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…Rerurn to Romy the Cat's Site
