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...

It is not surprising that the subject of horn is as screwed as the subject of drivers. It is understandable as driver must be made for specific horn loading, not one make drivers properly, so what the horns are made for?
A horn is a very simple dev...

+++ Going back in time to your Super Macondo with the midbass horn, I'm wondering how did the big horn influence your perception of Macondo sound if you remember?
Yes, it is very very good question and essentially the question which r...

[quote user="noviygera"]There seems to be a lack of useful feedback on the actual sound quality of these oddball, relatively rare TAD mids. So I think it would be helpful to share some basic observations I gather after listening to them for a couple ...

well, i believe that the popularity of the better fostex tweeters comes from their typical, off-shelf sound which is soft and easy on ear in comparison with super-resolunt Ti or Be diaphragm equipped competition. they very much suit any sharpness com...

[quote user="op.9"]Anyhow, what are the 2" comp drivers that ARE any good and are available comercially? I didnt go with any JBLs because I had a very bad time with the 2427 1" version, could never get any music out of it. [/quote]
I would be surpri...

I like this Polish guy in your tube interview. I hate his speakers
of cause. The best this is this YouTube interview is the Peter Breuninger’s proposal

Yes, if you are at 40Hz first order then you are with regular dedicated LF channel and tone is certainly a subject. The entire definition of ULF channel inkstand or LF channel is that ULF channel has no tonal information. It is very same like use twe...

It is true, so the amount of the channels is not mandatory or necessary qualifier for sound reprodu...

Thanks Romy and Paul for your comments.

We all know how low-power SETs sound driving low-sensitively ported speakers. The Morons feel that it they have “enough volume” then their SET is good to go. Of course it is not the case and low-power SETs shell not driver dead speakers.
However, I ...

I'll try to make some comments on Feastrex Sound in this post. It is always difficult for me to isolate the sound of the individual parts I want to analyze. Like in this thread, which has partly evolved into the effect of all pe...

I find that one of the most interning and stimulating ideas that you expressed was your experience with your bass horn

[quote user="haralanov"] Romy, the actual sound benefit of this 4-channel upper bass configuration, is rather in the type of sound presentation. The commonly used single upper bass horn (or direct radiator) sitting under the midrange horn, gives the ...

I run the driver tube at 170V @20mA. I don't think you need to run this tube at high current. It is very linear with wide signal swings at this bias. I can get roughly 70Vrms out of it. Output stage clips first, driver continu...

[quote user="Joe Roberts"]The Manger is very different from Lowthers and other paper fullranges. It is very balanced and not peaky at all. Lowthers are lots of fun to experiment with but it seems the Manger is less idiosyncratic sonically, although i...

Thinking about my Vitavox S2 “fundamentals channel” I can’t stop think about my hypostatic view about the horns. Year after year I was mucking what GOTO does when they introduces a horn for a couple octaves. Ironical now I am truing to do the same fo...

It is one thing to swap caps in a pre-amp, or ICs; it is another thing entirely to swap transducers. Nothing brings change like a speaker, and it may be that nothing is less understood in terms of the pure sound that is - ultimately - the only t...

one would take full advantage of what can be done in the digital domain so that the horn mouths could be arranged, not for time but to clean up their other interactions. This would be digital the entire way, solid state music files, digital amplifica...
