon", and the corresponding spinorama is correct, but the picture shown is not for the "Ultima Salon" but instead the "Ultima Studio".

It should be this picture of "Ultima Salon"

Here are the spins and photos of each speaker.

Improvements:
- Added 24 more spins from SpeakerData2034

 

[sweetchaos]

Feature request:
-Please add the ability to select the type of data on the main site, in a drop-down menu....once you classify each spinorama in terms of raw/digitized, or NFS/anechoic. This way, you can quickly filter models based on how accurate their spinorama data is...NFS and raw data being most accurate.

Improvements:
- Digitized 29 more spins from SpeakerData2034

Left out:
-SpeakerData2034's Revel In-ceiling (14 spins) and Revel In-wall (14 spins). I'm not sure if there's any interest in digitizing these? I don't have the will to import these 28 right now.

Number of spins I've imported so far:
9 from Archimago
28 from Audioholics
5 from Erins Audio Corner
58 from SpeakerData2034
4 from Vendors
--------------------
104 in total.

That only took 5 days to complete...

I am slowly catching up.
- ErinsAudio Corner done
- Archimago
- mostly working
- data is not working for the edifier, i think webplotdigitizer is confused by the 2 ranges
I will do one a day or so.

Noted. I'll separate the two graphs, next time I'll digitize Archimago graphs.

Improvements:
- Digitized all 19 spins, measured by @napilopez
- Digitized Magnepan LRS, measured by AudioXpress (paid audio magazine)

Or 124 in total since I started.

Have a spinorama graph that you want me to digitize? Let me know.

You don't need to do the ERDI and SPDI curves btw if the graphs have the other ones. Software computes them from the others.
The reverse is not implemented and could be useful if the graphs are unclear which happens when ON overlap too much with ER for ex.

So, are you comparing the digitized ERDI/SPDI vs the computed ERDI/SPDI? Or are you simply computing them, and I've been digitizing them for nothing? lol

I would definitely feel a lot more comfortable with it if pierre took your suggestion of differentiating the measurement type, e.g. anechoic, NFS, quasi-anechoic =]

People down the line won't know the full history of the measurements or necessarily be following closely the events of this forum to know how the measurements were taken and potential limitations.

In any case, I'll be including the spin curves from here on out. I'll consider doing individual angles too.

Hello,

I am tagging measurements. What are the relevant categories for quality of measurements? So far I have:

Klippel -> Anechoic -> Quasi Anechoic -> Unknown

from best to worst. Does that sound reasonable?

 

[flipflop]

I don't mean to be pedantic, but I want to remind everyone that Klippel NFS data is anechoic. What's being referred to as 'anechoic' in this thread are anechoic chambers, which are not fully anechoic in the entire bass range.

I suggest that the quality rankings look like this:
Klippel NFS > Anechoic chamber > Quasi-anechoic > Unknown > Vendor

vendor esp. HarMann are using an anechoic room. Also the amount of smoothing on the data is also important. It could be measured on an NFS and smooothed 1/3 octave.

 

[Astrozombie]

Even an anechoic chamber isn't actually anechoic, jjeeez i have a headache.

hello @sweetchaos,
instead of doing the import one by one I build a script. I messed it up and I did many by hand corrections.
I am sure there are many errors. I have implemented various suggestions from the 10 or so previous point.

 

[sweetchaos]

Improvements:
- Digitized Audioholics' JBL L100 Classic (12" woofer)

Note: napilopez previously measured the JBL L82 Classic (8" woofer), so it's great that we have both measurements.

Feedback for pierre:
I looked through your imported graphs in more details to spot any mistakes...

Graph is screwed up:
1. Edifier S2000 Mk III (graphs completely out of place)
2. Fluance Reference XL8S (graphs completely out of place)
3. Polk L800 (graphs completely out of place)
4. Neumann KH 80 (missing lower frequency extension)
5. Buchardt Audio S300 (squished for some reason)
6. Elac Debut 2.0 A4.2 (no graph shown)
7. JBL LSR308 (no ERD or SPD)

Completely missing spinorama for:
1. JBL L82 Classic, napilopez
2. JBL HDI-1600, speakerdata2034
3. JBL HDI-3600, speakerdata2034
4. Revel M126Be, speakerdata2034

Wrong name:
1. Bower Wilkins WM7.5, name should be "Bowers & Wilkins WM7.5", to match the other Bowers & Wilkins speakers. Also, this is not a bookshelf, but an in-wall speaker.

 

[sweetchaos]

Also, why have the same olive score for the same speaker, but they were measured by different people?

1. Measured by ASR
https://pierreaubert.github.io/spinorama/KEF R3/ASR/index_asr.html

2. Measured by Erin
https://pierreaubert.github.io/spinorama/KEF R3/ErinsAudioCorner/index_eac.html

The graphs look fine (different for each reviewer), but the Olive score (and other specs) (in the blue section) is the same?

If you're going to keep the best quality one, then remove the blue section for the 2nd one (weaker quality review), or at least show that the weaker quality's blue text is not for this review, but for the better quality review. Either way, it will be better than current way of showing it.
