[quote user="el`Ol"] I know the PAC tweeter of the WLM has the best transients and transparency of all tweeters I know and so is the best tweeter above 5kHz I know, although I hated the implementation (crossed far too low, harsh-sounding upper midran...

Okay... I also downloaded the original Milq SET amplifier PDF and have looked at it in detail as well as the 6-channel adaptation (DSET) and I understand where you're going with it... or so I think. In my particular situation, I've owned two pair of ...

This Sakuma’s is kind of BS. What I mean is that it has the appeal to be “good thinking” but only in the realm of marketing hype, something that the editor of “Direct Heating” had created around Sakuma. The reality is that the Sakuma’s TWO channel Am...

[quote user="coops"]I have re-read your post and your tone sugests that field coil drivers wi be used by manufacturers purely for their marketing appeal and not for any sonic improvement, Thomas Woschnick has just taken delivery of a pair of Ce...

Here is my proposal for an ideal horn system. The concept derives from the really of the horns as I know them, the available park of the drivers, the drivers’ real capacity and from… everything else that I might comment upon if you would not figure o...

[quote user="haralanov"] This experiment was made a few days ago by a friend of mine who is speaker repair person. The modified compression driver is Soviet made 1A-16. If you have the chance to compare the single layer VC vs. the original VC and to ...

Pete,
I do not think that it makes a sense to searched for “LF for use with Vitavox S2”. Do you think that there are good LF to use with Vitavox S2 and there are good LF to use with other drivers? I do not think so. The good LFs are good by themselv...

I did find replacement tubes OK (online), just not locally, like I had hoped. I have now recieved, installed and tested all new tubes but the 6N6Ps, which have been delayed in St. Petersberg by Christmas mail jamb-up. ...

[quote user="jessie.dazzle"] Assuming one will not get anything under 50Hz (usable) from a 40Hz horn, I interpret the mission of lower-bass channels in the context of a horn system as follows….[/quote]
Hm, this is a bit tricky with bass. A pla...

Ok, I have figured out why I have so extended bandwidth over 73kHz for my tweeter. I forgot that when I measured it I had the LPAD wide opened and in this configuration the parallel resistor is 20K and series is shorted. So, in that case I had just o...

Fllowing my experiments with Injection Channel

I have discovered recently that I was a greedy fool who should know better.
The new Injection Channel does OK as a independent single channel bu...

[quote user="oxric"]Romy's comments, not coming from someone who has insider knowledge as to the manufacturing of these drivers, must be taken with a healthy pinch of salt. Why he seems so opposed to these drivers which are not even that expensiv...

A few days back I posted the following post:

[quote user="KOTriode"] The Melquiades give me inspiration to build this 6C33C amplifier. It's on a stereo chassis that has few unique features - Vacuum tube rectifier separately for Input/Driver and Output tubes. - Regulator using the same tube ...
|
|
[quote user="KOTriode"]Romy, in the contrary, it is very unfair to compare my 845 amp with the 6C33C. The main reason is the 845 amp used the best output/interstage transformer available, while the 6C33C's output xformer is pretty good but far from b...

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="Romy the Cat"]I will slowly upload, as time permits to write them, different posts on the subject of Ultimate MF Compression Driver. [/quote]This will be a bit controversial subject among the compression drivers users but it is only ...

I do not know how about the “greatly produced music by the Bee Gees, M. Jackson and Uriah Hee” and the rest of the crap. It appears to me that you do not need to spend time “enough reading here for a few lifetimes”. You do not need audio sites bu...

I have to admit that I personally care less about powerful full-range SET amplifiers. I do not take their sound seriously, in fact I do not believe they are cable to do “right full-range sound” and what I see then I always imagine them with huge, bar...

[quote user="Romy the Cat"] The idea was very simple: to convert the C filter into RC filter, to employ the Silicon Carbide Schottky rectification diodes that showed themselves so nice in 6-ch Melquiades and to beef up the preamp with large bet...

Hi,[quote user="Romy the Cat"] I mean that EQ is a fine “tactical solution” but it a very bad strategic direction. [/quote]
I guess the question of the strategic value is dependent on the strategy.[quote user="Romy the Cat"] Look, there ar...

Wow, Jessie, thanks for the detail deals of your idea. I have spent last evening to contemplate many possible design configurations and I desired to discard all my former ides of metal fine-tuning, even my machinist in on standby expecting my ord...

I realized that this thread is slowly becoming the most sophisticated web recourse about Midbass Horn available. Trying to keep the thread educational I would like to introduce to my readers one more objective of my project. The subject is super ...

I tried the driver and generally I do like it’s sound a lot. It more sophisticated then Linaeum, it is more noble tonally and alike the Linaeum is seamlessly melts with Vitavox S2. In fact I am developing recently a theorem according to which a compr...

[quote user="jessie.dazzle"] For now, the amplifiers I use are a pair of Lamm M1.1s (was going to look for a pair of used ML2s, but more and more considering building a pair of Meliquaides). Using the M1.1s with a pair of V.A. Parsifal/Encore (direct...

[quote user="Romy the Cat"]Anthony,
First, your measurements again the “appropriate load resistor” has very little practical meaning. The
drivers is a dynamic system that has impedance not resistance and the impedance
varies with frequency. So...
