Post Subject: GOTO 146: Quite accurate prediction.Posted by Romy the Cat on: 2/17/2016

Some of you remember as a few months ago a Russian guy pup up at this site with GOTO 146 driver and wanted to build a midbass horns with them. I naturally took interest as I never dealt with Japanese 4” compression drivers and I though it might be a good learning vicarious experience. I did express some warnings about GOTO 146, not that I have my own experience with it but rather productive warning, something that in my view derived from the driver design. Eventually I felt that this Russian guy is nor particular worthy material for collaboration and I withdrew from his association. I still sometime monitor what he is doing and the direction he is going. It is no surprise that he in his playback progress is running in his successes and failures directly along with the plot that I predicted to him months back. I found this “plot for retards” and this Russian guy unfortunately fits the bill. However, if analyze what he does and put out parentheses the stupidity of his action and his obvious disability to realize what he is doing then his actions and his results do objectively demonstrate something about GOTO 146 driver and what is the most important in a way demonstrate the value of my initial predications. The predications was about using GOTO-like drivers very cautiously as this over-magnetized topology might not be suitable for bass. This is very interesting concept that I was pitching in multiple threads including the electromagnet thread. From what I am seeing that Russian guy does indicated to me that he hit the problem I predicted. Without having my own ability to experiment with it I do not think I will progress in my judgment but the word of warning is still there: beware the overly controlled drivers as it might compromise bass softness. Sure there are way to deal with it by imposing different loading mechanisms but this is very murky subjects and you will be stepping in very uncharted waters.
