Post Subject: Murat 2017 (Martch)Posted by Romy the Cat on: 3/30/2017
It is not a secret that my short interaction with Murat and my observation the progress he has with his playback made me to feel that his is an idiot. There is nothing new in it, most of accidental audio people are idiots. Nevertheless, I think it is warranted for me to make some observation about the installation he “ended up” just for sake of general audio education. I use the phrase ended up as a colloquium because he ending up for this audio person is a transitional stage before his absentminded compulsiveness unleash him to dig into a new bogus project. 
 
So, after all parley into multi-channel last year Murat ended up with something like this: 
 
1)      Upper Channel:  400Hz and up viaAER BD4 in 650гц La-Horn, firs order subtraction filter.
2)      Upper bass 100-400Hz, GOTO-146 in half of 120гц La-Horn, 4th order low-pass
3)      Midbass 40-100Hz GOTO-146 in a spiral horn
4)      20-40Hz is Velodine DD-1812, 4th order low-pass

As you can see there are plenty of typical slips expected from a person who has no cultural ears, a lot of attitude about himself and away willing to go extensivly over his filed intensive tasks. 
 
The selection of BD4 to cover upper range is OK move in my view. You lose in dynamic range and pick up some typical Yellow driver compression but you gain in upper drivers integration. To do the integration manually with multi-channel require some actual skills and time, so a wide-range driver might be a good helper in there. I also think that BD4 might be a fine sounding driver, I very much do not think that it might be used at 400Hz and first order but it require some ears and listening intelligence to understand. 
 
The Upper bass in a Muslim horn. On a picture it looks like elegant solution but looking one layer deeper the ridiculousness of it is popping up. The  channels is not high-passed, the driver is not tuned to horn, the LF gain in Muslim horn is much lower than horn rate would suggested, so in many ways the channels is acting like a direct radiator, the need of using of 4th order from top only confirms it. It is kind of ridicules that a person had brain to make money to afford GOTO-146 and in the same time do not have brain to put it in a reasonable use.
 
The Midbass is spiral horn. The spiral horn is an old story and the lowers of sewer sound do love them. It is ironic that “sewer sound” from those type of the horns was not invented by me but shared with me by one of quite reputed horn maker (including spiral) who was laughing with me and told me that his customers thankfully are deaf idiots who love “belching sound from sewer horns”. 
 
The lover channels with Velodine DD driven crap I do not even want to discuss. I am sure it is a comfortable solution but it has nothing to do with Sound. 

I do admit the there is some element of elegance and simplicity in Murat’s new playback but at the same time the installation screams: “My owner is a Moron, I hope he will change me soon”. Do not worry, he will…
