Wojtek, I am indeed hemmed in by the fricking electricity these days, to the extent that it is about impossible to hold on to a baseline for reference. And the Lowthers only make the problem more apparent.Yes, I still wonder about how I wo...

Bud,
I read the White Papers, thanks you for sending them over. What you are saying is very much correct, very much influential and very much disregarded by audio industry. Although I do not know if the proposed by you remedy might resolve/mi...
|

actually I agree with Romy, to a degree.... If the amplifier is a push pull device, using my output and input splitter devices of course, then an interstage transformer is a much better choice than rc coupling. Using transformers designed to the crit...

Jim,UL has applied a compatability test to insulation materials since 1976. This test places representative amounts of each material, found within a potential transformer coil, in a test tube. This tube is then evacuated and subjected to infrared hea...

This has been a very informative discussion folks. I am not a horn person... not through any lack of interest, but I am married. So, direct radiators rule.
However, I do not like the sound of speakers and so developed a process for turning cone and...

Interesting concept but let me point out a few considerations.The diffusor does performs a mild "equalization" function if you want to call it that but it is also an aid to dispersion. It is light "EQ"...3dB might be about right. Without any diffusor...

In that vein..... the only CD's that I have found to be worthy of
using, to copy audio to, are made, or resold, by TDK as the Music CD-R

Since FM long has been my primary at the most enjoyable audio source I decided to push the envelope a little further. The Rohde & Schwarz tuner bind via wide-bandwidth output with modified Yamaha T-85 MPX decoder sounds identical to Sansui TU-X1....

I've been thinking abut this question form several angles. Firstly practical.I thought I'd better see what low bass sounds like. And to get some idea of placement possibilities. So I set up my LS3/5as in the (rather cold) un-converted barn. Couldn't ...

Actually you are wrong. I am not a big or even useful played in this thread. About the subject of the Lowthers everything which could be said...

Bud, yes and no. They are right and the ultra high frequencies do pass any capacitors, indictors and transformers and I am attractive to the idea of filtering somehow by using the skin effect, I fins it is VERY elegant. The problem is that I do n...

HI Brian,
No doubt that sigint would incur a big increase in intelligibility, to say nothing of the improvement in music to fly and fight by. Works real good on headphones.
I spoke with a female development engineer with the Navy back in the early...

Romy,It is interesting that you say that the problem is well known. I discovered this application in 1972, while trying to come to a solution for the sonic insults being supplied by a pair of Ohm F speakers. I eventually got them to act somewhat as W...

[quote user="Paul S"]Yes, Bud, I agree that the most common problem for the full-tilt regenerators is that they begin to exhibit various problems in direct proportion to current demands. And this seems to be true even when they are used "below capac...

Romy,
First thing I would try is a single dot of Elmer's White Glue applied in the exact center of the dome, on the outside. The dot would be the size of a round wooden toothpick, cut off at the beginning of the taper. Dipped in the glue, the end of...

Yes, Paul, I know this company. It is always slightly annoyed me that it is Chinese company as Chinese manufactures very rarely, if ever, do any audio products with extreme or demanding performing characteristics. They rather do inexpensive mass-mark...

The entire pattern shrinks and grows geometrically, based upon the physical length of the edge of diaphragm involved. Please understand, this is not just a theoretical idea, I do and have done this process on many different types and sizes of d...

Bud, perhaps it does makes sense to try the “dotizm” one again. I quite severely review my view on the way in wish I use tweeter. I still am trying to make T350 to work, let see what I end up with. Nowadays my T350 sitting in 3rd order crossover, it ...

[quote user="Paul S"] I have been surprised that you have not already pursued the Zarathustra for your multi-driver, sealed LF. From your early descriptions of both, this seemed like a natural pairing and the most likely way to go, to keep the ...

Allo R,I'm afraid I don't have access to them or pictures for a while. I will try and get some towards the end of next week. However, I did just find an old post of mine on one of the other forums ... I think this should give Bud a decent idea of wha...

Hm, I do not know men, but it des not work. Over the last few years I have tried the ordinal metal diaphragm 4 or 5 times and not with the Super Melquiades it is the most successful try but I still feel than it is not the sound that I would like to g...

[quote user="cv"]Hi Romy, I dunno if you mean the C-core materials itself or the completed transformers... if the former (perhaps a poor term in this context), then http://www.elnamagnetics.com have what you are looking for. Seach for AMCC - these ar...

Please, have some fun. First download the white paper to see what the patent artists came up with. It is essentially correct but not to scale.
Note that it requires 18 offset sets of blocks around the periphery of a cone. About two degrees of space ...

Gentlemen,
I suppose it is time to defend my sterling reputation here. The EnABL process does in deed work across the full frequency band. Works on all driver types and permits the very qualities that Romy seems to appreciate in the treated Linneum ...

[quote user="dazzdax"] what is your experience with passive transformer based preamps? Is this the ultimate way to get a perfect variable gain? Or do you prefer to use an active preamp?[/quote]Chris,

I too am uninterested in Audio theories. I do not want to hear audio either. I design and build transformers, interconnect cables, speaker cables, treat speaker emitters, mounting face plates, boxes, etc., so I do not have to hear audio. List...

[quote user="rdrysdale"] I mean that with a horn loaded compression driver, a strong motor, and a very light diaphragm, the attack and transients are more life like. Because the diaphragm can more precisely follow the recorded signal, the reproductio...
