BTW, I was not kidding about the dual-concentric 8” Fane. They did make a version of Studio 8M with a tweeter in the middle. I have it sitting in my driver storage…Another BTW: the tractrix curve was not introduced by Br...

I moved your post into a separate thread as I think your post about a subject, contrary to the thread where it was moved from was about the virgin fantasies… [quote user="Ronnie"] I thought I built almost copies of the Macondo upperbass horns, yet I'...

[quote user="Kcct82"] Hey guys, I bought the Goto 505TT with S150 horn brand new over 2 years ago. Guess what? I'd still be in sonic shit if I followed the 200-1000hz "recommendation". The 505TT does not perform well below 400hz and when I final...

Yes, I did not realize that the price of £225 is for a PAIR; usually price is given per driver. I guess the £225 per pair is not and of the world but I still insist to pay 65 cents per 1 Euro as it use to do… In past I n...

I do not think my topology is relevant, (it took me 3 months to get my studio horns to sound right 20 years ago so I expect this again, it is a mix of mjlouspeaker transmission lines and this midrange m4 trial. And it is actually 2 systems I am w...

[quote user="ayebee"] The horns that Stereo Lab make are very good, especially considering the relatively modest prices. I bought the "Ultra-Fi" version of the 140Hz horns and they are of course not completely free of resonance ….Present system consi...

[quote user="jessie.dazzle"] If you've tried both, and decided to keep the 16R versions, you've answered a question I've had for quite a while; I too use the 16R version, but have always wanted to try a pair of 8Ms with 8 Ohm coils (should have o...

[quote user="danvprod"]My objective is to create a system that is able to emotionally re-create music in a powerful and realistic way. My greatest memories are playing in orchestras and sitting in the middle of the violin section with a hundred o...

[quote user="oxric"] As to why people are interested in the 16 ohms drivers, that is only true of some. The idea is that if the Vitavox S2s are being used, and a single amplifier to drive the different channels, it seems to make sense to go for 1...

[quote user="TonyB"] So do your horns have 115Hz flare frequency? (and have the rear chamber tuned for 115Hz as well) [/quote]
They are 35”. Do your math. The back chamber tuned at 115Hz.
[quote user="TonyB"] From the pictures the horns look like t...

Someone contacted me earlier and expressed an interest in three pairs of Fane 8M drivers. After Romy posted his comments above, this person came back to let me know that Romy might be right and he would rather not rush into it. I have...

My current speakers are Edgarhorns with the straight 80hz upper-bass shell. The bass never sounded correct to me. The problems with Edgar's mid-bass are well documented at this site and elsewhere. I tried some simple modifications to the crossover...

[quote user="Romy the Cat"]Tax,
do not go over yourself with “building paranoia”, looking for drivers, horns, boxes and etc. If you are looking for 80Hz to 200Hz range (you will need higher upper knee for AG Dou) then you do not need a bass d...

Ulf, are you still around?
I would be interested in an update on this project.. are you listening to this setup a year later?
I have a pair of these same drivers (TAD tm-1201) sitting new in boxes and trying to determine what horn profile, tractr...

[quote user="jessie.dazzle"] What really surprised me was how good everything sounded with no filter on the upper-bass horns, and all drivers connected to the same (8 Ohm) tap; sure I'm getting too much mid-range from the upper-bass horn, but its...

[quote user="Romy the Cat"] Make an experiment, and I will simplify the case quite assertively. Take a typical compression driver, cross it at 800Hz, second order and load it into a proper contemporary horn (Tratrix or JMLC) of 300Hz. Listen that hor...

[quote user="Tax"] Your post has had the desired effect and I am doing some more research into Fane Studio 8M, 16 Ohm drivers in a 4 inch throated horn tuned to 115Hz with the intention of crossing it from 70Hz to 500Hz . This may be similar to w...

As can be seen in above photos, the front chamber is in reality "chamber of horrors" with highly polished surface interior, and look at the phase plug, after disassembly, I put it back together, and how can you align it? All that holds it togethe...

Ok, since you people stop to drop the euphoric saliva around the Goto subject I think it would be worth to outline my interest in Goto. Not only worth but I kind of feel an obligation. I feel that my site surprisingly has become a resource that ...

[quote user="Romy the Cat"]
...this interesting point has no practical answer. First of all in the case of Rakesh horn what N-Set proposed is not necessary. Those 115Hz Hasqiun-style horns that Rakesh emulates are well dumped with own mass and own ...

[quote user="ulf"]One advantage of the use of a phase plug in a midbass horn is that it will beam less at higher frequenzies than a horn without phase plug. If the phase plug is designed for the specific horn and driver it will help "steer" the HF.

Luc,
I am not ‘lucfm’ and I hope he will reply to you but I would like to pass some of my observation that you might find useful.
In my past when I discovered Fane Studio 8M I went over a number of 5-8 inches. At that time I used AG’s Trio upperb...

[quote user="ulf"]A few years ago we discovered the tractrix horn for MF use. It was really the most important improvement so far. No more honking exponential horn sound. The improvement was so clear that A/B testing was not needed. [/quote]

user="noviygera"]Also you say: "In reality the driver is the

Need I select a size? Or driver with certain spec? For example lets say driver

[quote user="anthony"]Romy, I
appreciate that this is an old thread now and that you may not remember
everything from your time developing these amplifiers, but I have a (hopefully)
simple question about the upperbass crossover in the schematic ab...

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...

This was the most astonishing and bewildering moment of my
entire audio life. It was in 2000. That time I lived in cozy downtown Boston
apartment that I absolutely loved. The apartment sounded fabulously with pretty
much any playback you put in. A...
