[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...

Hi Romy, Hi Jeffrey Steve and I have been working on the bass compression driver for quite some time now, about 3 weeks ago we made some design changes that really paid off, as of now I'm convinced that a compression driver is...

[quote user="Jeffrey Jackson"] Ming would like to provide this custom basshorn service to his customers in the US market.. Goto Japan has nothing to do with this... [/quote]
Very cool, the more “hornier” the better as far as I concern.

[quote user="cv"] Did I ever mention my sulphur hexafluoride idea to you? You fill a horn with this gas, sealing the front with some loose fitting heavy grade mylar or whatever. The horn can then be 44% of the size you'd otherwise need. [/quote] Hm, ...

Romy, do you have first hand listening experience of these YL drivers? If so, in what sort of installation? Doubtless you will refer me to an extant thread, but how is it that you dealt with the S2's secondary resonance? "Killing the S2's sound" in a...

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="noviygera"]And one last thing for now I'd like to ask you. Would you know of a builder in the USA that can design the horn based on my requirements so that I do not attempt to be a horn designer? I can get the design built locally.[/...

[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...

Dear All,Thank you all for your assistance, especially Romy, whose information has been particularly interesting. I have been in contact with Jeffrey Jackson, with whom I have discussed my driver preferences, and arrived at what is essentially only a...

If you look that Jeffrey Jackson’s midbass horn then you can see two pillows stuck into the horns belly. Let presume that the pillows were placed there in purpose. So, here is homework for people who would like to flux their horny mussels: what is t...

[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]

de Charlus, I still do not think that there is such a thing as “ the only a theoretical starting point”. Perhaps you were inspired by Jeffrey’s recommendation that has more experience in it then you. Still, the compression drivers loaded into giv...

Which RCA driver you use? RCA had a few drivers the pre and after war. I am familiar with a few after war drivers that I tried in my 330Hz horn and I was not impressed. Reportedly the pre-war MI-1428B shall be the one to play with; I did not have thi...

with his friends makes a new horn-loaded products. http://www.wheel-fi.com/
….and do not miss the video.

Thanks Romy,I particularly appreciate the advice on the Goto issue, although a sojourn in Japan would be delightful too, come to think of it; in my experience there's no better place for culinary and audio tourism combined. "Local" support in the cas...

Hello,A couple of things to correct here - the horn flare is not conical even though the exterior surface gives that impression.Also I don't believe Jeffrey has any affiliation with weiss or other industry types at all - in fact, from what I've seen ...

[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...

[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...

Your experiments bring to mind the excellent results Jeffrey had with his half horns:http://www.goodsoundclub.com/GetPost.aspx?PostID=7467&Phrase=VSACIt is also good to hear that you have an "assistant" Jessie.Very good indeed....

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 ...

Hi s e r e n e c h a o s,Ok, now I see from the 6moons VSAC photos how the woofer was loaded...I was 'worried' Jeffrey sliced his woofer into two equal halves and then placed a 'dividing board' straight through the woofer (as in midbass horns '...

Hi RomyHow very strange you mention this... Dave and Jeffrey have been working with a somewhat similar concept.The design you have doesn't look right - it's missing a time constant; you need another cap there. Where did you find this schematic?...

Well on the upside, I suppose midbass woofer cost is reduced by Half..Seriously though, I'm curious what shape throat and woofer (or driver) Jeffrey used in the ~50Hz bass/midbass horns.Neil...
