[quote user="Markus"]Very interesting discussion. I have taken a close look at Marco's horns and am thinking about using them in a horn installation. I plan to use the TAD 4003 from, say, 1 to 8 kHz, and a tweeter above that.
I would love to use ho...

Plenty of theoretical problems at every turn, but is the R from thick wire really that important? Likewise, I am not sure of special/worse probems from iron core chokes, although I am aware of hysterisis as a theoretical problem.I am in no posi...

GOTO always recommend to use 1st order active crossover and 2nd order passive crossover. The reason to use 2nd order for passive crossover is to protect the driver. Of course, the user can use whatever they like the best but the recommendation ...

Paul, I'm only learning here but if I understand correctly, a passive Scanspeak will not effectively lower the Fs of the active Scanspeak/s, as the notch is at the Fs of the passive radiator, irrespective of what the active radiator/s is/are. ...

[quote user="Romy the Cat"] Hey, look what I found: 3’5” passive radiator with 30Hz own primary resonance! That is what doctor ordered!

Not to mention that this beauty costs $12!

[quote user="George"] Recently I had a brainstorm (very small) and bounced it off Guy (who is a terrific person to talk to) and he thought it would be worth trying. Since I was driving such a relatively long length of RCA cable (thus subject to noise...

[quote user="noviygera"] I want to listen to both 12db/octave and 6db/octave passive versions and see which one sounds better. And keep the one that sounds better. [/quote]Herman,
It depends what you would like to listen. If you would like to ...

Hi Romy,
I just want to add my experience I had last year with a transformer based (actually it was an autoformer based) "passive" preamp. I thought that this could be the final solution in my preamp quest. Alas, it was not the case.&nbs...

Thanks for your comments, Roman.You're someway right... Goto foolishness;-))) maybe... also Mingsu wrote he "never" saw such a (Keith's - or mine) way to use S-150 mid-low horn... everyone's - me too, also with some doubt - copycatting each othe...

I am not sure I follow the TV analogy...I think that the best course where any sort of voltage divider/attenuator is concerned is to do it without messing up the audible results, of course, but also to keep it as "neutral", "transparant" an...

I had in my basement Marchand X26 crossover that I use over 10 years back. Since my B-2 power amp with passive filter is being fixed I setup the stock fixed B-2 with external Marchand active crossover. I spent some time to modify the Marchand X26 bi...

Markus,
If it is your task to stay with a single amp then all bids about line-level crossover are off. I would like to stress that although there are zillion theoretical and applied reasons to prefer line-level but still it does not mean that regula...
|
|
Markus, I do not know if you are right. I think to pay $12 for the passive radiators and to try might be one way to confirm it. I will have them in a few days. My rational (perhaps mistaken) why I feel that it might work and you might be wrong is fol...

[quote user="Romy the Cat"] the passive linestages (resistors)tend to be more transparent then active stages but it is only in the case when a passive line stage (attenuator) sits right next to the grid of your input tube. As long as a passive linest...

I recently had a visit by a close friend, who is an accomplished modern jazz saxophonist but a recording/mixing engineer, running his own small studio. We listened to some bass-heavy material on my Dannoys, the bass was acoustic - piano and drums. Da...

Hi Roman et al!Allow me to introduce myself. I have followed with amusement Romy the Cat for many years. He is ascerbic and ultracritical, but he does know audio. We share many tastes, like the Koetsu Onyx Platinum foir instance, on...

Anthony, it is not the subject of this thread but I am replying you since you raised a question. Is there are a lot of conspiracies about Tannoy vintage crossovers. They did many different versions and all of them well known. If somebody need I can h...

[quote user="Romy"] I see a problem. Sine you have 8 meters interconnects I presume that it a relatively large room with speakers positioned relatively far. This way your common remote control will drive two Placette passive units located a few meter...

Edgar, I completely miss you in all of your findings and I also was thinking about 15-in toy with a pair of sunspeak passive radiators. Indeed, Tannoys reinforced by sanspeak passive radiators is a magical configuration. I wonder do you dri...

[quote user="steverino"]FWIW I got my own PP 1050 a week ago and am pleased with the sound. It is the first active device that sounds as good as or better than my jury rigged passive filtration. Thanks Romy. As for chaining devices, I tried plugging ...

Interesting, I never heard the company’s products nor about the company. I have read everything they said.

I do not know how to interpret their claim it might be anything from pure BS to something real...

[quote user="perrew"]Romy,
I might be confused with the passive and active, but from my understanding you prefer your active 834PT to the passive RC network and passive LCR networks. You also prefer the passive LCR to the passive RC. So 834PT&...

[quote user="dazzdax"] what is your experience with passive transformer based preamps? Is this the ultimate way to get a perfect variable gain? Or do you prefer to use an active preamp?[/quote]Chris,
I think the terms of ultimate might be...

[quote user="Kcct82"] I know you're not a big fan of digital delay, but I'm using behringer DCX 2496 to make things easier... this way I get to keep all horn mouths on the same plane which avoids some reflections (from other horn mouths). [/quote]

[quote user="guy sergeant"] It's polishing a turd though isn't it? I listened to the 834 quite a bit when it came out and thought it sounded poor, even for the price. imho, The circuit's just bad. If you do all that to it it isn't really an 834 anywa...

....obtaining the same extreme results by the different means, although I do not know yet if it is possible….T, I do not think that it is possible to get from 9.5" woofer and passive radiator a good sound in context of small monitor. A passive radiat...

Romy,one thing that interest me is you use an active RIAA and the Allnic is passive circuit if I understood things?...

Hi,
[quote user="dazzdax"]Hi Romy and other fellow audiophiles, what is your experience with passive transformer based preamps?[/quote]I have yet to find anything better. If using active try using a TVC as volume control, it takes the active preamp ...

FWIW I got my own PP 1050 a week ago and am pleased with the sound. It is the first active device that sounds as good as or better than my jury rigged passive filtration. Thanks Romy. As for chaining devices, I tried plugging in my VPI SDS into the P...
