I already have some PY500 (it's a sign =))) ) and I have 836 too.I read about Malquiade amplifier threads.So it seem peoples on this forum like horn speakers (I love them too) and are looking for fast transient response, it's exactly what I like.But ...

Paul,My current active crossover is a DSP unit which likely has low enough input impedance and single ended inputs. I added BAL inputs by using input transformers. By no means do I want to use this combination as a representation of my crossover! I i...

[quote user="Edgar="]Not Amplitude. It's the rock solid phase linearity. It feels like a brick wall all the way up and down. I haven't looked at any graphs and haven't measured anything but that is my guess. There is no question of the great tone of ...

[quote user="perrew"]Romy,one thing that interest me is you use an active RIAA and the Allnic is passive circuit if I understood things?[/quote]
Perrew,
Among the none-commercial, home-made correctors here is my evolution of phonostages.

Paul, l I have written about it somewhere: the passive speaker-level crossovers on bass channels are no good. Marko has 250Hz that with 3rd order would be around 10mH and 2mH. With air core then would be very large coils with huge amount of DCR – ver...

Hello, would it be possible for us to see the diagrams and schematics behind the Zarathustra II in the same spirit as the Melquiades was conceived, noting that the best of ideas are formed with the purest of sentiments?[quote]It is Dima’s and my stro...

Hi Romy,Always nice to correspond with you, thanks for your comments.I used the term 'sophisticated' literally: so - phis - ti - cat - ed Adjective: 1. ( of a machine, system, or technique ) Developed to a high degree of complexity.As do you, I prefe...

Hi,[quote user="morricab"]Hmmm....I guess I can't really see that unless you are enjoying a particular coloration you are getting from the TVC.[/quote] Nope. On this you are wrong. Based on direct bypass tests the TVC's I USE (that is the specif...

Hy Paul, I agree with your comment about the tone of the passive radiator if it runs to the mid range. This is the point of the SS8565. the combo of the crazy stiff cone and the special surround works phenomenally well to stay linear. It is even bett...

Thank you Rowuk for the explanations.
[quote user="rowuk"]The Tannoy driver moves at 32 Hz, the passive radiator can only move at its tuned frequency - 30 Hz.

I understand what you are trying to say,...

These are Romy's original boxes and scanspeak used as passive radiator. I have purchased 10 inch tannoy reds with their crossovers to replace Romy's which I have given back to him. My Trinnov is doing a 24 dB Linkowitz Reilly crossover at 80 Hz. To m...

I guess I have found a more or less usable new configuration for ULF channel. It is 28Hz, second order, with slightly raised ULF on the transition slope. It sounds quite good. Well, I am not supposed to say this. It doesn’t sound good but it sound pr...

Mr. GOTO is a very shy person and does not want to force his view to others. But when asked, he always gives his best answer from his experience. When his customers want to try something different from his recommendation, he will encourag...

I heard the Everests recently at the Munich Hi End show, unfortunately they were being used in an active vs passive display/dem , you could tell when the Everests were playing as the active speakers had a sound like an inflated balloon being rubbed w...

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 throat S150 horn.&nb...

Hi,[quote user="morricab"]You may be right. It would perhaps be worthwhile to look into "better" transformers but I am not sure that an advantage can be found over just going RCA to XLR adaptor into the balanced inputs and thereby bypassing the...

Seriously, those rear firing woofers (with bass reflex, driven by SET and only internal passive speaker covers) could be one point worth ridicule. The length of the cables, and size and probable acoustic deadness of the room, might be others. There...

Is it too soon to talk about amps and X/Os, line or speaker level, active or passive, etc? If nothing else, it might save years to use a "board" to establish profiles, especially since the speaker positions will be fixed, and there are (almost) alwa...

Im building a passive mixer, so will need a few.I'd appreciate a leg up. I'm not interested in splitting hairs on the 1% difference between the best pots out there. More looking for recommendations on what is good in the 80% realm. As in a decent pot...

[quote user="Reno"] ok. maybe we have a different understanding of "electronic equalization". We do not use active (i.e. electronic) equalization in the amplification chain. There is of course some equalization in the passive crossover but I real...

Peter, I wish I had more confidence in the amp's power supply as significant proof against the full range of AC power nasties. In fact, I have long had the sense that there is such a thing as "over-regulation" where hi-fi power suppli...

Th fabric adds resistance to the tuning, so the tuning of your bottle changes. And if that's the effect you're seeking, I fail to see how the passive radiator will achieve that. You could introduce some resistance in your port, but that would again c...

I heard the new or at least new to me Accapellas in the Marriott, ( the DeLuxe show which is a spin off) I thought they were pretty good, plasma tweeter,cone driver and mid horn and a passive bass which was sealed?I think they used to use active bass...

I never had a chance to play with various preamplifiers in a very high-resolution system, but all the attempts that I've made with my system at home are constantly returning the same result - passive linestages seems to be the most accurate one....

[quote user="drdna"] I know all the compromises involved with the EdgarHorns, I have heard them when I visited Bruce Edgar in Gardena, and they were pretty good compared to most of what is out there. I realized that I would likely never be able...

As to the best transformers souding more transparent than the best resistors, I'll believe it when I (don't?) hear it. You claim to have heard this but I most certainly haven't. Based on theoretical arguments the noninductive metal film r...

>>Gera, are you catapulted from another planet? Are you sure that you want to drive a mid horn with Rowland amp?
Romy, some people that know me will say "yes", I am not sure... Of course no, not the Rowland to drive my horns, this is the amp ...

If Lamm ML2 is not enough good for bass you can use crossover and add a wilson passive subwoofer.Lamm ML2 will do his job better if you use a high power amplifier for wilson subwoofers.this approach will also reduce the Port noise of wilson alexandri...

Yes, I was implying the dipole-centric results (open buffers, ports, passive radiators and so on). They all has tendency to “demean” the significance of Sound by introducing the false sense of comfort that reduces the original anxiety and complicity ...
