[quote user="N-set"] Romy would you care to elaborate on that a bit? In particular have you hear amorphous/silver combination?[/quote] Nope I never had it and even f I did it would be difficult to generalize anything. I had only once a fully silver...

Well, I do have 3 channels of DSEP. Dedicated Single Ended Pentode: one channel (bass/mid 30-500 Hz) with a 307A DH pentode feeding two wonderful Fane neodymium Colossus 12" - one from FS to 150 Hz and the second from FS to 500 Hz. OPT with a lot of ...

Hm, the example with Wilson is much more complicated then you think. Wilson are very much misunderstood and mis-presented products. From certain prospective they well worth their money. Still, in context of this thread: problem with Wilson is not Wil...

Hmmm... Thorny, difficult topic...The "integration" of HF certainly involves its "disappearance" - as "HF", as such - "into the soundfield". At the very least, Tone ultimately depends on this. But there also appear to be other benefits from "ge...

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...

[quote user="Romy the Cat"]Indeed, I did not realized that I shifted my thinking in this thread and an in my general views from the ways of using those “Resonating Oops” to the subject of Injection principles. I think I did it because Injection, as I...

First of all it was quite interesting and quite educational. Second of all it answers no questions but rather creates more questions. Here is what I try to compile some my observations and thoughts on the subject.
I have a local guy who red my site ...

If one dht is good, two must be better?
I don't know. Some people like combining 6C45 etc with DHT, supposedly mixing the appealing qualities of each. Other people find that using a 6C45 (or other high-gm tube) with a 300B just makes a 300B sound...

Romy, Now you mention the issues here, I am thinking about what the differences in quality might be due to. I notice that you haven't explicitly said which is better, super or regular... so think of this just as brainstorming as to why things are... ...

You and I now have what seems to be very similar situations; similar MF and HF channels, in a room of similar size. However, I still have no operational dedicated mid-bass channels; you do. I have dedicated lower-bass channels; you do not. As is ...

[quote user="el`Ol"]A $$$ solution for a bass array that comes into my mind are the sandwich cone drivers from Accuton.Monstrous neodymium magnet, underhung voice coil (for low flux modulation).Very low Fs.Relatively low QMS for use in sealed enclosu...

Looking at Paul keep barking at the APS "success" I become to think what would constitute success in electricity battle. From one side the sonic result that PP2000 demonstrates is an indication that he battle is over. Is it? Sure the PP2000 as a devi...

to be clear:
i do have some expectation that 'my final solution' will consist of dedicated amplification per driver in a substantially horn loaded arrangement. I have some expectation that amplification will be single ended and quite likely have a b...

Greg, do you have any experience with the Eminence drivers?When the Audax PR380M2 I use (8 Ohm) became unavailable, Dick Osher specified the 15" Eminence driver as a drop-in substitute for the BZ series.I happen to use a single 15 " Au...

Well, spent a few more hours to listening Avicenna. Although it has much better sound then from the wall but there are a lot of moments in this sound that I do not like. It is kind of freakish and demoralizing as Avicenna feeds system with absolutely...

[quote user="op.9"]I now run my 'tweeter' amp 1st order high pass at 2200hz (driving BMS 4540nd in 1500hz leCleach horn) so my impressions might have some bearing on Romy's new amps. I was playing around with operating points and components in my sin...

[quote user="cv"]Romy,Are you currently implementing "nominal" 3200Hz x/o on the mid range channel S2 using a cap at the driver? I know this works nicely to ameliorate the "secondary" resonance of the plastic edged diaphragm.Reason I ask is because t...

I was thinking about the subject for a long time. People in audio love to make generalization, so do I, but in it is not so simple. People attribute to output tubes some “special” qualities but I more interested not about unnecessary drooling about A...

One of the problems with horns is the inflexibility of frequency cut-off: you are limited to a discrete number equal to the number of horns you have. This makes experimentation difficult without having an absurdly large array of different hor...

Probably not one subject among horn enthusiasts does not arouse as much fantasies as midbass horns. This subject in one way or another was discussed at my site (look for the linked threads) but I would light look at the subject of the Midbass ho...

Fostex T 500A MK 2 Horn Super TweeterArticle By Bill Gaw at www.enjoythemusic.com
As most of you know by now, I'm a horny type of guy. While my wife may dispute this, my audio system (actually my second partner) would have to agree as all seven spea...

Joe, I do appreciate that that invitation is open-ended and I might take advantage of it sometimes. Frankly I do not feel any specific temptations that I need to “drop everything” and to run to another side of the globe to audition the Silbatone. The...

I am not a huge fun of S3 for MF use as the ceramic magnet is less interesting then alnico magnet for HF applications. For the low mid, or as I call it the Fundamental Channels the HF problem that ceramic has do not manifest themselves. My Fundamenta...

Teodor, there is nothing to ask excuses for. You do what you do and it shell be absolutely irrelevant to you what others think. There are no forbidden topics in this forum. It is not about being forbidden or following some kind multi-channel religion...

In one idealistic configuration I envisaged for myself, for a situation where cost and practicality no object, the basic room shape was pentagonal, with the facets ot the pentagon curved inwards to eliminate parallel reflecting surfaces and simultane...

[quote user="haralanov"] Some time ago I also thought my upper bass channel is flawlessly integrated, but when I added another, symmetrically arranged UB driver (over my WR driver), I quickly understood the new configuration is MUCH more expressive a...

[quote user="haralanov"]Actually I see the biggest benefit (besides the huge sound body) in the fact that such a configuration allows very precise adjustment of the way how the harmonics of each UB channels touch the midrange, by simply dealing with...

Charlus, it is not about an expression of gratitude, trust me, I am very indifferent neither to criticism or appreciation. Ironically what you are trying to do is in a way an organic holding a touch of a few audio ideas that I happened to advocate as...

Pretend
a driver diaphragm, any driver. From front diaphragm "sees" the horn
throat and the mass of air in the horn that diaphragm needs to
"push". This creates let call front spring. If a driver has a front
chamber than let discard it for now. ...
