Post Subject: About the Goto SG146XX…Posted by Romy the Cat on: 5/23/2017
Hm…m… I do not know how about that.
Well, the SG146XX
where the most interesting from one perspective and the most problematic from
another perspective. Goto, never gave to SG146 an option to moderate resonance
frequency and without it I feel it a great waste of the drivers. The fact that
they did not have the provision to do mitigate Fs is indication to me that they
have very little practical understanding how compression drivers are loaded.
The fact the Goto own horn were very bad is just an additional evidence of it.
The idea to have ultra-low
mass and well damped diaphragm with super powerful magnet is not bad idea and a
few Japanese companies did ii: Condo. ALE, GOTO, Onken, YL. It is arguably
beneficial for higher frequencies but I feel that it is a bit dubious for LF.
If you play with electromagnet driver then you might learn that whatever
combination of current, coil turns, voltage you have you will not be able to
get proper harmonics at lower end if you have overly stiff diaphragm, In my experiment
I always was driving my electromagnets down 1,4T-1,6T to get proper sound at
lower MF as at 2.0T of higher I was getting
very impressive HF and too “firm” lower end.
I was trying to advocate this point a few times and the last
time was in the Murat’s thread, the Moscow guy who was trying to use SG146 with a quarter of 40Hz horn but he
was kind of idiots and was impervious to anything that required an audio
IQ high then the side of own shoe. Still, the experience of that Moscow dude
(the thread is somewhere here) was wonderful illustration to my sentiment. I am
not the person who would judge about Sound of playback based upon YouTube videos,
they all horrible, including my own. Still, if you listen ANY of the YouTube videos
where the bass compression drivers used (including the Kato-san's and the Russian
guy) then you can very clearly hear the signature sound of the compression bass
driver with over-controlled diaphragm. I feel that there IS a way to deal with
it but no one does and it looks like no own hears it among the Goto users.
So, for sure that SG146XX is unique driver but so far I do
not see the Goto users convert the drivers into unique sonic results.
