Hi Vitavox fans...
Thought this might be of interest - these are 160Hz 1.5" throat that Martin Seddon is making for me. The mounting flange isn't moulded on yet and the interior finish is alabaster like rather than glossy. I intend to damp the ...

I might also be interested and am in the UK. Any rough idea of price?rgsGuy...

Hope Romy won't mind a semi-commercial update...Martin will be selling these for AUD$ 1140, which is about $860 at current rates. He will have a website soon.Any more takers from the UK?Best,cv...

.... available bass horns are the same to me and I customary discard them. I also care less about the price: I am talking about an interesting horn design but not about an interesting product to buy. The beryllium cones - yes I do not like them in TA...

This seems like an appropriate place to share my latest thoughts about Macondo copying!I thought I built almost copies of the Macondo upperbass horns, yet I've really only achieved quite questionable results. Impressive from time to time, but never f...

Oh well.. I'd really like to save the horns. I appreciate your offer to help out!Still no measurements, but this can start the trouble shooting...CONSTRUCTIONFirst I refreshed my memory of exactly what I built. They certainly are far from being copie...

Hi James,
Theoretically a straight 33 feet long mono subhorn with the drivers at one end of the room and the mouth exiting the floor at the other end would probably cover from 10Hz to 30Hz with no problem, with the apropriate drivers.
I don't hav...

[quote user="Romy the Cat"]I stepped away from the idea of horn tweeters. A horn is equalization devise that boost lower knee. If people need to spread a tweeter in MF then it is OK but in my case my tweeter sits at 12.5K and I do not need any gain a...

Hello Romy and everyone, I am going to order a pair of 400Hz/1" tractrix horns from http://www.stereo-lab.de/tractrix.html to replace/compare with a pair of 500Hz TAD-like square mouth horns. These are to be used initially with the drivers that ...

There are more efficient drivers available, if that matters. As Romy pointed out, usually very different systems are used in PA and in homes. I thought you were talking about a Front Loaded Horn, not a Compound horn. "using the...

Adrian,
If you are still in MF frustrations then I have something that you might find interesting. Recently I pick up in UK a pair of Vitavox S3 drivers. They out to be with original metal cones. I do not need them but the price was too good to let ...

It sucks – whoever builds horns too damn far! I need to see my congressmen to lobby lowering taxes for horn users of something like this….
Anyhow, the “erenechaos” comments about the “soft bass" is a good sign, though of course to equalize the...

I bought those tweeters for Be Yamamura (second hand from Paul at Wembly Loudspeakers, in London) I also took Be to Heathrow Airport to take a plane to Brazil to install one of his truly superb VT4c stereo amps! It was the morning of a great wind ...

Here is another installation where midbass horns are ceiling-mounted. The solution is very elegant but I do not completely agree with it. One of the rules of the game is that lower frequencies shall not be radiated from the space between higher frequ...

I had exactly the same thought...They're "elliptical JMLC" horns by autotech.pl. There are some threads on diyaudio, including:http://www.diyaudio.com/forums/group-buys/166312-waveguides-horns.htmland they have a website showing their myriad options ...

Hi Romy. Have you tried a large cone high efficiency tweeter? I have used a Saba 4 inch diameter 'green cone' 99 dB/w without a horn and found it to be interesting. Have you tried some kind of horn loading with such a tweeter? Steve...

Nice posts Romy and Jan, agree almost 100%. I've heard the Behringer in an originally crummy system and it butchered things completely. The input levels were low, which as you point out, won't have helped at all.On a vaguely related note: I dunno if ...

Well, I have a theory that the rough surface may be helping to attenuate multiple back-forth axial reflections, but from what you say, it may be that it results in - what's the proper term? - irregular as opposed to laminar flow at the surf...
