[quote user="Marc HENRY"]hi all,thanks for your interest !yes the frame is curved, HF and MF are //yes there is a phase plug in the bass horn. This cover 80-300Hz.there is a separate infra-bass section, covering 20-80Hz.images of the bass phase p...

This has been a very informative discussion folks. I am not a horn person... not through any lack of interest, but I am married. So, direct radiators rule.
However, I do not like the sound of speakers and so developed a process for turning cone and...

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...

After spending a day with RAAL’s “Water Drop” tweeter, trying to make a mounting harness for it I have to tell you that it almost a nightmare to handle it. Around this tweeter I was forced to recognize all objects I my room on magnetic and non-magnet...

I got today the Fostex F120A with all latest and greatest modifications on it. I put is in a temp .7 cu feet box with pretty much open back to see what the Fostex will be all about. I drive it from a bad consumer SS, composite-chip Hitachi amp from 8...

Yesterday there was the worst I can remember in my long-lasting with electricity. I mean it was not just bad it was beyond any description. My preamp has 126 steps (near a db per click) and during an average electricity day I listening it at 50-60 sl...

The people who use a single driver speaker believe the while their driver move back and forth for it also radiates a problem-free MF and HF. Near the same people believe that if an amp has capacitors with precious metals foil then it not only do ...

Recently there was probably nothing as low in audio as the BS surrounded Kharma loudspeakers. Each single step Kharma takes is further and further in-depth Kharma into the realm of bogusness. It is not that I find that “Kharma the Manufacturer” or “K...

This weekend a friend of mine visited me to listen my playback and there was a very illustrative occurrence. We listening my audio and everything was like it should be in the program. He was visiting my last time in 2002-2003, before the Macondo was ...

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="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...

[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 ...

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...

[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...

Last nigh I spend a couple hours to listening this thing. Since the amp is done in design phase and the final parts are still in order I can not finish it and close up – it kind of frustrating… Still, it gives opportunities to listen it knowing that ...

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...

[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...

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="jessie.dazzle"] If I get you correctly, the graph should display a range of around 12dB from top to bottom, in .5dB steps... Yes? [/quote]Yes, it would do, you might go for high or lower resolution, and there are no rules in it. You shel...

In terms of the length of the horn, I'm allowing myself a total height of 7'6" (just below the average ceiling height of 8'). In regards to the mouth diameter, that's another matter. (It appears that I will have to build two [2] different...

[quote user="Rewind"]Hi, I am slowly building my own Macondo. I understand why the injection channel is there. It brings some kind of softness that the compression drivers lack. [/quote] OK, but it is not how I feel about the service of injection...

[quote user="noviygera"]
For me personally, midbass is the most important frequency range when it comes to sound reproduction. I believe you will be on the right track to focus on this range because so often it is overlooked and treated with super...

It is not about Dynamic Range per say but about dymick differences that I feel and that I care with good ULF he effect of rising of acoustic and tonal pressure is instant, very soft but absolutely instantaneous. Live music has feel like literally...
