As late as the 1960s every self-respecting hi-fi nut had a "secret recipe" for "speaker dope". My own guru would not give me his exact recipe for speaker dope but insisted that developing the stuff was a rite of passage I had to go th...

So-called omnidirectional sound (of course here we are talking only about 360 degrees within a two-dimesional plane) is framed in the concept of emulating the microphone. This makes no sense to me, since it, firstly , fails to emulate the microphone....

I am sorry there is a mistake in my previous post, anyone who has played around with a dedicated channel for a 40 to 200 hz frequency know hat the only sound coming out is a wooo, woo, woo... Not much to do listening test by, we can measure, but te...

Am I the only one here that's super exited about these new horns? So how do they sound -- you promised to tell us ^^Be objective and truthful now :)...

[quote user="Romy the Cat"]In fact you can model the great sound for very, very small rooms (headphones) with existing direct radiators, have great result and no need for horns.[/quote]Yes, this is exactly what I've attempted to do. The rooms in the ...

...and we will start some little Polish mafia here, explaining to the morons the benefits of soaking not only our brains but also the diaphragms of our speakers with premium Zubrowka,Chopin or Zoladkowa Gorzka vodkas ;-)Seriously, nice initiative, ho...

[quote user="Wojtek"]I'd like to point out that Fostex 500 MKII is very much not sharp and artificial sounding. If anything it's an opposite -little too syrupy , soft and round so it blends with cone mid better than beryllium tweeter.[/quote]

Interesting, Keith. You got 95db at 23Hz, I thigh the idea of to use tapped horn it to get more sensitivity. Did you intentionally did not target 102-103dB or you went for wider bandwidth instead of gain? You also use 300w SS amps. Did you try to use...

the blue horns arrived today....and they're all hooked up and sounding..............FANTASTIC.......!!!!!!
In 10 years of DIY audio, there's a few moments of sheer joy....tonight was one.
Will muck around with placement of h...

A few days ago I visited a local friend of mine. He has a decent audio setup in his living room with mid-size monitors. Leaving aside what sound he is getting just would note that I know what to expect in his room. This time it was a bit more the...

What's being missed here is this: The parameters of location are fixed by the recording engineer/producer.Your typical Telarc has such a distant sound, one's only choice is the "you are there" reproduction.Your typical traditional piano recording is ...

Actually I am not preoccupied with the discovery of how the anomaly might sound. My primary interest is to discover if this “mystesises” is avoidable sign of the tube ageing. If so then it would be very good. I will send you more used tubes…..

[quote user="zanon"]Does anyone know of CD mixed especially for headphone?Maybe two mics, 6 inches apart, is the correct way to record for such a playback system.[/quote]The problem is that even with artificial head recordings you don't get a proper ...

If I play my trumpet into a tuba bell and the tuba player just moves his fingers without playing, the trumpet tone is modified and sound like a mandoline. In addition, the upper register becomes almost unplayable due to the modulation affecting the t...

[quote user="guy sergeant"]It does seem that with DHT's how the filament supply is arranged has a huge effect on the resulting sound. [/quote]
Could you elaborate on that “huge effect on the resulting sound”? What does it means and how did you...

[quote user="Romy the Cat"]I can tell you that it is very much unknown if it work. Well, we need to defend what is “it” and what would be the definition of “work”. In my response you missed a very critical element - the notion of “starving grounds” a...

I do not know anything about it and never heard about this conditioner. Today I was pointed out by a site visitor to this power conditioner and the visitor claims that he likes it, witch itself means absolutely nothing.

Fulcrum , sure it helps to get better sound but the curves you have just made is not sufficient to any serious improvement.if you are serious about room treatment and acoustics basically you should know what happens in corners ... it can get complic...

Clark, I have wondered if you ever "hear" the old records you are surrounded with, because the atmosphere is so "historically charged" that it simply imbues the space? Even in rote terms, those 78s have to make for good "surround".Hard to imagine fr...

I would like to pass some observations on my about sound quality in my video room. The sound in my video room is what I would call very very good, I am not kidding – really good. It is delivered by Altec 21S speaker driven by Yamaha B2 amp and ...

OK, given my usual inattention, it took me a couple of readings to understand that you refer to the inherent differences between the rote sound from sound reinforcement tools and that from home hi-fi. Of course I have gone on ad nauseum about these ...

It seems like most of the effort these days goes into trying to make these things able to play and convert anything to everything, and scant consideration is given to the resultant sound. Does anyone else remember the little Sony "Pro" Walkman tape r...

The peruse the similarity of “live” sound and the sound reproduced by a playback system is one of the most foolish notion that the audio marketing people implanted into the feeble brains of audiophiles. Never, under no circumstances compare “live” so...

[quote user="Paul S"]I never heard SS that could match a 45, but I have heard SS that has "less SS sound". Given your stated objectives going in, I "recommend" finding a more polite SS amp for the tweeters. Not much EMF, and I suppose not much power ...

Bill, it sounds like you have made a significant investment (time and resources) into (re)producing reverberation with your entire system, also setting time alignments of various drivers, across the board, and I assume you would not have gotten this ...
|

Bill, of course I supposed the DSP-free sound would sound better than processed to me, based on my experience. I just wanted to know how you felt about it, when it was put like that. I went to big SS amps despite I prefer the sound of small SET amps,...

Paul,
Thanks for pitching the Johnson capacitors. They do not look “large enough” for me. I used in past the following caps:

They have very good size to value ratio. The ironic part that I just called to th...

I'm sure there are many bad implementations of the 845 and 211. Almost all of the commercially available ones are pretty mediocre. However I have heard good examples of both so I know it can be done. I've yet to hear an impressive 6C33 amp so it...

It sounds like a lot of the circling has to do with which 2A3 "sounds better", outright. In any case, I'm guessing everyone would agree that it is specious to argue about which 2A3 sounds most like some internally-estab...
