Hi Daniel, is there more coming up, do you have more Goto Drivers? Id be really interested to see a SG16 graph :)Keep us posted with ur setup, findings, listenings......

Looks like 370 to me :) at the bottom there some specs (though the crossover is not absolutely correct, i asked Klaus)

this article is a pain to read. Its from and for old bitter „everything was better in the ol‘ times“ folk. It’s blindly (non selective/ unspecific) supporting any current vintage hype. Also it measures progress exclusively by the top notch? What a no...
|
|
ya that’s likely where the truth goes. I had it once with electrostatics. Theyre most bitchy in regards of correct positioning in the room as we all know. They’re a lifetime task to find DPOLS. I tried to move around and found huge difference. Some c...

|
Yea. In some systems, mostly trivial / conservative direct radiators in small monitor size, respond to the normal interpretation of frequency graphs very well. With more exotic and uneven dispersing systems it seems to get more difficult. I had it co...

Hi Daniel. I mean the window, after you sweep 10 seconds, and fuzz shows the IR. You can change the IR windowing on the preferences panel... like crop/cut the analyzed part of e.g. 1ms before the peak and then duration X behind the peak (here i asked...

Hi Daniel. Sorry i meant the throat, not the mouth. But i think you mean the same :) Just for anyone else reading this not to scratch their head. I heard that on cheap plastic horns the mouth often rings, is loose, or not perfectly centered and then ...
|
|
Hi Daniel, great initiative! More of that :) Can you tell us more how u measured??Like loudness, distance, settings? I know that Fuzz likes to sweep too short (0.1 sec. logsweep) and allows many crappy windowing settings...Maybe a nearfield (close to...
|
|
No i dont have oppinion about this specific one. The room response looks ok. Take the XO, try it, sell it :) but yes, the acourate XO requires 3 Amps then. Still, worth it!...

Hi. Well the behringer belongs probably to the most famous and also to the worst quality wise. Sure the passive sound better...Id go with the learnings from the behringer and apply it in a clean xover, either active or passive or even digital - but n...
|
|
Hi, true thats why i wrote designated amp (Active). As a passive xover thats rather difficult, so try a low Q filter type that increases steepness slowly. Like a Bessel (Q 0.585) or if youre skilled calculate your own Q smaller than 0.5 (LR) as a 8-1...

Hi alex. Sure the 12 incher starts narrowing around 700. But the horn does too. And in that area you cross both at -6dB. which contributes to narrowing vertically. The magic is, to merge in a way that off axis its not getting too odd in a complex sum...
|
|
Hi panwitzResist the idiot-fashion of crossing too low. I recommend at least 1k for such Coral, 2nd order or higher. Also it gives nice lobing transition with the 12 inch (could even improve crossing 1.2 or 1.4). These biradial horns (i love the dept...

Hi Romy. You hit some point. But thats half obsolete. I shouldntve tried to gather the stuff for the VO copy. That visit to Klaus opened my eyes. I already switched my priorities a view times. From tonality, then resolution, to latest color (VO) but ...
|
|
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 ...

Hi everyone,Ive been tracking this exciting conversation for some days. One from outside may think this is weird, we are making a lot of air about some sound-description without getting to the point. Im (or was) normally more rational. And if I read ...

Hi Romy,
Again, good words (don't want to kiss your ass ;) ). Though, I get your point and agree, one should not think that this winter picture means Goto sound cold (u never know what one could read out of it) .
What Klaus also highlighted, is...
|

Hi Romy,I agree its a relief to hear finally someone describing something. Because all the mysterious dust around it makes one really curious :) And you cant hear them anywhere.So i got really "tensioned". Finally... and id like to share about it. As...

just to stress out: like live... Does not refer to a specific audiophile plastic three dimensional rendering only. It was so live, .... how to say... “alive” like you could throw a piece of meat to the speakers and one would believe that “it” will gr...

Hi everyone Guess what! Just had a visit to this system last night. Upfront, the owner - thank you Klaus again - is a very welcoming and friendly fellow. But also remarkably reasonable and decent. Total absence of any need to show off. You rather nee...

Its worth to know, seeking for advise, that majority of people want to recommend what they have/do/did.
Regardless of what it is, they want to tell you...

hi maxx
Just found this by accident. Had similar problems in my K-horn when i started to use it higher.
I found out that the 8 Liter prechamber caused the resonance in mine about an octave higher than you seem to have yours.
That...

Hi Romy. Interesting point as i had similar perception along my recent I ran an 8inch driver with fronthorn. Then just got my hands on a pair of RFT L-3701 (or 3702). http://tempuri.org/tempuri.htmlA fabulous driver with exactly those parameters. T...
|

hi RomyI don’t feel much friction with your response. Thats mostly fine. But I replied assuming such a question is raised by someone who has experienced DIY background and basics how to „design sound“.This is of course a precondition. Of course we ca...

you think humans can fly to the moon but no one can copy the VO?Kevin used some magic tricks and got them blessed by indian guru, applied star dust, and beyond physics? Or simply you didn’t listen to them yet or personally find it not worth?...
|
|
ah forgot. Have some measures to give you an idea. First, this is an (what i use as good budget replacement for the TAD2002 tweeter) a JBL LE85/ 2420 in that trumpet. Green is a „normal“ horn response for comparison. Red is the JBL 2312 trumpet: [url...

hi. That’s a nice topic. I studied the VO like a maniac. For me there are 3 topics. First was obvious, easy, the horns. The bass horn for the ak151 is housing a rear chamber slightly open, giving the injector channel - that creates a lot charme, flav...
|
|
hi Romy. Nice topic! I have a very nice memory. I started very young, supported by a friend who tought me a lot and gave me books to study. I learned the basic formulas and started DIY speakers from purely technical perspectives, graphs, math, calcul...
|
|
Hi Romy Im just trying to imagine that. If you got to keep the vertical offset small, between the ways, this would rip a hole in the middle, wouldnt it ? Also bit surprising as i thought you liked the injector on the ground initially. I hope I unde...
