Nearly all manufacturers do not advertise/exhibit their product measurements? Why?

@jerryg123 

I also will bet that Mikes room sounds 10,000 times better than yours!

So you don't need your ears to determine this?  Just your eyes?

… so there is at least one that takes some pride in the measurements.

Sadly those measurements are gated/in-room and as such, have no low frequency resolution to speak of. 

Ok - many people have read the Toole and Olive… While FR is important, it can be corrected with a DSP, but time domain response is not so easy.
Radiation pattern is also not correctable after the fact.  

Notice how the X axis starts at 700 Hz.  Things like cabinet/port resonances are just not seen with that kind of measurement  I am also pretty sure the response above that region is also smoothed and is not raw. 

They are not ported.

If you look at the waterfall along side the impedance plots, there are not hiccups indicating resonances.

I suppose we can bitch about it, but the 1 out of a few hundred should not be whom should attracts the bitching. It should be Revel or or the other “few hundred”.

For a company their size, they should get proper anechoic measurements for their speakers

B.S. @amir_asr 
There is no dishonour in gated measurements… I think even Klipple uses gated measurements.

Do not make out like only Harmon and JBL have a chamber, That could be perceived as being a shill to your old people. 

@fleschler original post may have been taking more of a dig at you than a serious question about manufactures supplying information, but I am trying to stick to the question without adding in his intent.

Not what I said @amir_asr I said I bet. I did not definitively state that it did, However based on the images of Mikes room and your room, I think it is a safe bet.

Now just go away you are annoying and I am not joining your cult.

Is anyone surprised that @amir_asr is unwilling/unable to post his own system? It is curious.

You are like a broken record.

I've been to Mikes three times, including one solo visit. Mike's room is so good my first time I sensed it just walking in the door. Then walking around taking it all in the sights and the sounds this sense of acoustic bliss grew and grew. At one point during the first visit with someone else in the sweet spot I took the opportunity to stroll around checking out the sound from lots of different places. Growing more and more impressed, finally I went right into a corner. Try this some time. Very hard to not have boomy bass in a corner. Nothing. Nada.

Looking around it was apparent even before Mike explained anything that he had some false walls and storage hiding bass traps. The openings were nicely covered in fabric making them appear as if they are not there at all.

If the traps are hidden the diffusers and absorption panels are not. The whole room was professionally designed, and then refined and perfected by Mike making countless improvements over the years. The result is the most perfect acoustic space I have ever heard. 

Just outside Mike's listening room is a very nicely stocked wet bar. This is where I discovered the most delicious whiskey of all time, Angel's Envy Finished Rye. About the only thing more delicious than that is when Mike put his dubbed master tape of Pink Floyd Wish You Were Here on the Studer.

In short, it is hard to think of anything more disastrously credibility destroying than to criticize Mike's room, or hospitality.
