Hm, it is complicated. In context of ported enclosure (or passive radiator) it is imposable to talk seriously about the box resonance as a speaker/driver has no own sound but rather a summation of zillion resonances, aftersounds and the rest dirt tha...

[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 ...

[quote user="Merlin"]Are your observations regarding the ZH270 relating to comparisons with other push pull designs or SET's?[/quote] Well, both push-pull and SET and also some transistor designs as well, as I used to be quite a fan of Nelson Pass an...

And I do not mean this as a criticism.I had for some time an "original" Music Reference RM9, which was made by another well-educated genius, Roger Modjeski. The RM9 was AB PP with adjustable bias and feedback/gain, with 6DJ8 drivers and a ...

In nature, the SOUND always propagates "outwardly expanding", so to the ear, this is a natural thing.
Any containment is like a muffler on a car, constraining, restricting, resonating, chocking, forbidding, etc....
These are good tools to ...

It wound up taking 9 weeks to get my re-built cartridge back from/through the Ortofon DK/USA consortium, and then I let the re-built cartridge just sit there in is box for another 2 weeks. When I finally went to re-mount it, I managed to snap a ver...

Tenors bring a remarkable top-to-bottom continuity, which I've often
called the Kharma effect (the speaker, not the moral law of cause and

I am happy to have this here. I hope our members will take advantage of this and fill it up with information. I certainly will note any surprising observations I have with EAR 834 if I modify it.
It seems more like a general catalog of elements,...

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 ...

This is a new tool, so some training is inevitable. Yes, I saw your first sample with the peaks and my first thought was that it was not the deck, as I could not imagine a mechanism which would produce such spikes so perfectly repetetive (ok, maybe a...

of resonating chambers and cost audio coloration in most of the cases that do MASK

Hi alex. Sure the 12 incher starts narrowing around 700. But the horn does too. And in that area you cross both at -6dB. which contributes to narrowing vertically. The magic is, to merge in a way that off axis its not getting too odd in a complex sum...

I have identified a direction for my next speaker system. Whether it is a good one or not is a different topic -- I think it's a good one because I've lived with my current horn system for 10 years and have since developed an understanding of it's st...

[quote user="Alex Yakovlev"]Romy, would you mind elaborating on specifics of your power supply? My Bidat is going to John in a couple of weeks and I am finalizing my thoughts. Thank you.[/quote]
I do not have any “specifics of my power supply” as I ...

hey jessie-I've wondered the same thing-- and the more i end up twiddling around with it, the more I think it really either comes down to good measurements, or good listening! And in fact.. probably both in conjunction!I have a small 2 wa...

Experimenting with Decca carts, I've temporaly disconected the SUT's and decided to check the RIAA calibrationand I think I have some (circuit?) problem.[quote user="Romy the Cat"]
In the end of everything I was able to get very nice response. The...

Sadly I have never spent the time to try and correlate the sonics of a tube with the trace characteristics. Ok, sometimes it is obvious. A flat line is a dead tube. Normally I measure and compare both sections of dual triodes. ...

Roman:
since I came to GSC, I became more and more careful (at least trying) in proper choosing words, due to the need of expressing myself in a language which isn't my own, some finesse and subtleties get lost, so further explanation or underl...

Well, I decided it was time to start using some "proper" interconnects between the preamp and DSET's, ordered them and had them delivered. To date I had been using cheap interconnects from the local electronic shop (literally $6) which should be ok...

Yes, Paul, you are right that it has to be pointed that the frequency extension, by itself, does not guarantee anything (but that’s why I posted the thread in Audio For Dummies section :-) ). OK, now let’s see how the tweeters should be used (in cont...

Ant,For every individual the cause of this experience of dialog is possibly very different.For myself it is not so much the performance, for reasons it will be easy to see, but the composer and more closely the period when the composer live...

hey romy and all-i recently came across a strange phenomenon (to me.. maybe not to everyone else!).I just started using RTA as a method of evaluating my results with my own 2 way speaker system, and I'm finding that I'm ending up liking the sound of ...

Hi Roman!So, an SG-37FRP finally dropped on yr. laps;-) - glad it happened: not because you're now part of an Olympus-like lobby, but because you'll be able to judge with yr. own ears, much, MUCH better than theorically speculating on this or that......

Romy,Your Macondo system is something that has been a "role model" for what I'd like my playback system to be in the coming years. And much of what I've learned about horn playback systems I've learned from reading your writing and other posts on thi...
