It is interesting… complaining about the fact that the “promising to be claver” Cessaro Horn using the TAD drivers (still it is not completely known as they said that that MD driver cost €4000) I asked myself: what else they might use? Really, ...

If you know how in some optical systems imagery get destroyed when an aperture getting closed to F64 or even smaller, then you understand what happens in compression driver when frequency get higher and spaces smaller. Yes, the proximity of wavelengt...

I would like to make a few comments about the entire idea of those expensive Japanese compression drivers: GOTO, ALE and alike. I have voiced the near-similar outlook about the irrational exuberance that some audio people express about electromagnet ...

I would discard the first part of your post. It is it truly irrelevant what Germans, French, Japanese or Brits were buying and what particular brand and in what time they consider as “fashionable”. It is know that Ebay or Akibahara popularity has...

Well, when we are talking about Cogent we need clearly differentiate two things: the Cogent’s drivers and the Cogent’s installation. The problem is that since Cogent’s drivers are something so called “compression drivers” then their performance might...

Well, whatever you do with your loudspeakers of with you whole playback system is kind of irrelevant if your drivers are not right. In my view the drivers are the very much heart of playback but in case of High-Efficiency and particularly horn-loaded...

Well, I'm hoping the Azzolinas have something going for them. After all, it's not about theory but results. They came recommended as decent, so I invited them to be in my RMAF06 room. Yeah, I committed myself unheard, unseen. ...

OK, Romy, that EnABL stuff got my attention!I can't recall all of the bad ideas borne of good research, but this EnABL thing sounds a little fishy, and certainly it sounds too good to be true, as existing in a simple and really useful form. Can...

Gentlemen,
I suppose it is time to defend my sterling reputation here. The EnABL process does in deed work across the full frequency band. Works on all driver types and permits the very qualities that Romy seems to appreciate in the treated Linneum ...

hi romyi am listening now abought 2 weeks my orphean horns. when they arrived, i first connect them to my electronic crossover, and they sound horny, very bad. after i connect them to the own crossover, sound changed right away. now, that i heard mos...

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...

A six year ago or so when I played with different compression drivers I bought a pair of Dukane 5A540 and at that time I was not able to find any information about them. Nowadays I was pointed out that an eBay sealer “ bayleafs” actions a pair of Duk...

I have written in past about my lack of love to the BMS drivers. The crazy, as far as I concerned “annoyingly wiling” angeloitacare brought this subject to this forum while he was galloping across Web, “picking from graves” about his new dB-Design’s ...

Yes, it’s the drivers that inspired me to write up this thread. The response looks like it rises slightly atop but it is almost OK for this type of the drivers. Running the driver off the axis it is possible to roll off the HF rise. It is pretty much...
|
|
If you are correct there should me a large gap in the market for any company that really cares about sound. Returning to the topic of the thread, have you noticed wide discrepancies in the 'sound' of S2 drivers even between drivers manufactured withi...

[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...

We, the horn people, know what the compression drivers could do. The controlled dispersion, low distortions, low mechanical dependency, low magnetic anomalies, high efficiency, higher maximum dynamics and many-many more advance are well known. The te...

I seem to remember that we've covered somewhere the sonic benefits of SET at lower frequencies, but I guess I never really thought of ULF as "bass", per se. If someone ever comes up with an SET that can be an effective part of an AuraSound circuit, ...

[quote user="Paul S"]All I want is wide-range drivers as fast as a Lowther DX4 [/quote]Paul,
I have listened DX4 driver. In my view
this fastness that you report is completely artificial and absolutely non-musical
as it does not have any relation...

By the time I got seriously involved in hi-fi, in the early 60s, speakers and their drivers were already undergoing significant changes from which they would never "recover". Basically, for reasons that are no longer clear to me now, drivers and...

[quote user="Romy the Cat"]Here is the idea that I had for the “ultimate bass” for my room. Below is the picture of Macondo one channel as it is now from my listening position. So, if I find a way to deal with the wall edge at my ceiling then I migh...

Thanks for the link, el`Ol. The original Görlichs, when they still use aluminum layers were very interesting, thought they were soft suspended drivers that is not my cap of tea. BTW, for whatever it worth the Magico new version does not use ADT...

I just found this thread and can comment on the Enabled DX4s. Limono (Wojtek) very gratiously loaned his Enabled 8 ohm Lowther DX4 drivers to me this past summer (summer of 2008). It took my a while to make the crossover for these (I have...

It may be good, though i've worried about SS since Tymphany took over. I have seen many good companies with good products completely screwed by new management. Their re-packageing of Peerless into V-Line (or whatever the hell that was) sp...

Antonio,
The drivers are Seas Excel:

Hey, Guys, I have a question to ask. Are any in existence 10" paper-cone drivers with free air resonant frequency around 20Hz and sensitivity over 95dB-96dB? The caT ...

Hello again,I've found four Scan-Speak 25w/8565-01 and possibly two -00 for sale at a good price.I'm triamping as of today and hope it's a good idea to start with the four and perhaps add more when I can afford it.- Do you think the 01 version would ...

Hi Cat,The more and more I listen to reproduced music, the more I realize dynamics and tonal respect are key to start any reasonable installation. This kind of crosses over into some driver discussions so bear with me...My Tannoy 10" ...

The Aura
1808 had free air resonance at 24Hz and required enormous sealed
enclosure of 14-16 cu feet. Wilson Audio used the Aura 1808 in their
unfortunately-ported XS subwoofers and soaked from their relatively
small enclosure an extra 19dB...
