Part 2 – Description and explanation
Anyone who have ears and a rudimental mind to understand what ears register, and anyone among them who played with MF channels driven by SET, know that subject of SET loading is imperative.
Let take for...

If you ask me the compression drivers is like the jbl 2420/2470 design only with an other back chamber. And the low freq driver really makes me think of an old alnico driver of jbl 2220A http://www.lansingheritage.org/images/jbl/specs/pro-comp/2420/p...

Sorry I misread, I thought you endorsed the use of PP tube amps with compression horn drivers. Well it looks like were still in the same situation of not making them work. I could go on about why I feel they don't work, but it won't chang...

[quote user="RonyWeissman"]The electricity comment is interesting as today I put on some jazz music and the HF is very snappy, excellent! I feel like posting on AA to ask people's opinons if it's the electricity or if my concrete horns are going thro...

[quote user="vuki"]The best sound at the Show (to my ears, again) was in Hiraga/Melody room. [/quote]Hello Vuki!To my ears this speaker has a very smooth-sounding compression driver that hasn´t deserved being combined with a 15" cone ...

They have a 17cm throats so in most cases it is better to get the version with 2" throat for compression drivers, shorten them for the right throat size and build a chamber yourself....
|
|
is the compression driver problem not solved by using multiple drivers all feeding into the same, relatively large throat, eg four 2.5 inch drivers into a 5 inch throat? The idea is that sensitivity to reactance will be much less at lower excursions,...

Robin, of course I meant to say above that the Heils are equivocal when pressed, and no reason for me to think a compression chamber mosh with another driver would improve this quality; but I am just guessing. It would certainly be interesting i...

I pulled a mono set of these exact looking horns out of a movie theater they were installed in 1946 :)the system consisted of 2 of these bass cabs and one gigantic dual compression driver horn on top for the entire theaterI am no horn guy and looking...

over here. By now there's no HD FM and digital radio uses other frequencies. My pity is that I only have ONE good classical station, but it still puzzles me how it can sound so good. Probably it has to do with compression. Once they broadcasted a con...

[quote user="Romy the Cat"]It is was not bad sound but the sound that clearly indicated that something is very wrong: supper compressed, complete absent of LF, huge HF extension. The whole horn sounds like a bad MD driver.[/quote]Open the back panels...

[quote user="Romy the Cat"]Even though I do understand that advantages to run dedicated operation system but it do not automatically implies that the result will be better.[/quote]No, not automatically. But I believe using a minimalist open source op...

Hi Chris, all Allthough most of the work is done by the compression driver at 5 K , I would still use a proper horn, a horn that loaded the driver down to 2500Hz would be minimum IMHO. You can still use a Le Cléac'h horn if you wish. ;) cheers ;)...

[quote user="cv"] Well, the Cogent (Steve Schell and Rich Drysdale) boys are building just such a beast: field coil magnet, (possible) permendur polepieces for >2T, Fs 70Hz, throat - dunno, but at least 3" dia, reduced compression ratio relative t...

It seems every conductor has his/her own interpretation/feel of Bruckner.Here is one from last sunday, Bruckner 5.http://radio.omroep.nl/u/201446/?silverlight=The concert begins about 19 mins. into the program, don't be too much annoyed by the mp3-co...

A $$$ solution for a bass array that comes into my mind are the sandwich cone drivers from Accuton.Monstrous neodymium magnet, underhung voice coil (for low flux modulation).Very low Fs.Relatively low QMS for use in sealed enclosure with transconduct...

Ralph (Cessaro) is in the process of manufacturing his own compression drivers, I have no details as yet, I believe the diaphragms will be beryllium not made by TAD.Also new and ready for release ,although not shown at Munich are double skinned carb...

Some wrong oppinions here :) As a fan I studiet it very precise. I mean very down to each inch.The path length is 1.68 Meters, Throat 250 square centimeter (7.5x33), mouth 2x25 / 50 x 97 cm = 5000sqcmThat makes a compression of almost 4:1Gives a cuto...

Imaging is what you experience from a good mono recording, which is closer to reality in a live performance, but kind of narrower. Soundstage is what you get from most hifi systems, a quite false illusion of music happening into its own fake, de...

Dear Romy,My speakers are semi active-I can turn of above 250 Hz- Do you think it's possible to just turn on bass, position them according to compression?Then fine tune by playing full range?Best regards, Armen...

I think it was Wagner who first incorporated in his composition the concept of masking. He felt that during loud sounds people are losing ability to recognize the instrumental complexity. Later on during the stupid mp3 times or digital compression, o...

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...

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...

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...

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...

For sure it is an interesting design. I do not know how they dealt Fostex compression and why they need to customize the tweeters that were made for them "by hands in Toking one by one". Would it be easier to induce the customization into the custom ...

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...

[quote user="be"]They mention an intricate back chamber for the high frequency unit, maybe thats the primary function of the tube, apart from positioning the unit relative to the rest.[/quote]
