[quote user="Romy the Cat"]Now my midrange channel need no upper range diffusion and now I feel that the result I’m getting from T350 is too soft and too transiently slow for S2. So, I kind of very mildly begin to look out there and to try top fugue ...

Wojtek,
I do not think that Martin has any time alignment strategy. You see, the necessity for time alignment is a basic fundamental principle, and particularly in horns that spin phase like helicopter. However, in many instances the horns are juts ...

Hi Romy,I see why you don't like the design. And in particular, the choice of where he chose to limit the frequency responses for the two channels. I see the benefit of the DSET approach in this context as you explained it. If I understand you, your ...

[quote user="Romy the Cat"] There were some educational for myself observations made, in some way saying something about this specific DHT, in some way saying something about Melquiades’ single stage version and the Melquiades’ full-range two-stages ...

Ok, Lx, that does makes more sense. Perhaps I misunderstood you as the impression I got from you was that you recognize some instant events through the PP in reaction to events outside of the PP. THAT is imposable in my view. You did well describe no...

[quote user="Romy the Cat"]PP has the ultimate tool that allows detecting a LOT about its operation. Do you observe the same behavior as you describe when you pull out the power cord and let the unit to run from internal battery?[/quote]I made experi...

Let's see "series crossovers"... hmmm, very interesting. Something to look into? Where can I get more information? Should I contact an audio tech to design one? Can I send the current crossovers somewhere for evaluation or do I also have send the...

So, my point is that I do not care if one or other company trade their regenerators and that I might get the same or near the same cheaper somewhere else. There is many Class AB power regenerators that are being use in...

Bill, when you were at my place I use two PP2000 running together as at that time I did not discover the effect. I was running my MF at -2dB and my tweeter at -1.5dB. As now I use one unit and I return back my MF and HF channels to the level as they ...

[quote user="horny"]Mentioning line and plane sources (and dipoles) at Romy`s site is sort of forbiden.[/quote]
thanks for telling me. i don't care about dipoles though. i understand that they have advantages but to me that's not good enough. t...

Dear Romy,
well the horns are actually not designed for HF. The intended working range is up to 5-700. But since we use low Q, only second order filters we want to have a rather large overlap in the crossover region and a fairly even pattern over ...

Hi Jorge, Marc, Adrian, Romy et al,First off, Jorge what's your asking price on the modified DEQX ? Which model is it ? Who did the mods and what are they ? I am very interested.Adrian, as I recall you live in San Francisco. You are sti...

This Sakuma’s is kind of BS. What I mean is that it has the appeal to be “good thinking” but only in the realm of marketing hype, something that the editor of “Direct Heating” had created around Sakuma. The reality is that the Sakuma’s TWO channel Am...

Spent quite a few hours last day to connect the transformers, rectifiers, chokes, filters, decided do not got for the bleeders but for more henries in the chokes. It works fine so far. Ironically and very much contrary to my expectations I do enjoy t...

I must have missed out on how you regulate gain to or from each or any of several "channels"/pass bands, Romy. I can remember years ago trying lots of EQ things to get "Flat Frequency Response" and finally giving up on all of it, including...

Maybe you should get spectral data what your power supply secondaries look like in an case, my suspicion is that we have the exact same issues as with high order crossover networks when our power supplies have "high order" filtration. Maybe we ne...

Haralanov, as far as I know, Madisound does not offer my ribbon. Mine is not a stock Fountek, but it is a re-worked version of the old, discontinued Fountek JP2, a very narrow "naked" ribbon (ie,. no coating), and 97+ dB efficient. I got my Audaphon ...

[quote user="Romy the Cat"]Joaco, thanks for sharing. You said that you use 2A3/45 amplifier, do you use choke or capacitance right after your rectifiers? It would be interesting if you plug a scope into your loaded regenerator and post a picture (ma...

Wojtek, I am indeed hemmed in by the fricking electricity these days, to the extent that it is about impossible to hold on to a baseline for reference. And the Lowthers only make the problem more apparent.Yes, I still wonder about how I wo...

Yes, it is what I was thinking: they had many microphones and before the blast they turn some of them on to highlight some sections or instrument but the microphones were too hot and when the blast went off it was ...

Another consideration where I am planning to make the single-stage Milq different will be the power supply for the thing. The amp will have my typical SS fast-soft rectification with mandatory “gentle enter” LCRC filter, however I consider it t...

You decided to go with mA or are they mV against 1R resistors?
I prefer the second approach personally and I feel that I can moderate the quality
of resistor and I can’t moderate the quality of the milliampere meter coil.
