Yes, it turned out to be the emails from GOTO importer. I am not completely understood if the horn at the picture above is an official GOTO product. The Ming Su said that the horn was build locally by Jeffrey Jackson with the support of GOTO but then...

[quote user="Jeffrey Jackson"] first, basshorns... the basshorns that I posted here some years back are my straight ~50Hz horns (my memory is fading)... they are 8' long... then rear chamber.. mouth ~ 3' x 4'... throat ~8" x 8"... rear chambers of va...

[quote user="Jeffrey Jackson"] so a few things... one, there is a pair of Goto 370 on eBay and pictures of insides... the newer ones are made the same, but it seems that the execution has gotten a better/cleaner compared to these.. my diaphragms look...

[quote user="Jeffrey Jackson"] Also, I had never dreamed of a driver with a variable compliance resulting in a variable free air resonance... such a toy would be wonderful with custom midbass and bass horns... [/quote]
It is why I use cone drivers f...

[quote user="Jeffrey Jackson"] It seems that I do agree with you about the sound of compression driver midbass.. at least from what I have heard in my own room.. I have heard the big ALE drivers you mention on a bent steel horn similar to what ALE bu...

[quote user="Romy the Cat"]
...this interesting point has no practical answer. First of all in the case of Rakesh horn what N-Set proposed is not necessary. Those 115Hz Hasqiun-style horns that Rakesh emulates are well dumped with own mass and own ...

Thank you for giving this matter your attention. Jorge, I was intending that the AK151 be employed within a horn. Further, once I had settled upon the driver compliment, it was my intention to retain the services of Jeffrey Jackson, since I am not su...

[quote user="cv"] That said, I do have is a single 160Hz/1.5" finally up and running on a compression driver, and it's a different world - stunning. Actually the results are exactly as JJ described. [/quote] The JJ, is it Jeffrey Jackson? I have no i...

It looks like Jeffrey Jackson formed a new company and along
with his friends makes a new horn-loaded products. http://www.wheel-fi.com/
….and do not miss the video.

Hi All,This is Ming Su and I am the US distributor for GOTO and J.C. Verdier. I thought that I will share with you about my new midbass horn. As you know by now, Jeffrey Jackson from http://experiencemusic.net/ help me on this project.&nb...

Jessie-Good to hear from you. I am very motivated following your progress. Thanks for the inspiration.My room size is around 15' x 18' x 8'. At this point, I feel that a proper 60 - 70hz midbass horn is physically the largest I am realistically pr...

[quote user="twogoodears"] I agree with Mingsu questions about "what" physical area must be aligned, as every inch +/- gives sometimes different results... [/quote] Come on Stefano, you do not align the “physical area”. You guys are so preocupated wi...

[quote user="MINGSU"] SG505TT + S150 horn crossover at 180 Hz is not recommended by GOTO. The SG505TT driver is not recommended to use with single throat S150 horn. Double SG505TT driver is recommended to use with single...

Hi all... yes, a clean power is paramount for a clean sound... I run my turntable and pre-amp on batteries and the difference in sound is amazing, while I never used outboard filtering on amps, BUT I have a public mains transformer at 10 meters from ...

[quote user="Jeffrey Jackson"] so, my straight horns... I like them very much.. I built mine similar in style to what Greg B linked, but obviously much smaller.. mine are just under eight feet long (length of a sheet of plywood) and have a mouth roug...

since I came to GSC, I became more and more careful (at least trying) in proper choosing words, due to the need of expressing myself in a language which isn't my own, some finesse and subtleties get lost, so further explanation or underl...

Romy & Dominik,Mingsu is a DEALER... more or less about business and money, did you really expect him to be a horn expert?
From Jeffrey Jackson:

Dear N-set,I do not set out to copy Romy's speaker installation for a number of reasons, foremost among which is that I have not heard it. I'm sure that it sounds excellent in his room and with his ancillaries, but since mine are/will be different, I...

Romy,I merely thought that you felt I was riding roughshod over your advice, when it was in fact a degree of naivety requiring extensive clarification that may have made it appear thus. Regardless of your indifference to praise and/or criticism, I'd ...

Jessie,
When I spoke that I would go most likely for exponential I did not mean the Exponential vs. Hyperbolic but rather that it would not be a Tractrix. I have no specific preferences for Exponential, Hyperbolic or any other long profiles. A commo...
