[quote user="Ronnie"] I was under the impression that you did not at all electrically roll off the upper bass, and that the small throat would do all the (kinky) low passing. [/quote]
Nope I did roll of the upper bass channel as my driver goes all t...

[quote user="Thorsten"] First, the Lowther has ze wizzer cut off and has an Equalisation circuit to flatten ze upper midrange bump. Otherwise it is run fullrange, that is WITHOUT HIGHPASS OR LOWPASS. [/quote]
Probably this is why the Lowther sounded...

[quote user="decoud"] Romy, can you be persuaded to post a sketch of what you think the optimal 2 channel Melquiades circuit would look like? [/quote]
Decoud, I do not think that there is such a thing as optimal DSET. The entire concept of DSET is a...

A few days ago I spoke with a guy that I know form LA who told me about a story about his good friend who started many years ago an audio business in CA. He said that the guy initially hag a genuine interest in sound and music but since years pass by...

With regards to the links, as it happens, I totally agree that 15in Tannoy Reds struggle to handle complex music. The crossover is too simplistic and the cones too hard to control with a low power amp. Reds can be lovely in a simple vintage system bu...

[quote user="Chirag"] The more and more I listen to reproduced music, the more I realize dynamics and tonal respect are key to start any reasonable installation. [/quote]
Not kidding?! :-)

I would like to share more of my troughs about the ESD
acoustic. That are not truly the troughs about the company but rather the troughs
that come to mind inspired by the company come to existence.
I do feel that it is an ultimate we dream of et...

[quote user="jessie.dazzle"] Your latest post got me thinking in a sort of incomplete way about how you might locate the injection channel... If you consider tone as a harmonic of the original source, then (depending on the order of harmonic) it may ...

Yamaha B-2 reportedly was a top-flying amp in end of 70s, during it very brief production period. It has in a way cult reputation, so I’ve bitten it.
I was forced to very mildly and temporary modify it, just running the signal directly the ent...

[quote user="Romy the Cat"]I do not like the idea of batteries for anything. It is kind of ridicules to use batteries. Yes, in some cases there is some improvement on low voltage electronics but it is ONLY because the power lines are badly sounding t...

Mumford,
Let clear first with terminology. You post said about “Incorporating active crossovers into DSET” and I think it is not what you are interested; at least it is not what I am practicing. An active crossover implies a use a dedicated active s...

It is not secret that Stefano Bertoncello loves to appreciate
Goto and is very prolific Goto devotee. Some people love to be groupies of some
cars manufactures, or football teams or political parties. I never associated with any “group identity” a...

Thanks The CatI'm posting the pics of the build as I progress so people can see and pass on ideas, that's all. Are you suggesting you don't want horn projects shown on your site? I had earlier outlined the design, including cross-over points etc.I as...

[quote user="anthony"]My RAAL Lazy Ribbon has ended up needing a 1st order high pass filter to match the midrange S2 which is so much more convenient than third or fourth order as initially intended.[/quote]
In my case I found that RAAL ribbon wit...

Oh, yes this is the whole idea of Remedies, it is not only a Red combination but it is an assembly with midbass channel which would make it a conventional box loudspeaker. You see, with all interesting things about Tannoy Red the woofer part of t...

Ah, I think I have found the secrets that I was looking for. I still do not work with 15-in woofer but still try to make my red driver sound the way how I want and I got some revelation and the result that is very close where I would like to be. The...

[quote user="Romy the Cat"] I have to admit that although the Macondo “Water Drop Tweeter” sounds very good but I do not have that “shocking sound” that I got from the “Water Drop” during my initial introduction to it. I kind of always felt it and I ...

[quote user="jessie.dazzle"]As a way of forcing myself to see the thing as a whole, I will start by converting this schematic to a 3D CAD model, illustrating each component and its relation to the others (with more distance between the parts than in ...

Alex, contrary to the numerous speculation that many people more or less reasonably spread about the subject, my experience indicates that there are no such a things as “preferable crossover frequencies". The chosen optimum crossover frequencies are...

Guest napping now from 16 hrs jet lag, so I have a moment...Jorge, you raise an interesting point about THs. I may be incorrect in assuming THs sound worse as they play higher in freq. Perhaps instead the limitation is one of narrow bandwidth rathe...

Hi Romy, It's called "the itch". I was debating high and low before plunging for the Pass. I played around with the capacitance setting. I put it to ZERO and the sound lacked body. 100pf was a little better. Bass was tight but lacked absolute weight....

Christmas is a beautiful time for Jewish boy to play this audio project and I did last few days quite a lot of experiments. So far quite disappointing. Did a few implementations to cut off stress on the red woofer and compliment it with 15-in woo...

This is very interesting subject.
I expect that tghe new Midbass horns will have somewhere 108dB sensitively anechoicly. The driver is 99dB and the hyperbolic curve has much more EQ then Tractrix and that is more important the EQ that work mu...
