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...

kodomo, there is a thing that you need to understand. The
objective to have bass channels outside is valid but it is applied to a perfect
condition when you have unlimited width. In the situation like you’re the objective to
have bass channels ou...

[quote user="Jorge"]Hello Anthony,I did experiment with metal tubes for bass in a sealed configuration as you are planning. The weight of them, even made out of thinner than you would like steel, is prohibitive. If you make them out of aluminum pipe...

I have been playing around with speakers for a long time, and things started snapping when I got into horns. I have a system right now with an upperbass horn from 140 hz turned form MDF up to around 700 hz, to another horn, and another and a super t...

Thanks, Wojtekm it sounds like interesting experience. I would mention that you use K-horns and with them the loading would be much more capriccios then it would it be with stand-alone infinite-baffle bass section. Did you seal the space between the ...

Paul, l I have written about it somewhere: the passive speaker-level crossovers on bass channels are no good. Marko has 250Hz that with 3rd order would be around 10mH and 2mH. With air core then would be very large coils with huge amount of DCR – ver...

Romy,
More to come soon but a couple comments regarding bass horns ( and one on Tractrix horns ) :
The Edgar Seismic subwoofer ( 18" JBL E155-4 hyperbolic-exponential folded horn, 40 Hz Fc ) works very well in my room - much better than the 1...

I think the usage of Romys Injection Channel has misguided you to think it was implemented because of a certian lack of tone or some sterile sound, nothing of the sort, I cannot blame you for not having listened to Romys system, but theo...

jd, I cannot see any of PDF files, probably my current networks kills them.
I do not know the AK150 drivers. I know AK157, AK151 and K15/40. If they have significantly lower free-air resonance, at 30-35Hz then I am not sure that they would be ...

I heard the Everests recently at the Munich Hi End show, unfortunately they were being used in an active vs passive display/dem , you could tell when the Everests were playing as the active speakers had a sound like an inflated balloon being rubbed w...

[quote user="Paul S"] Some of those Altec horns were textbook examples of both types of bell-like resonance, where the body of the horn itself resonated and certain bell-like artifacts were created/amplified by/in the horns' mouths. [/quote] Hmmmmmmm...

I note English Mfgrs tried low power ribbon Midrange horns in the 50's (Decca, Kelly & Quad also made one!).These were probably inspired by the hi pwr prewar? Klangfilm ribbon horn (would like to hear one of those!) But, after Peter Walker moved ...

hello again Romy, cats, friends...

Hi, Tim. This is difficult question, and it is difficult in it’s abstractivnes. I really do not understand, or understand but refuse to acknowledge the validity of the word “respectable”. How valid for YOU would be a “reputation” of this driver if it...

BTW, purely hypothetically, Jessie, if you have a long harrow room then did you consider to put your bass horns vertically, facing them mouth up, pretending that they are large vases? It might be a new kinky surreal home decor and you can make the th...

[quote]might I ask why[/quote]1.)the bass will be pretty coloured...mouth not large enough for proper bass response..

Well, yes... I've not been to prison in over two years! Apart from keeping me off the streets at night, the results when listening to one of the 40Hz horns were, dare I say, encouraging, though I do hesitate to say so, as the "evaluation" was carried...

Hi Jeff,I am certain that the best midbass was NEVER in a corner horn. Every fold in the horn is a new resonance. Corner horns need many folds...In addition, if you are very "anal retentive" about phase alignment - how do you integrate a corner horn?...

[quote user="Horn Savant"] I think it's about the same as free-air resonance - backwave to entire basement. Precedent: pre-war theatre horns(open rear like Shearer/ERPI)(unlike post-war reflex tuned designs like Altec A4)(I don't like reflex boxes - ...

Rewind, this is funny because it is not at all terrible. I have thought for some time I would try paper mache "wings" on a WR driver, but I've never gotten around to it. Believe it or not, your little demonstration has rekindled my interest.At some ...

[quote user="Jorge"] Lets just say that TH bass is much cleaner and generates a different "bass sensation" in the room. Once you get used to it, it is very difficult to go back to boxed bass.I find the sound similar to what a Mid bass horn woud pla...

Yes, I should have said modular like your bass horns, but with much smaller segments, e.g. 36 segments of 10 degrees. Assuming one keeps the profile the same, the only difference between different sized horns is scale, so a single mould "capped" at v...
