Continuing to harass the readers of my site and myself with the good news about the performance of my SA8535 driver I would like to post a very educational article about the subject. As I told before, being familiar with sound of ribbons then never i...

At this point I think that the main advantage of efficient speakers is that they represent the best chance for a sort linearity that to my knowledge can't be gotten any other way. It seems like inefficient drivers simply do not sound the s...

[quote user="floobydust"] In any case, you bought an expensive pair of Fostex (F120A) drivers, never listened to them, had them modified with, what could be considered a controversial technique. You then put them in a simple box without a back, drove...

The Morons™ at AA’s between selling to each other what they did not like and topping each other on their shoulders came up with a subject what horn installation would be if price would be no object. The question is semi-foolish as price is never ...

John, I am bit puzzled with your response. I do not know what would be a proper material for cone/dome of diaphragm. The source where “tone” is born in compression drivers is absolute mystery to me and I in my holly naiveté believe that no one else k...

[quote user="haralanov"]…. acoustic filter does not rotate electrical phase of the signal. [/quote] I do not think it is correct. The rotation of electrical phase is not the subject of filtration method but subject of slop and Q. Of you write the sam...

[quote user="Romy the Cat"] A few years back I wrote somewhere that I “developed” a semi-mathematical formula according to which an acoustic system’s result might be absolutely objectively weighed up. I did not go very far with advisement of this eq...

I have just taken out of my system a First Watt F5 clone Tim Rawson amp, It was substituted by a Telefunken PP amp with 6AQ5 tubes. Let me to explain.
My system consists of 6 way horn loaded speakers. I have a round Tactrix...

I set up Remy with temporary plates and all the rest was absolutely identical to Dannoys. I do not have the sounds that I had from Dannoys. It is generally good but I really taken back by compression. Dannoys had no compressions that I felt and this ...

As with the "audiophile" recordings, it is often difficult for me to separate the sound, per se, from "the way it sounds to me", in terms of content. Also, IMO, even the best "sound" cannot rescue a poor score/performance/recording/mix/processing/co...

This weekend I decide to take my FM where it should be. I ran ~125” and installed a dipole on the roof of my building and serviced my tuner. The result was as expected but there was something unexpected. Along with all normal benefits of better anten...

As I process what you have said about "blending integrity" I hear a trumpet blowing right at my face, just like I did last night. But obviously this is my imagination at work. Do you mean in general the way tones exist and integrate ...

At first I plan to power the thing SET, with a known, existing amp (a triode wired EL84) which I've already built and know the Sound. It is not bad, but a little "warm" sounding (second harmonics, and is low powered for low frequenci...

I had many interesting listening experiences while I used the Water Drop’s Macondo. I would try to surmise briefly the sonic consequences of the Water Drooping. “Me” and “briefly”, would it be possible? Well, where did you see a Jewish boy who refuse...

Well Jessie, it looks like your wish has come true. The Vitavox site went live at 9 a.m. this morning. It has very interesting implications for the compression drivers landscape in that it suddenly makes buying a hi...

Mind boggling iteration! I.e. & eliminating common denominators, "If the sound is wrong... it is wrong."Agreed. IMO they are right -- ain't no two ways about it.[quote]The Cybernetic Audio System, on the other hand, uses a closed-loop feedba...

Herman, how I did it is not the subject for imitation or following. If you insist that you need to “start somewhere” then the best you can do is stop bothering your with all those BS concepts like mouths size, compression ratio, drivers brands, quart...

Haralanov, I am not sure what it has to do with ego and why I need to see the things “beyond”. If the things you are trying to address are irrelevant to you then do not insist that you opinion is relevant. Any deep MF horn act as low-pass filter, if...

Some thinking about Romy's Injection Channel (see the following thread) : GoodSoundClub - Romy the Cat's Audio Site - The "Macondo Ultimate" MK-XXVII, Revision 432 ... brings me to a question that I've had a for quite some time: When aligning a "norm...

[quote user="gordan"]Roman,I don't think I've ever read your explanation why not 2482? We are all on a holy grail path to find a (somehow) available good compression driver that can go down to almost 200hz in domestic conditions and there are not man...

sounds like just what Romy could have excelled in for a carrier ---- because beyond the maths you need to have EARS and DISCERMENT for what is being recorded and exactly how it's done. (I met some sound engineers that did NOT strike me very musically...

Perhaps there are ways to horn load Lowthers that do not screw up the sound, but I don't know of any, and there are other reasons, as well, for not asking LF from Lowthers.For me the best thing about the high-pass-limited Lowther DX4 in OB is th...

I know there are some people who would read the following and will consider that I am out of my mind but it is OK by me. I have no convincing explanations of the phenomena but I might testify that the phenomena does exist - my Injection C...

Dominik, in terms of technology advancement, it seems their new driver is better than their other models. But despite this, I’m not sure their transducer engineer knows how to make the drivers to be valuable in terms of sound/tone. I’m saying that n...

Don't worry Romy, I know exactly what you mean. I tend to discount the opinion of anyone who raves about a system's ability to play back patricia barber. Speaking of which, if I were in her shoes, bunions and corns aside, I'd be mildly...

Romy, You make all very good points. I probably shouldn't call the front of the driver a phasing plug, because actually the long wavelengths really don't care much about the shape of the exit, they will just pass right through...

then the idea of amp bypassing is relevant to the "clean signal" discussion. But regardless of the measured voltage out vs. driver sensitivity I suspect that there is too little of something in the way of drive and control between a&n...

The way I would handle this is make my own 4" exit compression driver. What I mean is select a woofer with known good sonic qualities that match your requirments. Then make a phasing plug for it. My past attemps have been decent. However, I have noti...

[quote user="Romy the Cat"]...but I was wondering how the length of the port and the most important the proximity of it to boundary affects sound. [/quote]A general rule is to keep the end of the port at least twice its diameter away from walls....

[quote user="MINGSU"] SG505TT + S150 horn crossover at 180 Hz is not recommended by GOTO. The SG505TT driver is not recommended to use with single throat S150 horn. Double SG505TT driver is recommended to use with single...
