hello again Romy, cats, friends...
I built this horn for Ming Su, the Goto USA importer... I have posted on your site before about midbass and bass horns... I listen to eight foot straight 45 Hz horns... and as partial payment on this commission ...

"another big selling
point to me was the 505 being a low resonance compression driver..
there just aren't many drivers with a resonance in the 80 to 100 Hz
range like this driver... I have just begun my playing, but am already
quite taken by it.....

Romy, The bass horn project is still going. I have re-arrange the position of the bass horn. Check out http://www.goto-unit.com for most recent pictures. I finally received the GOTO SG38WNS 15" woofer and GOTO SG188S tweeter this week. My next step i...

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 throat S150 horn.&nb...

Hi Romy and thanks a lot for the always interesting topics and discussions going on... I'm quite new to DPoLS and consider the approach of "obtaining sound in a room" more than "speakers positioning" - too often to WAF fullfillment and aesthetics, th...

Thanks, serenechaos. I have a 37FRP is looks like falling on my laps, OK, I made it falling on my laps. It is as I understand the slowest GOTO MF. What I am interested is to see if GOTO will be able to add any value beyond where I am with my Vitavox ...

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...

[quote user="Kcct82"]On to other things... now that we've been using the GOTO SG505 for a while, the verdict is that it does not sound good below 290hz. [/quote]
As I understand you use the GOTO SG505 in 150Hz horn and report that it does not sound ...

Ming,
what you say is not exactly accurate. I have MANY desiccations about it with number Goto users in past and if I am not mistaken then even some kind GOTO official from past event argued this point with me. He insisted that Goto require 4...

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...

Hi,this is my first post. This forum seems to be the hotbed for Goto discussion of some sort but there is barely any data but only a swamp of assumptions. So I bought a pair of SG-370DX drivers with S600 horns and measured them. Here's the frequency...
|

The sticker on the driver states a frequency response from 400Hz to 10kHz. Others say 18kHz. Looking at what's going on I wonder what the condition for these "10kHz" might be....

I would like to pass my observation about the whole notion of
Goto vs S2. Some might feel that that my observations would be less relevant as
I personally did not experiment with Goto drivers. So, there is no reason for
you to read further. I head...

|
[quote user="Romy the Cat"]Oh, God, what the measurement microphone does at the mouth
of the horn? Is it where you measure your responses? I hope not. Also, even over the bad sound of YouTube
video it is very clear at the example you provided us t...

Hi there, been reading this thread and I wonder if the Russian guy liked GOTO for what it stands for then why use it with anything but straight horns and why use it with tube amps?If he knew history and design philosophy behind GOTO his choices are v...

really know about this, I heard a GOTO system with the GOTO 505 in the

better in this range wit...

I shold make it clearer:The Goto was used in a Goto 150Hz horn, crossed at 180Hz.I guess that is a proper implementation for Goto.The Fane was in a 140Hz tractrix horn with a 10cm throat and a not optimised (to large ) back chamber, and no crossover ...

I did some experiments today again with GOTO in my existing horn and it is obvious for me that I need different horn for GOTO.Existing horn was modelled and designed for Supravox and I see perfect curve with it.But GOTO in it shows same curve for 50-...

FYI - for all,The GOTO is a very small company located in Japan that has devoted the whole 3 generations of GOTO family to produce only one product line - the GOTO speaker driver. The annual production capacity is 240 driver units which me...
