John, I disagree.
No one deny the importance of harmonics and you are right saying that “If a speaker does not reproduce the harmonics correctly, then the tone is not reproduced correctly.” However you are talking about a complete speaker, not...

Paul:To build on your thoughts -- I have a sound bar for my TV which manipulates phase so you can pick between the audio seeming to come from a wider source, or from a focused point source. So, for your action movie set it on wide, and for your perio...

Impossible. A passive radiator can NOT change its tuning frequency on the fly. It is a Helmholz resonator - one single tuning frequency. It is also NEVER in phase, it is always late as it takes several cycles to ...

[quote user="AJ"]Hello,This is my first post to this site, which I have been absorbing for over a year.A horn project that I have been considering would include either a 1 inch or 1.5 inch throat compression driver into a Tractrix profile horn of...

I did mention to Steve about the angling of the horns and he told me that he started with them horizontal, but preferred them angled as in the photos. Who am I to argue! :-)The crossover phase change was because he's using second order crossovers whi...

I have been doing some work with integration of tapped horns. I have discovered some interesting things that are not being discussed on any other forums. I’ll start at the beginning so a full picture will be clear. At first I placed the tapped ho...

Djjjj,instead of reading the Macondo axioms, you ignore me and ask if I have listened to the ESD system. What difference does it make if you do not know what I am talking about? Yes, there are serious flaws in the ESD system. If this is the best that...

Those look very nice. Do you have a photo of the phase plug?...

[quote user="ulf"]A few years ago we discovered the tractrix horn for MF use. It was really the most important improvement so far. No more honking exponential horn sound. The improvement was so clear that A/B testing was not needed. [/quote]
For wha...

[quote user="drdna"]Looking again at the EdgarHorns, the placement in the room seems nearly optimal and they are now properly time aligned. Looking at the phase of the individual drivers and listening to each of them individually revealed that ...

Hi Roberts, Romy and others,Before this thread vanishes in undeserved obscurity, I have a question or two for you. I understand that the issue is a complex one and should be addressed with more care and paying attention to detail than I am do...

OK, after a few days to straggling with this damn tweeter I might report that the Water Drop actually made itself to sound civilized. It sounded somehow fine alone but it was a real nightmare with Macondo, I juts was not able to integrate it. I measu...

I would like to suggest an alternative factor or explanation to your recent ULF/midbass findings.When you were chronicling the design and implementation of your midbass horns I was curious as to the effect of the very close placement of the two h...

First major audio observation that I made is that my Super Melquiades should be revised. After a year and a half of using the amp I came across to some conclusions that outlined the prospective changes in my DSET.
1) The phase inverters after...

[quote user="Romy the Cat"]Hm you are true in the “terra incognita” territory as far as I concern. The preamps are mystery to me. All my attempts to make any decently sounding preamp or even buffer failed. To me Placette was truly God sent and if I g...

Looks like the phase response is quite complicated, with two phase flips between the knee and the Fs notch, but the PR phase eventually comes back to be in phase below the Fs:
"I
am sure we have all heard that a passive radiato...

Great analyses, David, thanks. I can’t concur as now with anything. Macondo in the room with midbass horn was a complex installation and with ULF it became even more complex. Some of the things I setup by ear and do not use measurements, I just know ...

[quote user="Romy the Cat"] Considering the problem you described, it was pretty much, where I expected it to be. However your explanations are kind of sound strange to me. If your tweeter were out of phase with the rest of the drivers then it would ...

I have always thought my old Altec 802's with the concentric ring phase
plug sounded better than my newer 802 G with the Radial phase plug. If i
had to describe the difference i am hearing i would say the concentric
ring style just simply sound...

[quote user="Lx_"]The effects on sound can be described either globally or in details. Globally the music flows less, the sense of musical phrasing is diminished, sound tends to tighten, feel constricted, dynamics are also reduced. When trying to...

Antonio,Works just fine with ported, unported or open baffle. The process works on the boundary layer of the cone. This is the very thin area between cone material and air. The actual mechanism just disallows energy trapped in this zone from reflecti...

[quote user="Hugh"]The best advice I can give to those willing to seek out the location is to put away your calculators and measuring tapes. Also, I'm convinced this ideal location tends to float around a little over time requiring slight speak...
