[quote user="Jorge"] I dont expect any big changes on my system with them, but i want to be surprised![/quote] If you have a good 10’ driver then going with the same horn to 4” and 8” Fane will give you some advantage. You will pick up some EQ at low...

I have been running around this design for a couple of months...I re-designed it just now to change some numbers according to your post. The main idea is to have a lot of posibilities in a huge horn:It is formed by conical sectors th...

Since the 8M is now no longer to be had anywhere, for love or money (delighted to be contradicted on this), would people care to suggest alternatives for precisely the use Romy puts it to: driving a round, 3-4 inch throat, upper bass horn? I know it ...

[quote user="jessie.dazzle"]Do I understand correctly: AG used Fane 8Ms in the Trios upper bass horn?[/quote] Oh, no! AG in Trio’s upperbass horn used similar 8” driver with 103 sensitivity. That driver was bad and it made me to look for a replacemen...

JD,In the case of the mid-bass horn, the throat transition does not affect the sound enough to worry about IMO. Due to the narrow bandwidth (100Hz - 1000Hz) the step transition between the woofer cone and horn throat is acoustically invisible. I...

I've been having love/hate relationship with Lowther (and its siblings) for several years now. As you all say, it has many problems to use as a full-ranger. Right now, my set up is a 3way multi-amp, Lowther (Reps 1) in Medallion cabi...

[quote user="Ronnie"]The next big problem with sound here I think is a difference in sound level between upper bass and MF/HF.Upper bass seems louder (and ought to be). Would you help this electronics-handicapped guy to pad down the upper bass horn w...

Interesting. I wonder whether I actually did the Pussy- or Wilson positioning.I found 4 tiny hotspots around the whole room (for one specific vertical position). The boom areas were large (or perhaps there were many boom areas, close together?),...

I gave another run to Vitavox S2 with electromagnet and while I was listening I come across to an interesting observation. I screw the S3 in 330Hz horn and was trying to run it with 500Hz crossover point. It is pretty standard configuration, the way ...

This subject of digital crossovers became quite popular during last few years and many audio-people give up and go for a simplicity and painlessness of digital crossovering. There is an army of people out there who would swear by a complete transpare...

Here are some photos of Martin Sedon's 204Hz and 340Hz Le Cleac'h horns, which likely have more reasonable shipping charges and fit through doorways, etc. better than the 160Hz version. They have a T-factor (expansion rate) of T = 0.8, which was reco...

Hi Romy,
Well firstly on those, the tweeter is not offset to one side - it appears to be time aligned directly behind the midrange horn and upper bass unit. Secondly, that's a JBL 2405....

Jessie, there is another solution that you might consider, that might be viewed as compromise for one-side as might not be view is compromised from other side. If to allowed ourselves to close eyes to midbass timing-integration and if the geography o...

How did you determine that it is the horn. What makes you think that you can damp a horns mouth at 200 Hz. Have you never read what a room does to frequencies under 400 Hz? If not, check this site out: http://amroc.andymel.euMaxx, I think that you ar...

Herman, I am glad that you feel better about sound from your midbass horns. I do not know what damage digital amps incur but even your experience of hating the sound of those horns to falling in love with them just after changing the amp do suggests ...

[quote user="Jorge"]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, ma...

The Delta Pro-8B looks like a very fine driver, in fact on the paper it is even better then Fane (with exception of sensitivity and inductance) The problem is that no one knows how this driver will sound until it is loaded into a specific horn, no o...

I mean,
does anyone really expect to straight away come up with a "horn
profile" via math (or voodoo) and then just turn or cast it, bolt on
the driver and, voila?If we talking about upper-bass horn I think yes, via match.I reade...

Antonio,
Bruce Edgar sells an excellent all front-loading horn system, the Titan, which works well in small rooms. He will sell you unfinished horns, and you can find/buy the drivers yourself if you are a DIY guy, or on a budget. Considering the...
