Me! Me! Me! Me! Me! Me!
Me and sub-90dB sensitive speakers and not SET amplifiers! I would rather raise money for Bush/Chaney campaign or to merry a Fidelity Investment business annalist.! However, it is what I am currently listening.

I would like to extend my last previous post a little. First off all, I would like to remind that I am very much not an expert in usage of transistor and second - I would like do not convert this thread into those DIY desecration: as you all know I h...

The other night I listened to a Girl with Guitar master tape. A friend has a home recording studio that would make most comercial studios not only jelaous, but also broke. A highly modded ATR 102 in 1/4" half track and a vintage stereo microphone; ...

[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...

I was sitting in the pub a few years ago and overheard a conversation between two audio engineers. They had been drinking for a few hours and had reached the point of grand challenges & wagers."I can assemble a music reproduction&n...

BTW, I was not kidding about the dual-concentric 8” Fane. They did make a version of Studio 8M with a tweeter in the middle. I have it sitting in my driver storage…Another BTW: the tractrix curve was not introduced by Br...

Yes, Markus, thanks. It is a bit too obvious that Speedysteve7 is not a typical DIYAudio moron. As the evidence: pay attention the Speedysteve7 posted information about his playback and has no following. In contrary of him installation would be 2...

The reason that I built the 6C33C preamp was to explore the 6C33C true musical potential like I did with the 845. Not only did I compare the sound of these tubes in power amp, but also in preamp. The reason is that with power amp you might hit some l...

[quote user="Paul S"] If you have the Mercury SR2-9013 35mm master Dorati/LSO Nutcracker, that might be a treat [/quote]
Hate that performance. Dorati did not play Tchaikovsky appropriately. Each and single Dorati’s Tchaikovsky piece sound to ...

I'm probably revealing my ignorance by even asking this, but I'm
curious to know if a field coil ribbon tweeter could be practical. It
occurs to me that if one could be made, it would be a lot safer since
it wouldn't be a black hole for magnetic o...

Romy,
No, the DAC was not set at maximum level (for best sound) while Cyrille listening to the system. It was set at normal volume for the whole system. When Cyrille dropped by, I was showing him the Field Coil open baffle speaker system which con...

A German company Avatar Acoustics makes loudspeakers with adjustable positioning of their ribbon-tweeter. This is very much with the context of this thread although I’m questioning a lot of things in those loudspeakers (pretty much everything beside ...

[quote user="serenechaos"] If I were in your shoe I would take make as you wish but wish a slight correction:
65Hz Tractrix from ~80Hz to ~800Hz w/ fane 8" ( or better driver) 250Hz LeCleach from ~800Hz to ~10kHzJBL 2405 ribbon from 10kHz up

I kind if cycle my attention on the notion of compression and it is not accidental. When a few years ago I used the hugely dymick NT51 tweeter in my car I experienced problem to set the right volume and I run the volume control 10 times more fre...

...we'll have to compromise somewhere. So, since it isn't the spkr's range, then it must be the amplifier. Forget the ML's 18W. We must have ~38-40, so let's say our machine is using a 45 / 211 / 610 /g70 type of tube.Also I don't suggest we conclude...

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...

[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...

Can you remind me what you do at this forum? I mean, if it is what you like then the BS of a horn-snob like me that being constantly expressed at this site should relay drive you nuts… :-)
Anyhow to be a little bit more serious: my problems with Qua...

Congratulations on the construction and installation of your horns. May your pleasure at the results reward your effort and expense. I find their installed appearance even more geometrically striking than anticipated and I suspect now that some o...

I usually go with turns ratio. The ribbon tweeter has I
think x175, the 6C33C full range is 10x or 12x and 6C33C in DSET is whatever it
was – it is kind of irrelevant in DSET setting. The YO186/PX-4/RE604 I think
has x25 transformer. My loading nu...

Thanks, Greg
[quote user="Greg B"] Cap and L-pad resistor quality is critical even in the cheaper models. [/quote]
I do not use any L-pad resistors with tweeters. If you need to reduce the tweeter output I drop the caps and move the tweeter up at t...

The recent events in my playback made me to think about he new prospective duty of tweeters. Since the Super Melquiades was enlisted for duty the Vitavox S2 got it’s own dedicated amplifier channel and stopped to “see” the coil of upper bass driver. ...

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...

hmm...I didn't realise I had left my browser logged-in to your site (I left my PC on over night, downloading some files).'..the only advantage that class-D amplification has is cost, size, heat generation and power.'In my eyes, that's more than I cou...

Yes, Paul, I know this company. It is always slightly annoyed me that it is Chinese company as Chinese manufactures very rarely, if ever, do any audio products with extreme or demanding performing characteristics. They rather do inexpensive mass-mark...

I realize that some people have been raised from infancy with the Lowthers, take them to bed, etc., so I do not mean to do anything here other than air some recent thoughts on the subject and perhaps get a discussion going about these drivers and pos...

Chris, I did ask myself the same question: perhaps my given PTR9 is demagnetized. I called the last night to the owner of the tweeters and he said that he uses them for 7 years and they driver should be fine. He also expressed a lot of doubts if the ...
