...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 ...

At recent Nord-West trade show Jeffrey Jackson, the guy who runs Experience Music site, demonstrated his new horn Installation. I know little about it and would like to make some comments about what is feel is obvious from the image.
It is 5-ways ...

[quote user="Romy the Cat"] Try to drop the Altec in 400Hz horn down to 1000 Hz -700Hz and arm your Oris with a MD driver with a good lover midrange driver (B&C of whatever you use) You will be able to go away with 4 channels… You have a lot of n...

With Ming permission I post a fragment of his emails where he describes his midbass horn. It appears that he uses cone-drivers with ltooooooo ow Fz in non-compression application with no back chamber. Now it is obvious where he is losing his midbass ...

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...

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...

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="de charlus"]Romy, do you have first hand listening experience of these YL drivers? If so, in what sort of installation? [/quote]
Nope, I did hear neither YL drivers nor ALE driver, as least consciousnessly.

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 ...

Hello Jeffrey,BUILDING UPON the inherent/latent Lloyd Wright-esque and Frank Gehry-esque aesthetic potentiality of your midbass horn design, and visually integrating the total horn package as a system within these aesthetic schools (or derivatives th...

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...
|

Mats, I do not know who is Jeffrey is, anyhow, your horns look nicer this time. You need to figure out now what would sound more interesting: the 8PS21 at its higher knee or the Altec at it’s lower knee. The important would be that beside thier absol...

Ok, understood, at least somewhat. Are you suggesting that the S2 operates at the frequencies between 1000hz and 3.6khz? I am not insisting upon using the driver at the frequencies that I was initially suggesting; far from it, actually, as these were...

[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...
|

Ah yes, sorry - that wasn't remotely clear. The drivers I have played with briefly are S2 and field coil RCAs, both have the same 1.5" throat. I was referring to my initial impressions of the sound on Martin Seddon's 160Hz horn (T=0.8 JMLC). Previous...

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

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...

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...

Hey Romy... you could be right about the ALE's.. I certainly did like them, but when I went back to that familiar recording it was definitely shelved down low.. it would be easy to assume that I thought that they were "lightweight" because I had...

Hey Romy,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.That said, this approac...
