Romy, i hope this post doesn't offend your sensibilities. I am not gonna say a word about the physics principles that have led me to the conclusion that this is something that should be tried ( unless you ask of course ).
The idea i have is...

[quote user="cdwitmer"]I'm probably revealing my ignorance by even asking this, but I'm curious to know if a field coil ribbon tweeter could be practical. It occurs to me that if one could be made, it would be a lot safer since it wouldn't be a black...

Hi,I am slowly building my own Macondo. I understand why the injection channel is there. It brings some kind of softness that the compression drivers lack. I am using a 12" JBL midbass driver (~100dB sensitivity) in a 50L single driver Marshall cabin...

when you say conventional tweeters have 30 - 40 degrees - at which frequency is that ? probably not at 20 khz.
sure at some low enough frequency a ribbon in effect becomes a point source. but at higher frequencies it should become more and more ...

Most here are probably familiar with the fact that A/B "blind tests" were popular in the early days of "audio", where listeners seemingly could not distinguish between live sounds and electronic "counterparts" issuing from behind a curtain. Today we...

[quote user="anthony"]I plan to
build a fullrange Melquiades for a friend and then if that works out the DSET 6
or 7 channel version for myself. [/quote]
That is very good approach in my view. The
problem is in this approach that you have t...

I have posted about some of my recent experience with longer "naked" HF ribbons in Romy's "Water Drop" thread. Here are some observations that relate these drivers back to the ML2s, along with some other recent ML2 trivia.My speakers are listed...

Do you remember in the brilliant cartoon “Ice Age” there was that lovely character who was going of his way in his infinite chase for the nut? I feel audio people have the sale obsession with ribbons, or more precisely with importer use it ribbons. R...

[quote user="drdna"] I am kind of disappointed, since you typically advocate a very careful and systematic way of proceeding. What do you mean by extremely different positive?[/quote]Well, I it what it is. I am not DIY-Moron and I do not do und...

i will give you this much - horn loading ribbons is fundamentally not as advantageous as horn loading dynamic drivers. this is because ribbon mass is already close to airload mass (in theory could even be less) and little extra efficiency can be ext...

Well Romy, IMO they are not just tonally different they are more
tonally correct, ie. they simply have less coloration than other
technologies. Just listen to a recording sometime made with a
ribbon microphone and you will understand what I ...

One funny thing about "dynamic range" is that different audio camps claim to desire and get some form of "improved" "dynamics" from their respective, widely differing topologies, from panels to single drivers, to plasma, etc.Maybe they don't claim to...

The new parts I needed to build the new crosovers arrived about a week ago, but I have been otherwise busy (for a change...), and now I've managed to get sick, so I am still only mentally toying with the project. I will try to work in some bread boar...

Romy, it sounds like, as usual, you have covered a lot of ground already before you put out your first questions about ribbons.FWIW, I presently use Arum Cantus G2Si ribbons, phasing them in at 10k Hz to supplement the Lowther DX4's dreaded...

Sometimes it can take a while for the other shoe to drop.I knew I had bass and balance issues with my phonostage. I recently added some capacitance to the output cap, and that did the trick for the ribbon level.Going back to the earlier discuss...

Here is another very interning solution to compliment S2 driver with top end. Townshend Audio have their Ribbon Tweeter with reported 110dB sensitivity and price of $1500.

Ok; there's a mis-print somewhere, or a manufacturing change... The web site linked listed SG-370 as 23,000 gauss, and SG-370DX as 24,000 gauss. The goto brochure lists SG-370 as 24,000 gauss. And was discussed yesterday w/ someone, one doesn't re...

Well, I still do not know what the tweeter solution would be. I know exactly what I want to get: to soften the S2 driver and get HF extension but without introducing HF noise. I know exactly how it should sound I juts do not know at this point how it...

Good luck getting midrange from F120A for non annoying monitors. Seems reasonable to expect, many people have been very happy with these drivers... I haven't tried this specific driver, but have spent some time trying to get a simila...

By looking at it this looks like a magnetostatic (isodynamic?) design rather than a ribbon. There's a Danish guy who has done good research on the subject: http://www.soundimage.dk/Different-col/Magneto.htm (you can click on "ribbon" for more in...

In my case I found that RAAL ribbon with first order can not deal with dynamics of S2 driver. [/quote]I suspect that my RAAL Lazy Ribbon does not have as much lower frequency output as your RAAL Waterdrop. RAAL refused...

[quote user="Jorge"]About the looks, well I listen to music with my eyes closed, so I dont really care.[/quote] Well, it is not how I see it. The topology of acoustic systems like Macondo implies the stand-alone tweeters. So, why do not make it attra...

"Sadurni Acoustics' Staccato 4-way hornspeaker exploits MDF horns with up to 3" wall thickness. The 92cm lower midrange horn which loads a cone driver can "achieve 100Hz in-room". The actual 'turbine-horn' midrange driver is a compression sort. "The ...

It is my understanding that the only reason to make a ribbon bigger is to get it to go lower in frequency. I don't know how Arum Cantus configures their G1, and I have not heard it so I cannot say if it is their "best" pure HF driver rather tha...

You raise an interesting point regarding ribbons but are missing the bigger picture.

[quote user="serenechaos"]Did you use LEAP or anything like that, or just cross everything over 1st order as a guess, and tune by ear? [/quote]
Oh, no. I do not use any LEAPs or others tools, no time domain analyses or anything like this – the...

During the 2002 CES, late at night, a friend of mine demonstrate me something that was tying to address for a few years. It was a very different “tone” form a loudspeaker or I would rather say a different relationship between reproduced and auditable...

I asked Alex who got those tweeter from him and he said that it was Stavros Danos from Cyprus. So, it was the Greek guy that we have meet before on the pages of my site:
