These are very interesting effects, all right. No way to be sure, I supppose, but if I understand you correctly this could be related to what I was calling the "MF attack" phenomenon, up the page. Although the ai...

I have tried both SS and tubed PP with HF ribbons, but not until ML2s have I gotten the "calm HF" I wanted from the ribbons. I am still experimenting with the Audaphons, but they seem to do best from 4 Ohm tap. My little 2A3 SETs did...

Romy, I am on the verge of an L-pad for my HF ribbons, but in my case I believe it is mostly the MC cartridge response I am wanting to offset, on a case by case basis.Also, this would allow me to adapt HF to recordings, since there are some...

[quote user="Paul S"] As a certified non-expert I wonder about 1st order XO with the tweeter, because of the phase issue. Probably stupid, but I always figured that at 180 degrees you could just switch the wires... Do I remember reading somewhe...

I am glad to hear that I am not the only one who is overwhelmed by compression drivers. I tried the A7s way back when they were current and everyone's favorite, and I tried various modifications with like-minded friends; but I came to the concl...

It is interesting indeed how people allow their attention to go from fixation to fixation without ever changing/adapting methodology, believing none the less that each single idea in turn is The Answer. I remember the first time I heard th...

Folks,It is really amusing. Here I am busy myself for a while and am not looking and suddenly Roman talks about Mini Monitors and secondar phonostages.It is even funnier if you realise taht I am on a similar kick right now, simply because I am workin...

Ronny, it does sound interesting, thanks. As they said they were the people who supplied the Red Rose Music speakers with Ribbons? Still, while they called a statement” "Ribbons are excellent but suffer from bad efficiency" as an warranted myth they ...

Hm, SGSG-37FRP, Driver frequency band: 400Hz - 10kHz, 18,500 gauss SG-370, Driver frequency band: 400Hz - 18kHz, 23,000 gauss SG-370DX, Driver frequency band: 400Hz - 20kHz, 24,000 gauss Inversing, they build up magnetic density and extend HF. I...

[quote user="Paul S"]For the Reps I will use a 2,200 Hz notch filter for its peak[/quote]Paul, why don’t you try to fix the problem of the Reps driver instead of notching it? There is a reason for the peak and I do not consider the problem could be s...

Thanks for your quick reply. I have been to assistance audio`s website, however was unable to find such model, but is possible they just disassembled the tweeter or whatever.This is really interesting news, about their violin reproduction, me too wou...

[quote user="el`Ol"] I am not ideologic, and if a driver that can be used from 1kHz up is only state of the art from 5kHz up I won´t hesitate to cross it there. [/quote]
There is a difference between “can be used from 1kHz” and “a driver sound at 1k...

You do not have a single capacitor on that ribbon as your
cap acts as a second order filter along with the ribbon built in transformer.
You might want to push the ribbon further then 12per octave that you have. I might
not do it if you are “satisf...

[quote user="morricab"] 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 resona...

That's one big tweeter, Romy, and, typically, it was made that big only because they intended for it to go low. I keep wondering about the effects of the extra mass, if nothing else, but also about dispersion and window blind effects ...

Nice job of keeping R off the ribbon. Like you said, who cares about circuit "damping" there, anyway, given the freaking magnet in that thing versus the 0 weight of the ribbon. I'd say it's "damped enough"...It will be interesting to...

[quote user="Paul S"] Speaking of "blowing", I have also made the fatal-to-the-ribbon mistake of trying to gently blow a speck of dust off one of them. Don't try this at home![/quote]
[quote user="Paul S"]No doubt …. there's still likely to be...

[quote user="Paul S"]Do you actually prefer the S2 at crossover frequencies, or is the problem driver compatibility, or is it just too much sound at crossover? If you have the power to burn, why not scrub a dB or two off the ribbon, or ju...

My preferred type of speaker is a full range ribbon, though I've always had a monkey/Tannoy on my back which is surprising as I don't really care for box speakers. I've heard many over the years but I was never really that impressed but wan...

That is one good looking ribbon driver.It almost looks like an ideal solution. Sure looks smarter than other ribbons....

[quote user="Vasyachkin"]waveguides as far as i can tell are designed to equalize the power response.
for example if we are talking about a typical 2-way speaker with a 7" midbass and 1" tweeter then there will be a discontinuity in the power respo...

I`ve had many small ribbons in my system over the years and I don`t like them. True, they are without competiton above a few Khz, but how to find a decent partnering midrange? They represent unnecessary fragmenting of the musical spectrum (a typical ...

I am not quite sure why Paul came up in this thread with the subject of “ribbons sensitivity to... everything”. That is absolutely not relevant to the AHFS concept. el`Ol, the ribbons and AMT tweeter I feel absolutely identically wrong if to approach...

I note English Mfgrs tried low power ribbon Midrange horns in the 50's (Decca, Kelly & Quad also made one!).These were probably inspired by the hi pwr prewar? Klangfilm ribbon horn (would like to hear one of those!) But, after Peter Walker moved ...

Haralanov, let me know if you actually have something, otherwise I will continue with the Audaphon ribbon for the first round of the downward-pitching exercise. On the one hand, I wish I'd kept the Peerless 2" paper tweeters I had; on the other hand,...

Yes, a cheap inductive l-pad between OPT and S2 in midrange channel. Interestingly, the frequency response of the first order Lazy Ribbon is remarkably similar to a response you posted somewhere on this site of the Water Drop with third order filter...

[quote user="Romy the Cat"] That is very good approach in my view. The
problem is in this approach that you have to have high sensitively speakers
that you would be able to use with that test full-range Milq. The behavior of
the Full range Milq wi...
