Romy,I merely thought that you felt I was riding roughshod over your advice, when it was in fact a degree of naivety requiring extensive clarification that may have made it appear thus. Regardless of your indifference to praise and/or criticism, I'd ...

Shannon, I am not 100% sure what you are asking. If you want
to drive SS with a single 5E6P stage then you have some difficulties. Dima had his version of SRPP with 5E6P to drive his SS and it "worked" very fine. http://forum.vegalab.ru/showthread...

I did not order the UnipheyeMusic. Tne only recording I was interested was the Beethoven quartet but I did not like how it was recorded. According to the UnipheyeMusic guy the artists were too “famous” to give him a lot of time for recording an...

I’m absolutely certain that the mids and lows are designed in the same function supporting fashion as I described the compression driver. Danley explicitly explains this in his patent. For my own amusement, I went through all the math and calculation...

[quote user="serenechaos"] "I think the ultimate length of the upperbass horn is 3”- 4” throat. With longer horn it would be very complicated to time-align it as the horn will mask out the MF driver."
Is this also why you use tractrix curve f...

The throat diameter of 7" is what I first approximated as an acceptable size, with the 4" being an alternative (should some unwanted effects arise, I may then experiment with the 4" throat). I can't simply assume 7" will be correct (though that...

Mark,
It is hard to say. I owned T90A sometimes in 2001-2002. At that time I was going through the drivers like crazy and T90A was just one of them. Looking from now I do not think that I gave to many drivers a chance as I did not “work” them trying...

Mani, BTW, if Silbatone-pimping Joe Roberts showed up in here then it had to be the Aporia speakers with the back-loaded single Manger were presented in the show. Why would Silbatone otherwise to drag to the show that big and expensive mastodon...

A Greek company Arcadian Audio come up with own new horn-loaded loudspeaker.

Anyhow, the Arcadian Au...

[quote user="Romy the Cat"]I do not disagree with

With Ming permission I post a fragment of his emails where he describes his midbass horn. It appears that he uses cone-drivers with ltooooooo ow Fz in non-compression application with no back chamber. Now it is obvious where he is losing his midbass ...

Looking at the pictures of CES I came across a new Seoul-based company Silbatone Acoustics that show off a new speaker “APORIA” in Vegas. It is a back-loaded Manger.
What I read the company philosophy I was not pleased.

It sounds like a lot of the circling has to do with which 2A3 "sounds better", outright. In any case, I'm guessing everyone would agree that it is specious to argue about which 2A3 sounds most like some internally-estab...

[quote user="Cosmos"] Anyway, as the description on our site on second paragraph says, the third 6C33 located at the back, is used as the pass element of the regulator (controlled by solid state circuitry) providing 220V with 100uV of random noise &a...

As I said before, in many if not all instances the provisions for “bad electricity” are deeply entrenched into the design of our playbacks. A few days back I took advantages of some new possibilities that PP2000 offered and made some changes in playb...

It is complicated. Any tweeter is different and the RAAL’s “Water Drop” tweeter is more different then others. Almond any other tweeters that I heard this tweeter has something absolutely unique- it has no annoying upper MF nose. When I asked Alex to...

I double checked and everything seems connected ok. all parts values are correct. I have measured the voltage across R2 and it was 208V so 208v / 15k = 13.86mA. I connected 1r resistor between M and R2 and it was 14mA. also connected 1r resistor betw...

Haralanov,
What you are experiencing in my view is an inconsistency and confusion between listening of playback presentation vs. content of musical message. I know that it is fashionable among audiophiles to claim “not listening to audio but l...

Romy,I understand your situation as a result of the move. It is a good thing because a system that is out of proportion with not work in a family environment and ultimately you will be battling yourself between sound and family priorities and practic...

actually I agree with Romy, to a degree.... If the amplifier is a push pull device, using my output and input splitter devices of course, then an interstage transformer is a much better choice than rc coupling. Using transformers designed to the crit...

Jessie, a few comments.
The back chamber mechanism is good. Are you planning to do the same in the midbass horn? Since you most likely will not drive your upperbass all the way down I think that the back chamber mechanism will be more effectiv...
