You can hear a full 4 way GOTO in this event next month. Come down, stop by, enjoy and judge yourself, in person. http://www.capitalaudiofest.com/ July 8-10 in Rockville, MD....

Hi Romy
a good sound in a room does not depend only on the speaker chain, but essencially also of the room acoustics. Probably many of the Trio systems didn’t sound right just because of that…. I was at Holgers Home in Lautersbach back in 94. He ha...

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"]Good, I hate to know everything! I just wrote that the poor Murat
with his neurotic audiophile itch is condemned to go brainlessly very soon over
many drivers. A few days pass and the guy have brought to his room an army ...

[quote user="Romy the Cat"]The Supravox was
12” the Goto 4” how did you convert one into another? You would need a 3-4 feet
adopter to do so.[/quote]I used GOTO's converter from dual 4" to aprox 200sq sm2 throat. It is still 2 times smaller than ex...

[quote user="Rewind"] I kind of got stuck in selecting an upper midrange driver, above 2kHz. If a driver is going to screech in your ears it is going to be in these frequencies. I was never really satisfied with the range of 1" compression driver...

Hi,I am slowly building my own Macondo. I understand why the injection channel is there. It brings some kind of softness that the compression drivers lack. I am using a 12" JBL midbass driver (~100dB sensitivity) in a 50L single driver Marshall cabin...

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...

Hi Roman, hi all... intriguing post and interesting questions, as I've been for about 20 years a triode and, before, a tube user and a glowing-in-the-dark maniac.My experience...I purchased - years ago - an Hiraga 20W which I used as a bass enclosure...

Do get an RTA, it is amazing how different the frecuencies are from what we imagine, 50 hz is very low! 150 hz is a vital freq, and a lot of female voices have a very nice fullness at 150 hz. It is hard to tell without measuring what is happening ...

[quote user="Saturntube"] Anyone has some sort of comparison between compression drivers against cone (dynamic) drivers in a this huge mid bass horns, or even upper bass horns. All I heard are this guys from Germany with the out of reach expe...

Thank you, Romy, for input.
I'm still following my initial concept:
Bottom horn is finally ready and I like the sound with 12" Supravox in it. Moreover, I don't feel the need for Tapped Horn...

Tonight I finished two
horns at once. One was a shortened Goto S-150 horn that now has a
Fane S 8M, without back chamber so far. Dimensions are now 1.1m deep, 11cm throat, 75cm mouth. It is replacing the Avantgarde
Trio midbass horn r...

thanks I have a few questions to ask if you do not mind:
1) Did you experiment with surface of the horns and a negative contribution of smooth surface to Sound?Smooth surface are fine don't waste my time on a trival matters.

I went to see what Speedysteve7 does. I did not read the text. I just glanced at the text and seen the mentioning of multisampling with digital amps, mentioning of digital crossover. All of it and the most important the rock-end-roll crap the he ...

I dont want to hack this thread into TH, I tried them with sub-amps 150 watts and they didnt sound good, but I was using a passive preamp, when I added an active preamp things started to get better, now with 12 watts and a a lot of gain, bass is ama...

Hello Johan, Great pics, the diaphragm appears really thin, almost like gold leaf for guilding...I have a question about the screw mount that Goto uses. Did you by any chance find some kind of flange (for pipes) that would work as an adaptor? Pe...

Hey Romy,The Goto drivers (505TT, 100-8khz) and horns (S150, 150hz round exponential) finally arrived. I've only had them for a week so I can't say much about them besides they're not a simple drop in replacement of the previous 10" TAD woofer (200hz...

I suspect you were both right.We each have our own priorities, but I did find a couple of his youtube videos to be interesting, as far as one can tell anything useful from compressed video.Not the point though really.I'm more interested in this idea ...

I'd like to point out that Fostex 500 MKII is very much not sharp and artificial sounding. If anything it's an opposite -little too syrupy , soft and round so it blends with cone mid better than beryllium tweeter. I have no first hand experience with...

[quote user="anthony"]Regarding the other questions you asked, I am basically duplicating Romy's system as my starting point with horns.[/quote]Yes, as you can see my approach is also very similar.Two major differences: TH and Fundamental frequency r...

Hey Romy,Goto makes 12" and 15" woofers at 100db. I recently found out they make a small two way system using an 8" woofer. The 8 incher's range is 55hz-8000hz so I'm thinking it might be a good candidate for use with 60Hz horns. Looking at Goto's 12...

If time (Endo-san and mine...) will allow, I should also visit Endo Labs of ALE fame... sure I'll have a listen to a 4 ways system in Tokyo area with bass driver and concrete horn.Re. "tilted high frequencies"... no, Roman, it's not me experiencing s...

Romy, whether intentionally or otherwise, "murky waters" is a beautiful metaphor for the Western Electric route, in my experience; that said, just because something does not exist, does not mean that I might not be made so with a less hidebound a...

Daniel, seeing your words describing needs for live sound, i seriously recommend to copy Klaus Speth' System in a first instance. You can go further after that. But that thing had it all, what anyone needs to feel the art become alive. I can ensure i...

From the perspective of pumping of atmospheric pressure the ALE bass drivers might be more capable transducers. It or might not be so as well. To get 40Hz at 110dB in 5” it would take some excursion. I am sorry but you can’t bend the law o...
