So, with this horn I got the sound I was dreaming for!Currently system consists of 4 channels:1. RAAL Lazy Ribbon (14k+)2. JBL 2453 in 550Hz LeCleach (1200 - 14k)3. JBL 2490 in first part of own JBL horn (300-1200)4. 12" Supravox in 42Hz 2m long horn...

Guest napping now from 16 hrs jet lag, so I have a moment...Jorge, you raise an interesting point about THs. I may be incorrect in assuming THs sound worse as they play higher in freq. Perhaps instead the limitation is one of narrow bandwidth rathe...

I think the usage of Romys Injection Channel has misguided you to think it was implemented because of a certian lack of tone or some sterile sound, nothing of the sort, I cannot blame you for not having listened to Romys system, but theo...

I'm also concerned about the range, but I believe that in using an appropriate driver, I may be able to achieve a target range of 40Hz to 400Hz.One reason for my wanting to achieve this range is precisely for the purpose of not wanting to have a 4-Wa...

Had a wonderful visit with my Japanese friend. But now she's flying West over the Pacific, and I wanted to add my experience to the TH discussion.The main benefit of the TH is the relatively small mouth compared with a traditional horn. That's all....

[quote user="jessie.dazzle"] Back when Fane were still in business, I ordered a pair in 16O (I don't know if there is a theoretical best choice between the two for horn loading... Any thoughts ? However, the 8O model will require a smaller coil in th...

Since you are now an "insider" and saw these speakers in vivo. What is the mid-bass horn (as Romy notes) & that small upper mid. Anything else?You know it's unlikely that many (any?) of us will make to Munich Hi-End......

Hello Romy,The music links don't work for me. They're pointing at http://localhost/...?I'd love to hear some music.Been up all night stirring up the second upper bass horn. Halfway done. =)/Ronnie...

[quote user="CO"] I dont need flat to 20K but dropping after 10K necesetates a tweeter. [/quote]
And there is nothing wrong with it. No one 500Hz driver that said is doing to 20K in reality does it. In fact if a driver goes to 20K then the place for...

Thanks, Greg. I will consider it. Perhaps I should even model on my upper bass horn and see what I might get out of it. The Cat...

Paul,I'm with you waiting for a bit more enlightenment and less rhetoric on the subject. As you stated if e.g. a Bass reflex does certain things wrong there are some known 'recipes' / fixes to try, and some will work. We would want to utilize a u...

Romy,you did not disappoint my expectation in your reply. Who can argue with the take: "bugger off and do some home-work"? On the other hand, when looking through that "Knowledge tree TM" it's more of a "forest" as far as horns are concerned. So it's...

Merry Christmas!Nice woodworking job on your speakers.I have a couple if questions:Why did you select the drivers that you did?What made you select one horn for the midrange but for nothing else?What process did you use to select the crossover points...

Romy,
It's good to have all this info in one post.
Regarding N° 5 :
"5) Horns shell have a sufficient mass properly projected to a given channel’s LF boundary and the horn’s mass should be properly distributed within a horn."
I have seen a lo...

Andrew,Dont buy all the drivers at once, I would get only the upper bass horn drivers and maybe the mid drivers, you will have to play around with these for a while before things start clicking toghether, by then who knows, maybe you will think t...

Haralanov, it had to say, I think it would be all depends how he use that MF driver. Do not forget that this MF driver, I still insist to call it Lowther has very extended HF. That is different type of HF that is coming from “cigarette filter paper”....

Very good, thanks for the images. It would be very interning to learn what the bandwidth of the horns, the bandwidth of the drivers and the specificity of crossovers you eventually chose to use with each channel. It might take for you for a while to ...

I'm a new reader of your website and one subject which interests me a lot is that of upper bass horns.As you have noted time and again (with which I agree almost completely, after reading a lot of 'research' [many claiming to defy the laws of physics...

Another bogus idea.If a perfect upper bass could be achieved by means of spherical (approx. 1m diameter horn), what would be the next acceptable solution,if space considerations do not allow big horns? Perhaps that could be a line array of small dire...

Hi Roberts, Romy and others,Before this thread vanishes in undeserved obscurity, I have a question or two for you. I understand that the issue is a complex one and should be addressed with more care and paying attention to detail than I am do...

Romy,
Sorry for taking so long to get back to you… (this being the summer time in a Latin country, I still have no internet connection at the new place).
Quote from Romy “If your lower bass channels run from 40Hz and down then the PS, size of the c...

[quote user="skushino"] I think you are saying the effects of my room may be dominating any problems with the Edgarhorn bass, or at least I can't know since I don't have any objective data. Is this correct?
Maybe you're right. But here is wh...

I’m new to this outstanding website and I found it has really educational value and antimoronizating information :)
I’m still in the world of direct radiators and I’m looking for the ultimate midbass channel solution. At this time it’s still impossi...

[quote user="pe1mmk"]Well Cat you can call me whatever you like, but you still did not answer my question. Both have a horn for highs, for mids and for lows, only the sub lows are handled differently. [/quote]
I do not think I called you with names...

Hello Romy,
My apologies for not getting back to you sooner… Moving to the new place has turned out to be a huge task, but worth it, as this new home actually has a place to work, not to mention a much better selection of recorded music at the local...

Now I have been listening the different crossovers trying to shape the new Macondo general balance. This is so fascinating ceremony that I do have a lot of fan. The things doing alone very well. I boosted upper bass and it worked now very-very well....
