"the SG-570BL with S-150 horn mid-low isn't good between 100 or 150 (the horn name;-))"Why will it expect to be good at that range?? The S-150 horn has cutoff frequency of 150Hz. The suggested crossover point is 200Hz from GOTO.There is no doubt th...

This is a complex topic to setup a multi-horn system. What do you expect that something like this will come in a step-by-step instruction? It is years of effort to get it right. The discussion that we have here is wrong horn pair up with driver an...

him to unlimit dynamics - in order to achieve the most live-alike sound. First
of all, he noticed that Goto pleases him the most with uncompressed transient
attacks more...

Josh, I am not sure what you want to say. If you looking to name the reason why you like the sound of Gotos then you are guessing as much as anybody else. I can tell you even more. I very confident that the Goto folks themselves are guessing. I do no...

[quote user="MINGSU"] Of course, if the space is not an issue, time-aligned installation will be the only way to do. But, in a real world, that is not often the case. One has to live with lots of limitation, so time-aligned might have to be compromis...

Thanks for your comments, Roman.You're someway right... Goto foolishness;-))) maybe... also Mingsu wrote he "never" saw such a (Keith's - or mine) way to use S-150 mid-low horn... everyone's - me too, also with some doubt - copycatting each othe...

Hi Romy. Sure but its nice figuring out main contributor to specific sounds. Inspiring DIY people to change flavors to their prefs. I dont like the buy or die mindset. I just managed after lot of time & money to get my components to copy the vox ...

Romy,
I am off to Taiwan tomorrow but will ask the question by email. I have not heard that kind of custom diaphragm ever available from GOTO on SG146LD4 driver. I know the 15" woofer can be request with different stiffness of the cone.&...

It is 4” exit and reportedly goes down to 27Hz. I do not know what a lot about this diver but it might be a good driver for 40Hz horn. 4” into 40hz? God, it has to be at least 16 feet long horn! I would take my head off to somebody who goes for it. A...

Hi Josh,I think it is all a matter of perspective. Personally, I would be very surprised if the key elements of the sound of that system that so impressed you is due to the Goto drivers. There are at least three more important things: that big roo...

[quote user="Jorge"]I have seen Beyma rewrite their specs when they redo a driver and even add a letter to the driver for that change, even if it is the same driver.Now I have seen variable FS responses form different drivers of the same model also....

Hello again, Romy...
I totally agree with you about changing the rear chamber volume. It makes a very positive improvement in extension as well as quality. Also, I had never dreamed of a driver with a variable compliance resulting in a variable...

Keith,
I do not see any “O, shit!” effect. You went for 505TT/S150 combination and it is fine. Why after reading my comments you developed doubts? It looks to me that if you do have doubts then you did not have enough rational to select this s...

[quote user="tuyen"]When i change the cutoff of the 505tt to 200hz and 250hz, I experience that same 'hole' you mention about. Hence why I was questioning if it is the 160hz le'clech horn causing this and if using the goto s150 horn with it's di...

To use a Class D amp on those SG-146LD GOTO drivers? Is it what GOTO proposes? Hm, I do not know, the more I learn about them the more question I their sanity. The SG-146LD does not adjustable resonance frequency. It means that in whatever horn i...

Thanks for all the replies. I've got a fellow hornie friend who knows someone in the Japanese GOTO agency who can understand English. I'll try bouncing the idea off theem & see what they say....

I wonder anyways how Goto arrives at the frequency response they give on the driver label after plotting my 370. And also if the response of one labeled 400Hz to 18kHz is any different from my "400 to 10k" version. Do you by any chance know which one...

Hi Daniel, is there more coming up, do you have more Goto Drivers? Id be really interested to see a SG16 graph :)Keep us posted with ur setup, findings, listenings......

I had a SG370 mid apart only yesterday.I should have taken a photograph.I have also seen the inside of the tweeter.They are very similar,so I have no reason to suppose the low mid SG 505 will be much different.I'll try to explain.I think they a...

I dont know why Goto do what they do...
But if we imagine using only the - good - part of a "perfect" horn/driver combination we will find that the bandwidth will be very small.
