The subject of electromagnetic, or as they called field-coil drivers, popped up at my site numerous times. (Look as it list of related threats). The advances or shortcomings of electromagnetic drivers are arguable, I have my vision, but it is not the...

Hello,This is my first post to this site, which I have been absorbing for over a year.A horn project that I have been considering would include either a 1 inch or 1.5 inch throat compression driver into a Tractrix profile horn of which I have not yet...

I have heard some nice speakers in Germany using the Mundorf Air Motion Transformers. No saliva, ample "substance" in their tone and a very nice integration.http://www.mundorf.com/AMTnews/MUNDORF_PRO_AMT_FLYER_2012.pdfhttp://www.enjoythemusic.com/sup...

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...

compression drivers are the way to go as far as i am concerned but obviously performance depends on the horn lens.my beef with ET-703 is that i don't understand its horn or whatever it is. if not an explanation i would like to see maybe some po...

Absoluitely! The bugscreen is an effective diffusor, if it has been installed correctly. The removal (of other compression drivers) bugscreens is indeed a touchy subject, which I only reccommend if it is fully reversable. And yes, I have used nylon p...

OK, the amp is running for the 6C41C for a few days and it looks like the tube should be burned-in sufficiently enough for now. Still I have to note that the sound of 6C41C was not changed since my initial listening of this tube.
Originally I drove ...

over ALE/GOTO/Others (apparently they actually know how their drivers work) if
that allow to someone design the horn exactly the way he/she want, and later

Very interesting… Earl Geddes just posted his thoughts for the Morons at the AA. I do not know is he was inspired by my post of by the completely foolish nose that the AA’s idiots razed around the Cogent’s Steve and Rich experiments but still – it wa...

A lot of people ask me about those drivers and I’ll try to compile my vision about them. I did try most of the possible tweeters: dome tweeters with cloth cones, varies type of hard metal domes, compression drivers with aluminum, titanium, phenolic a...

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. I am using a 12" JBL midbass driver (~100dB sensitivity) in a 50L single driver Marshall cabin...

Jan, I disagree. Obviously the ultimate intention is to listing music not the "imaging" or the “compression” but…. in order to listen music there is no needs for a good playback at all.
Audio and music are very different subjects of human experience...

Hello Romy,
I understand the difference between the kind of "basshorn" pictured here and the proper compression-horn that you use. It is true that many DIY-types like to make basshorns in their garage without much thought to technical consideratio...

It seems that I do agree with you about the sound of compression driver midbass.. at least from what I have heard in my own room.. I have heard the big ALE drivers you mention on a bent steel horn similar to what ALE builds, but of the owner's design...

You do not see any explanation is because you are not accustom
to think about explanations but wait that explanation will be brought to you.

[quote user="Romy the Cat"]I got the new BSO 88/24 files them briefly listened a few fragments. Generally I do like them and they are nothing like the 320kbps multi-channel WMA that BSO marketed before. My fear that the files might have issues with t...

Hm, this is what I am playing how: the new 18-cell and S3. I run it from a full time Milq and use it with no filter of any kid. Rony is right the depth effect is there, it is not even depth but rather multi-dimensionality. Indeed very pleasant feelin...
