I am on begining (1 week in progress) to design frame for my future horns. 115hz400hz ribbonand 200hz or direct radiator as fundamental channel.I like functionality of Jessie frame, and Romy "flying horns" look.I think my project will be ready at th...

OK, the Reps is so up-tilted that I cannot deal with it stock without a BH. So, back to the DX4, because I can't tie the ribbon on the Reps' tail. I have re-entered Crossover Hell. Programs and math up the wazoo. More, anon.Paul S...

Sounds as though you had a wonderful time. The Brinkmann room alternated between three tables, their 'La grange ' direct drive 'Oasis' and a balace with a 'Thales' tonearm, the Verity's use a ribbon tweeter Raal? Which in that undamped room was just ...

Crossovers are so annoying, about impossible to nail down, and it's almost as though the more you study the problem, the fuzzier the "answer" gets.For now, I would like to more or less forget about "phase" considerations, partly in order to get this ...

Hello chaps,
Another option thrown in there by Bud; always enjoy your posts even if I don't follow them 100%...Let me attempt to barbarically distil what you said into 2 aspects which are
1) The dielectric properties of the insulating materials2) M...

Nine years ago, when I posted the initial post in this
thread the Aries Cerat was a different company with different products.
As I understand in 2014 they changed a lot and today they have a speaker that I
would like to talk a little: Aries Cera...

So, you are thinking about 3-way installation with GOTO bass, Lowther mid range and some ribbon atop? It is certainly no one knows how I might end up: try it, post the pictures and let know us how it went.
I can see a few points where you might need...

[quote user="Jorge"]I tend to think that we are not copying Romy, but more that he has generated a school of thought on audio and yes horns speakers also.I too have a system following some of the Macondo Axioms, but have used all diferent drivers.As ...

Once again, it is not about the loudspeakers but about the idiots who put themselves in position of shaping public opinion by expressing the “expert” view. Yes, I am taking about the Morons who write those audio reviews. A new Danish 90db sensi...

Hi Kitty,This combo is quite interesting and amazingly coincidental....I had scan speak 18W's sitting around from my old speakers and just recently had them put in sealed boxes. I was using a Seas silk dome on top (in free a...

Bob,
Yes, the variants are multiple but the key I feel might be the following: smaller size, less reliance to baffled, smaller size. Or yes, did I mention the smaller size?
The thing that led me to think about the MiniMe incorporation was my recent...

Romy, my weekend is excellent, truly excellent. I was sitting at the cricket watching my son play this morning and I had one of those "eureka" moments. I realised that when paralleled, the DC resistance of the voice coils (as measured) reduced and ...

Yes. I used "qualities" in the Greek sense (Qualia), which I think is pretty close to your Romyism, "perceptional events". And there is the "pre-attack" corollary, where one somehow senses the presence/gathering force of th...

Adrian, I have alternately revelled in and anguished over this for some time now, the lynch pin for me being the electricity. Yes, I can generally hear any change I make to the system, but it is consistently the quality of the electricity that ...

Hi Romy,I knew that would be your response! It's definitely a case of (1) or (2) though. If he had been upfront about them being new, and not that he found them in a cinema, that would have been another matter. Also, I believe Mike Harvey owns the ri...

[quote user="Paul S"]By far the most promising planar speakers I've heard have been the giant Sound Lab models. These use an assortment of variously-sized "tuned" planes comprising one larger, "curved" plane. However, ...

Pretty clean, Romy (and one hellova tranny at Fundamentals)!Of course, I have questions:I thought you said Vishay metal foils in your earlier response about bias adjustment?If so does that mean steps, or... how, exactly?When you specify "Full" ...

#3 reminds me of the HF-only naked ribbon, which seems to be the only exception, able to do this through a series cap.If you have the Mercury SR2-9013 35mm master Dorati/LSO Nutcracker, that might be a treat (if you can still do the Nutcrac...

Since I went single-stage Milq with output transformer on the Water Drop’s side I am witnessing an interesting phenomenon. When the amp is cold and juts tuned on then during the first 3-5 minutes (in addtion to the 2.5 minutes of start up procedures)...

[quote user="Paul S"]OK, Romy, that EnABL stuff got my attention!I can't recall all of the bad ideas borne of good research, but this EnABL thing sounds a little fishy, and certainly it sounds too good to be true, as existing in a simple and really u...

[quote user="Paul S"] 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; b...

AlohaWell, Martin does this as a labour of love, it's not his day job. They are fibreglass, and once he has constructed the mould, the manufacture is fairly straightforward, unlike say JLH's devices.So you are not paying for audiophile...

Hi, Marcus
As I understand it is 15” loaded into 110-150Hz horn, MF compression driver in 350-400Hz horn, Ribbon tweeter and a pair of tapped horns? Looks good.
If it were up to me than I would paint the entire baffle with tweeter and MF i...

[quote user="Vasyachkin"]the only real questionable aspect here is adding a second set of back firing, inverted phase horns. mathematically speaking it is what the design "needs" but of course the real question is - what does it sound like ? that's...
|

The ribbons surely do lack "qualities", but we are talking about serious "HF" in this case, and who says real HF actually wants "qualities"? I really doubt that any "tweeter" that can do "stuff" can also do what the ribbon does best - in a class...
|
|
What do you mean “I have been against this on principle”? I do use a cap and coil on ribbon and I do not see that they might be changing over time. My idea of trying to get rid of the Milq’s output stage has nothing to do with “HF alternative”. ...

[quote user="Vasyachkin"] 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 ex...

In theory wideband electronics with very gentle HF slopes are optimal. In practice I have never liked them. For the same reason I detest the 6922 tube vs the 12A series tubes or most less well known. As Romy notes, linearity and measurements in this ...
