WTF is happening?! What Hi-Fi? is now publishing measurements?

[mansr]

Interesting:
http://newporttestlabs.com/

With a whois lookup, the domain name appears to have Australian connections.

That page at that URL is identical to What Hifi apart from the title instead reading AVHub Home Page. I sense an affiliation.

 

[jonfitch]

What Hi Fi might as well be a decor magazine with how much insight they offer into audio products...

I beg to differ. Have a look at the spectrum of random song I picked from my NAS (this one is Ultravox - Vienna). So, while woofers and port will happily play the LF (with port singing at -22dB) we can actually se that the 650Hz notes played by the port will be heavilly competing with the music signals at 650Hz which are also 20dB lower than LF. Do we really want that to happen..?

Certainly it's not ideal, but I still think that it's not very likely to be significantly audible.

My greater point was that this type of port noise is very common and usually actually significantly higher in level. I'm well aware because I measure the port response for every speaker I measure and 22dB is quite low compared to the typical port resonances.

Aside from the 5 speakers or so I linked to in my previous post, just to illustrate the point, here's a random sample just scrolling through stereophile reviews:

Well, ok - I'm aware that it could be even worse than that with those Focals, but why do you think it is not an audible problem? I clearly showed with the spectrum graph that port noise is at the same level as music at that frequency, so how can you be sure it is not audible?

Actually, I'm not amused by correcting Your perspective. The 650Hz are not "made" by the port and add on to the music or whatever. It is so, that the port lets something through, that was initially in the spectral content of the program. Only that it is not the intended path of that content. Or, at least not in that intensity. It is a resonance, namely of an open pipe, that makes the port so transparent.

In consequence one has to estimate the part of the driver's outside radiation, and the other part, driven by the inside radiation, which shines through the port. Again, it both comes from the original content, no add-ups here. I leave it to You, to scientifically add 0dB +( - 22dB ) = x dB. Calculate the bump and maybe the directionally varying phase shift.

All I see is quotes attributed to Steve Holding. There is no evidence that such a person even exists.

Dialling back the cynicism a little, maybe that Aussie hi-fi rag has their offices in one of the Newports and Mr Holding works there, Newport Test Labs being their cute nickname for the back room where they keep some test gear. I base this theory on the facts that the magazine is run by Future Publishing and that all the graphs have "Image credit: Future" written below.

What's one more scandal in audiophilia eh?

"..There are people on other forums that actually believe amir is an Asian woman..."

Where is this?? Pls give a link, i need a good laugh today.

I found it over on CA Forum. Made me chuckle again.

 

[Wombat]

And the panthers are pink. That seals it.

Must be some kind of a joke. Nobody can be that stupid or?
HeHe i'am a bird.

 

[Voo]

omg, the science has fallen.

Has he ever provided evidence he IS a man? Double blind maybe it would be impossible to tell.

WHERE IS THE EVIDENCE NOW, HUH?

 

[tuga]

What Hi-Fi has merged/bought Australian Hi-Fi magazine which publishes measurements produced by Newport Test Labs.
Click the link at the end of this PDF and see where it leeds.

My guess is that Newport Test Labs is a guy with a measurement facility in his garage.

 

[Objectivist01]

What do what Hi-Fi mean by “lacking rhythmic drive” ? they keep using this in negative points of many devices.. any one knows this jargon?

Only pictures but they could be photoshopt???


If @amirm would be a good looking asian women, that would be great! i had to mary her.

That's ok... isn't that what Amir is doing?

I would recommend people obsess less on who Steve Holding is and just consider whatever objective data he provides...

You'd be too late. That photo was taken at the woman's wedding.

This might surprise you, but I do not look like a big "K" in real life.

Oh come on don't destroy my dreams!

Ok sry guys it's in german.
But she is a Dr. in chemistry. And a science communicator. Maybe @amirm looks a liitle similar? And hifi for me is more interesting than chemistry.

That would be cool.

I think it's time you meet Amir Majidimehr.
