[quote user="haralanov"]Come ooon, comparison between the radiating area of direct radiator vs. the area of horn’s mouth is too amateurish even for some diyaudio.com level simpletons… It is as naïve as saying Leonardo’s Mona Lisa is simply 100 grams ...

Just to share with you with my ideas about the Scepter 500 clones. I´m not sure if I will use the w3801 bass drivers. I felt in love with Altec 416 and quite frankly I very much doubt that Onkyo would sound better or equally good. It surely doesn´t s...

Petar, I might have just been tired, but I thought I saw a pair of "likely" 3.5" paper tweeters, and I played the hypnotized consumer and bought them, to start with my adaption education. It might be a while before they get here, but in the meantime...

well i never thought i would be opening such a pandora's box with this combination.firstly,the drivers have the plastic surrounds(whew,lucky!i know the diaphragms are potentially harder to source than the drivers)what indicators or criteria would mak...

I do not know any advantages because the fact that the sound softer. I personally believe that the electromagnets have HIGHER MOMENTUM FLUX MODULATION and that make them to “sit” slightly… or exactly what I would like t...

[quote user="jweiss"] It was good to finally meet you at CES at the Cogent Room. I guess that you really found Steve and Rich's drivers pretty interesting (you initially wanted to buy a pair of the midrange drivers, remember?) [/quote]
Hi, Jonathan....

I wonder if anyone recognizes the drivers of the Cessaro Horn Acoustics? I thought that I know all of them but looking at Cessaro’s compression driver I have no idea what it is and I feel that my ego severally hurts. The pictures on the Cessaro site ...

[quote user="el`Ol"]I think they could could make the sound more pleasant with an overkill of second harmonic distortion. But for people who prefer that kind of sound a relax-horn like Anima would be better anyway. No real solution. Maybe they should...

I have recently been thinking about efficiency. Apart from enabling you to use low power amps, is there really any reason why high efficiency is better than low or medium efficiency, all else being equal (and I know perfectly well it never is, but le...

Romy, I do agree with all your comments. It is true that the magnitude of the rubber taste very much depends on the crossover frequency. I used them below 64Hz, but with first order filter, implemented before the amp that drives them. With that kind ...

[quote user="twogoodears"] Horns drivers from home listening are, must be differently built from industrial/P.A. drivers, period. [/quote] Yes and no. Yes, they might be, or even must be different, but can you elaborate on this idea in context of GOT...

Since the “no tilting rule” is one of the Macondo’s Axioms: (#2 - “All channels shell have strictly parallel axis”) then I would like to defend it.

I do not like the AMT Heil drivers at all. I have no idea what 5 times higher transient response they claimed but to my ears all AMT drivers I heard sounded like their upper notes are covered with 2 inch deep saliva. The Heil drivers are in my view t...

The AudioFederation guy posted pictures from RMAF show with Cogent room. (The images are courtesy to http://www.audiofederation.com)
I was wrong in my previous post, as Cogent did demonstrate their loudspeakers with Ionovac ion tweeter. Yester...

Paull, the horns might be “beautiful” but only themselves. When they are jointed with the rest Macondo spherical chennals then I do not like how it all looks together. Regarding the drivers, I do have a few options, I might slowly exercise them and ...

Hi audiofilofine.Nice drivers, although the picture is a bit fuzzy. Can you tell more about your drivers?Maurice....

I see that Eugenie’s installation did not create in people to think about it, I think it is unfortunate.
Here are some important points of Eugenie’s installation:
1) Use instead of good drivers a large amount of mediocre drivers. By do...

Which RCA driver you use? RCA had a few drivers the pre and after war. I am familiar with a few after war drivers that I tried in my 330Hz horn and I was not impressed. Reportedly the pre-war MI-1428B shall be the one to play with; I did not have thi...

I'm moving my two finished LF boxes (connected as 1 channel) around the room, trying to set them up to play more frequency-flat than I've been able to make them with only one box per channel.Putting one in the ceiling and the other on the floor, both...

[quote user="op.9"]Anyhow, what are the 2" comp drivers that ARE any good and are available comercially? I didnt go with any JBLs because I had a very bad time with the 2427 1" version, could never get any music out of it. [/quote]

Listening the argument of the field-coil’s people I note that they constantly stress the demagnetization subject of the driver’s magnet, advocating that with electromagnet “the field coil will always produce the same strength now and 100 years in the...

... so the new drivers, particularly the S2, may not be such a bad deal given the price of older drivers. The woofers would probably be less of a risk than the compression drivers, and at least new cones and bits and pieces are available. ...

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...
