What Romy has done up until now is very similar to what a conductor of an orchestra does:Search for music to performBuild the ensemble to play itDecide on the venue to perform inTrain all of the forces involved to play in accordIn real time, guide th...

I am not sure what to make of the decision. I understand the quandry surrounding "high maintenance" dates but am not sure about the replacement. I guess we will see after the honeymoon. I am surprised that you have not tried - or written about the IB...

Reading Romys ventures for years has given me a (probably primitive) picture of how his "world" works. Regardless, the changes in his "style" of posting have shifted as much as the "content". I do not think that the Dunlavy/Dunnoys would have had the...

Not here and not on YouTube...

The subject of line filters and uninterruptable power supplies is one that has been pretty free of amateur DIY myths. No one seems to know what makes one sound good or bad and when. The subjects getting attention are IsolationReconstruction of sine w...

The idea of high quality delay makes me wonder if the delay effectively increases the virtual length of the room - allowing longer wavelengths before the room Schroeder frequency is reached. This would be a "softer" bass without the room compression....

|
Maybe it is just me but I cannot help thinking that videos simply take up more time and space for the same content. Let us take Romys video. 40 minutes. How many pages would have been a post with identical content? How long would it take me to read a...

The frequency where your room turns into a pressure chamber changes the way that we perceive bass. This is how we get "bass" in a too small space like an automobile. When removing the ULF channel, all of the music is transmitted in a natural way for ...

I too believe that "reproduction" has nothing to do with my audio experience as there is nothing to reproduce. There is so much missing in any recorded signal that the "original" geometry can not even be close to restored. At best, we could create a ...

A DSP is a great tool for modelling crossovers. It lets us experiment with a lot of things with no additional costs. There is a sonic hit, but far lower than "guessing" at crossovers.What seems to get the most traction here is using inherently well b...

|
Koh,if time alignment is critical (in my world it is), the sources of the sound (the driver diaphragms) need to be aligned. A very long exponential horn and a short tractrix are not „impossible“ to align, but what reflective surfaces ftom the exp. ho...

My thought is that you should ask John. He has the comparison, time and time over again.Horn response calculates pressure, but that has nothing to do with sound quality. Flooding a too small horn with too low frequencies is the sign of a beginner to ...

|
I suspect that the 8" and 5" cones and 1" compression driver are in the Danley Signature Synergy multiple entry horn. This creates a physically phase aligned point source above 45 Hz and probably a bunch of diffraction. The double 15" woofers are an ...

|
Hornresp only calculates pressure not tone. That means you can have perfectly flat response and not be able to integrate it with anything.In addition, no single channel can be viewed out of context. They will both change depending on what is below an...

This site seems to me to be the most lucid and FREE explanation of understanding winding OPTs. This particular link is to the PP OPT section:http://www.turneraudio.com.au/output-trans-pp-calc-1.htmlAnd here for SEhttp://www.turneraudio.com.au/se-outp...

We know that RIAA preemphasis is applied before the groove is cut. What is in the groove is NOT flat in response. Conventional playback regardless of MM/MC/MI needs to EQ that preemphasis out to get playback flat. The EQ has multiple corner frequenci...

I am far too impatient to keep a project of this magnitude going for this long.As far as tuning it, buy Romy a ticket......

Hi Jeff,I am certain that the best midbass was NEVER in a corner horn. Every fold in the horn is a new resonance. Corner horns need many folds...In addition, if you are very "anal retentive" about phase alignment - how do you integrate a corner horn?...
|
|
I think that there is a HUGE difference between listening to a recording for the first time, or a second, fifth or hundredth time. A live performance or recording for the first time is full of surprises - that disappear when repeating. The recording ...

Hi Alex,I am sorry, what you claim can not be. No cap is going to separate bass instruments better.The brilliance of the 834p circuit is that the EQ also uses the miller capacitance of the tubes in a very brilliant way. The power supply caps are very...

That being said, many of us seem to move away from pots and go to either discrete resistor switches or discrete resistor matrix schemes.As far as pots go, Alps seems to have the "good enough" market cornered.If you look through the site, you will rea...

Flm,You need to start reading what is already available here. This is not so much of a random blog like many others. We make efforts to stay on subject and have purpose. That means, a change to your system should have a reason that you can clearly de...
|
|
You say that you are looking for accurate mids and highs? Well, maybe a wide range driver could get the mids right, but if you have ever have seen a spectral analysis, you would see how much distortion/resonance is present - that many of us hear. Sur...

You really should read the entire thread on Romys Macondo before building anything. Horns are usually not very forgiving about using the bottom octave of response. Romy addresses this in his usual depth.I am using FAITAL HF146 drivers on 250Hz horns ...

You will find a very basic motto or life theme here that keeps recurring:Random efforts produce random results!In relation to audio, this means that buying somebody elses best of everything does not lead to a personal superior result.Basically proces...

Yes, the warts of bad music or badly recorded music will be more obvious and perhaps at the beginning very disruptive. I contend however that the human state is VERY adaptable and that we can develop techniques to accept the lesser attempts for what ...

One of my favorite sections here has been down for a while. Did it get Covid19, is the interface broken or have the sources incorporated link breaking software?...
