[quote user="haralanov"] My driver has not even a single trace of tizzing top end. Tizzines is intrinsic feature of ribbon drivers (including RAAL), not of well designed paper drivers. Actually, the heart of my acoustic system is ultra high perf...

Very cool results I’m get in here. I took the new Slagle’s transformer that has reconfigurable sections and put it in the Milq. With 13V on primary I have 625mV or 520mV on secondary, or 20:1 and 25:1 (with 200-300mV normally drive the speakers ...

Since I kind of targeted with my YoYo tube to the RE604-class then I am considering to pay once a lot of money and to buy one of those RE604 to see how much YO186 better or worse. (BTW, do not be under impression that YO186 is cheap – it is not still...

Wait...are you saying that FOUR people who have been to Camerata wrote you offline (within two days!) and they neglected to enter into this relevant discussion?Strange! H'mmm? If I were the guy mentioned above, I would have been in here screa...

Thanks, floobydust.
There are a lot of interesting points in you post to consider. What speaker you drive with your 2A3? If they are relatively high sensitively (like compression drivers) then did you consider going with a single stage? I think I ha...

[quote user="DHT4ME"] This is true. It comes down to thermal cycling. I love the #26 tube but it is real hard to get quiet. It has a 1.5v 1a filiament. The heavy draw causes thermal cycling which is very hard to null out. There is also more rati...

Hey Romy,
Goto makes 12" and 15" woofers at 100db. I recently found out they make a small two way system using an 8" woofer. The 8 incher's range is 55hz-8000hz so I'm thinking it might be a good candidate for use with 60Hz h...

Jessie,
A few hints. If you are moving from Parsifal/Encore and LammM1.1 world into the world of SETs and Horn then do not be in hurry to commit yourself and do not create to yourself artificial addictions.
When I talk about artificial addictions I...

jd, I cannot see any of PDF files, probably my current networks kills them.
I do not know the AK150 drivers. I know AK157, AK151 and K15/40. If they have significantly lower free-air resonance, at 30-35Hz then I am not sure that they would be ...

[quote user="slowmotion"]I'm not so critical as you to open baffles for midbass, tho, in fact I think they can be made to work quite well, if one doesn't have the room for midbasshorns. [/quote]
You suggest that open baffles might be more successful...

[quote user="be"] Instead of defining the ULF range from the reproduced instruments, it is much smarter to do it based on the first resonance frequency of the listening room, because the frequency response of a closed room has a 12dB/oct rise in ...

A site visitor sent me another video of Silbatone from the last show:
Another video of the room playing barbaric music. The only missing part from this video was Joe the Archeologist , naked but wearing a ballet skirt and j...

Joe,
The “decoration” you described came from the fact that you wrote your message on MS Word that adds ugly formatting when you paste it into native HTML editors. I also write in Word and I uselessly before I unload my posts I paste my Word’s text ...

John Hasquin showed up a couple days ago and suggested that many of modern compression driver manufacturers design thier products to get the "best" publishable parameters while completely disregarding any basic horn design rules and actual sound resu...

Stefano, welcome to the club, not the GoodSoundClub but the club of understanding of what is going on.
The subject of drivers in Tailored Audio™ is complicated and one of the biggest problems in this complicity is to defeat the attitude of judgment ...

Yes, Rulit does try to push envelop of something. He does exiting projects but I do not know how all of it manifests itself in actual results. I said that he pushes the “envelop of something” as I do not know what this “something” is. I never h...

I know – it idiotic even for my site but it us what it is. I do not think that I can generalize my observations as I have not a lot of experience with DHT tubes but one thing that I have been observing for the last week is really arouse my curios...

[quote user="Romy the Cat"] When I said four transformers I meant that I can see 4 type of the tubes. The 2A3 with 700-80R on plate, YO186 with 1200R on plate, the 45 with 1800R on plate and 10Y with 5K on plate. Hey are requires different transforme...

[quote user="cv"]AlloI had a theory that the bug screen was helping to damp horn modes/refelctions caused by a mismatch between the S2 internal flare and the horn flare rate. I have 340Hz flare JMLC horns, which may be expected to give less of a mism...

[quote user="jweiss"] When we spoke at CES, you mentioned that your experience with field coil drivers only extended to cone types. So I assume that you have never heard any field coil compression drivers. That would include the WE 555, 594, RCA 1428...

We had this exchange with Christopher Witmer, who lives in Japan, via the AA about the new driver form some small Japanese manufacturer. The dirt who runs that form has deleted the whole development. Hm, people wonder why for years I have a vocal and...

[quote user="vinylithicum"] Here are some of my observations regarding the Wolf von Langa RCA 1428 replica. I long time wondered where mr. von Langa gets his phase correction elements and the diaphragm for his RCA 1428 replica. It's obvious that ...

Joe, I do appreciate that that invitation is open-ended and I might take advantage of it sometimes. Frankly I do not feel any specific temptations that I need to “drop everything” and to run to another side of the globe to audition the Silbatone. The...

Yes, Jonathan,
I have seen this resemblance with JBL in the shape of the back plate but it does not mean anything. The curved back magnetic path make a lot of sense, so he might adopt it from JBL. There is nothing wrong with it.
I do not k...

It looks like the Cogent boys came up with a new design. It is good that they are keep looking, even thogh they unfortunately are restricted with their desire to stretch the use of their drivers over too wide bandwidth….
The new Cogent setup lo...

My first impressions a about the “differences” of field-coiled derived form the time when I ran the Telefunkens war time drivers but at that time I had no reference how the same driver would act with permanent magnet. Also, the Telefunkens are the re...

[quote user="cv"]A couple of things to correct
here - the horn flare is not conical even though the exterior surface gives
that impression. [/quote]
I think you are incorrect. Even if the horns do have some internal
belly then they still look m...
