[quote user="Paul S"]First, I just have to ask: What are the odds that the same AA guy I just referred to obliquely in my previous post turns up immediately thereafter?[/quote]pretty good since he's the only guy who talks about them?[quote ...

Romy:Thank you for your response. You are correct that the vision is not completely developed for this 4 way. A bit more info is needed. I've had some experience with JBL woofers, but am relying heavily on the results achieved...

I just found this thread and can comment on the Enabled DX4s. Limono (Wojtek) very gratiously loaned his Enabled 8 ohm Lowther DX4 drivers to me this past summer (summer of 2008). It took my a while to make the crossover for these (I have...

[quote user="ayebee"]If you look at the original Bionor drawings (you can find them at klangfilm.free.fr) you see that the "bass" horn is actually made out of two sections, the outer is curved, the inner is conical and expand both horizontally and la...

[quote user="Romy the Cat"]Anyhow, I did the measurements today and what I saw shocked me. Of the ULF sections has nice 20Hz at MF level then they have +12dB at 60Hz level. That explains everything but it also absolutely clearly indicates that the se...

[quote user="Scott L"]I had to take
pause before I answered here; realizing in an almost shocking manner [that] I
don't listen to many commercial loudspeakers.
I am largely involved in the (gasp) DIY
community, where it's also very often done inc...

(sorry, this is supposed to be posted in the questions and answers colume but I must be so stupid to have it posted here and now I don't know how to move it there.)Hi Romy,How are you! This is Welborne, from far across the ocean, Hong Kong. I have k...

It looks like Jeffrey Jackson formed a new company and along
with his friends makes a new horn-loaded products. http://www.wheel-fi.com/
….and do not miss the video.

Welll, I know very little about what th...

Romy, yes it is an interesting subject and one that I have thought quite a bit about although not directly from the angle from which you are approaching it.One of Macondos great strengths is narrow directivity from high frequencies all the way down t...

The “best midrange comes from compression drivers”. I see somebody like Haralanov would be very much opposed to this comment. The irony is that I would be opposed as well to this comment. I would say that the best midrange at over 107dB sensitiv...

In the linked there above “Barn Conversion - James' Project” I have expressed my attitude toward low frequency bass. I certainly not “against” bass horn it but have “concerns”. The “open bottom” concept that I invented for myself is always make me to...

Well, the points you bring up are valid but as anything else it all highlight problems with people not with equipment. I am not sure that I am glad with my decisiveness and sanity in MiniMe projects. I was trying to rationalize the MiniMe idea in the...

Please, have some fun. First download the white paper to see what the patent artists came up with. It is essentially correct but not to scale.
Note that it requires 18 offset sets of blocks around the periphery of a cone. About two degrees of space ...

I’ve been harassing my horn-maker for quite a while with an idea to go for straight, no-cheating 45-50Hx horn. We discussed it countless times and sometime probably we would go for this, and particularly if I figure out how to resolve the delays prob...

I recently spoke with Paul Eizik regarding the criticality of the open-air mounting of that driver instead of baffle-mounting. I decided to go extreme and to get rid of that plate that I had under the driver no mater now small it was, also I thought ...

Hi Romy,I have found that the Apogee loudspeakers ribbon drivers can quite successfully reproduce correct tone. The reason why is this: They have very little coloration from the driver materials themselves (no nasty resonances as the reso...

Actually it is very interesting question and I almost feel you pain for decision you will be making. I do not think that anyone would be able to express any arbitral opinion about the subject, as least an opinion that worth to follow. You see, buildi...

I've been thinking abut this question form several angles. Firstly practical.I thought I'd better see what low bass sounds like. And to get some idea of placement possibilities. So I set up my LS3/5as in the (rather cold) un-converted barn. Couldn't ...

A visitor of my site, a guy who never ask stupid question about audio, asked me a question how to find a correct size of the back chamber of a straight upper bass horn that he juts built. I wrote a reply but then realized that it would be worth to up...

I think you’re onto something in it. Those Lowthers in fact might be not unfavorable candidates to use with horns at all. An open baffle at 150Hz? Perhaps, although I do not feel that Lowther can handle that exertion with a necessary integrity,...

[quote user="Paul S"] I never managed to come up with a horn that did not sound like a horn… [/quote]
As many times I heard similar comments as many times I feel that people rather demonstrate own foolishness on the subject then express a sane...

I visitor of my site shat me an email informing that that above depicted horn installation by Marc Henri and Andre Klein was made French Musique-Concrete company. I do not know a lot about those people, beside that they hand around Jean Michel Le Clé...

The reason that I built the 6C33C preamp was to explore the 6C33C true musical potential like I did with the 845. Not only did I compare the sound of these tubes in power amp, but also in preamp. The reason is that with power amp you might hit some l...

Romy,
No, the DAC was not set at maximum level (for best sound) while Cyrille listening to the system. It was set at normal volume for the whole system. When Cyrille dropped by, I was showing him the Field Coil open baffle speaker system which con...

The Western Electric L-9 in Munich was/is an infinite baffle design. The 754B woofers are in a sealed enclosure with a front horn. There is no possibility of cancellation between front wave and back wave of speaker, so I wouldn't call it an "open baf...

Today I had a promising experience. Bill is keep experimenting with his Dannoys and I was visiting him to see what's going on there, since I am still waiting for my panels and I can experience the Dannoy foreplay only valceruasly. We did a very usefu...

It looks to me that I will be able to live with my 6 driver
line array. Again no measurements were made but it is what it “looks”. Sound-wise it is very reputable and I just might
leave it as is. My current room is 6 larger to what I had in downto...

It took for me a few weeks
to put up a new direct radiator Midbass channels. Each channel has 2 of Vitavox
15/40 drivers is seals 2 cu foot enclosures. No filtration of any kind on
speaker level and Vitavoxes juts are driver from Milq LF channel t...
