"the SG-570BL with S-150 horn mid-low isn't good between 100 or 150 (the horn name;-))"Why will it expect to be good at that range?? The S-150 horn has cutoff frequency of 150Hz. The suggested crossover point is 200Hz from GOTO.There is no doubt th...

Personal, I do not use WE555 and I do not (would not) use the WE555-type horns. Hypothetically if one would go for 4-way system with WE555-like driver in upperbass then it is valid solution, not something that I appreciate but valid. The WE555 is ve...

[quote user="MINGSU"] Of course, if the space is not an issue, time-aligned installation will be the only way to do. But, in a real world, that is not often the case. One has to live with lots of limitation, so time-aligned might have to be compromis...

Thanks for your comments, Roman.You're someway right... Goto foolishness;-))) maybe... also Mingsu wrote he "never" saw such a (Keith's - or mine) way to use S-150 mid-low horn... everyone's - me too, also with some doubt - copycatting each othe...

[quote user="serenechaos"] The closest I could come to describing the SOUND, when the source was right; (Charles King's Stellavox) & good electricity (JJ filter) was …. being exceptionally smooth [/quote]

user="martinshorn"] What Klaus also highlighted, is the importance to
him to unlimit dynamics - in order to achieve the most live-alike sound. First
of all, he noticed that Goto pleases him the most with uncompressed transient
attacks more...

Josh, I am not sure what you want to say. If you looking to name the reason why you like the sound of Gotos then you are guessing as much as anybody else. I can tell you even more. I very confident that the Goto folks themselves are guessing. I do no...

This is a complex topic to setup a multi-horn system. What do you expect that something like this will come in a step-by-step instruction? It is years of effort to get it right. The discussion that we have here is wrong horn pair up with driver an...

Hi Romy. Sure but its nice figuring out main contributor to specific sounds. Inspiring DIY people to change flavors to their prefs. I dont like the buy or die mindset. I just managed after lot of time & money to get my components to copy the vox ...

Romy,
I am off to Taiwan tomorrow but will ask the question by email. I have not heard that kind of custom diaphragm ever available from GOTO on SG146LD4 driver. I know the 15" woofer can be request with different stiffness of the cone.&...

Hi Josh,I think it is all a matter of perspective. Personally, I would be very surprised if the key elements of the sound of that system that so impressed you is due to the Goto drivers. There are at least three more important things: that big roo...

[quote user="Jorge"]I have seen Beyma rewrite their specs when they redo a driver and even add a letter to the driver for that change, even if it is the same driver.Now I have seen variable FS responses form different drivers of the same model also....

Hello again, Romy...
I totally agree with you about changing the rear chamber volume. It makes a very positive improvement in extension as well as quality. Also, I had never dreamed of a driver with a variable compliance resulting in a variable...

Keith,
I do not see any “O, shit!” effect. You went for 505TT/S150 combination and it is fine. Why after reading my comments you developed doubts? It looks to me that if you do have doubts then you did not have enough rational to select this s...

[quote user="tuyen"]When i change the cutoff of the 505tt to 200hz and 250hz, I experience that same 'hole' you mention about. Hence why I was questioning if it is the 160hz le'clech horn causing this and if using the goto s150 horn with it's di...

up at this site with GOTO 146 driver and
wanted to build a midbass horns with them. I naturally took interest as I never

RobertAren't those meant to be driven by 250W SS amps ? Did you chose driver for your midbass already ? I thought that for this range 8" Lowther DX series with its 50Hz Fs and its "lean" sound could compliment your GOTO drivers (16 Ohm version has 3m...

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