Part of development process.
They come out from "nothing" (even considering some eventual reverse engineering) with a set of 5 drivers supposedly to be sonically matching.

During the development process they certainly got all kind of sounds while prototyping and had to discover what each specific part of the driver does sound-wise to be able to match they all. If they documented the process (engineers usually do), they could tune characteristics on purpose to match some specific criteria.

Certainly there would have limitations, specially related with the limitations of the driver design, but with a fully documented development process they certainly can tune a lot of things with certain prediction of the resulting sound.

If they have the tooling it hard to believe the process would be really expensive with the unique logistics they have in China. Ever if they are using some very expensive custom alloy to build the drivers those are still metal and the discards can be fully and easily reused, that would not be free but far from expensive as buying all the thing again. In China this kind of arrangement can be made literally just knocking at the door of someone who is able to reuse the material.

Pay To Play
One thing for certain, they will want serious money before they get into it with someone.  And how many times "back and forth", tuning drivers to horns, each other, the amps, X/Os, and the room,  does that include?  I remember playing with other peoples' theater speakers, which had all been "tuned" by sound engineers, and feeling like it was hard to even know where to begin, even with "dedicated" amps!  Sure, someone might do it; but who has already done it?  Where are the examples?  There are good, practical reasons why Romy's system plans have millions of hits.  While there are certainly other ways to do it, it might take a while.


Best regards,
Paul S

ESD relationship with Mr. Sam Saye and Dr. Bruce Edgar
Hey Romy, this is Jacky from ESD and I happened to find this site. I'm really glad that you guys are interested in our products, but there seems to be some misunderstanding about Sam and Bruce, so I just registered to clarify a bit.
Yes, Dr. Bruce Edgar and Mr. Sam Saye are part of our company. ESD was actually first registered in California where I learned with the two masters and we built the prototype together.

Thank you.
Jacky, thank you for clarification. I have my view about Bruce and Sam being the “part of your company” and it will remind my view. I hope you will find the critiques expressed in this thread constrictive. It would be interesting to hear your commentary about what was expressed in this thread. Are you planning to sign up any dealers or reps at US’s East coast and make an East coast installation available?

Yes, Romy, there are lots of very constructive ideas and I learnt a lot. We welcome all kinds of comments especially the negative ones to improve ourselves.In October and November we’ll attend Rocky Mountain and New York show. Hopefully see you there and let you listen to it.And yes we are looking for opportunities in the US market, getting touch with some people interestedSmile

As Usual
Well, here's another high-end speaker that's aimed at...   well, who knows what they are thinking?  Surely their choice of music/program says something about their aesthetics, also how and why they made the choices they did in developing these speakers?

Some comments...
Well, as uselessly the host who did the interview is an idiot but it is nothing new. The music played is idiotic as well, there is nothing new in there as well, the high-end audio today is made to play this music. A few short words about the design decisions by ESD  
 
The hosts are wonderful. I would debate the selection of exponential horns for upper bass but it is valid decision. The horizontal offset of upper driver is monumentally stupid, particularly with exponential horns for upper bass. With exponential upper bass (which is small) the MF horn is probably at 34-36” of elevation and it live a LOT of room to put both upper driver in vertical configuration. Then the frame. If they position the drover in cardboard boxes then it will be fine but they make a finish frame and the frame is horribly design. The 60% of performance if this system is the design of the frame for the channels and ESD did very poor job with it. Changing the position of the drivers or angling horns for a fraction of degree will toss the whole system out of time alignment, presumably that it is aligned. The frame is the key in it and I have no idea why they did such a piss poor job. 
 
They the color of the horn. What was in their mind to make them red is beyond of my. Hey have spectacularly looking horn and they have absolutely barbaric looking delivers. If the drivers were black then it would be SO MUCH better. It is not about esthetics but about a normal modesty and listening culture. I absolutely hate the chrome bumpers on audio equipment and I hate the people who like them. The next step ESD would be to put the X-mas light on the horns and to make it to blink with each bass-guitar note… I am sure that this imprudent audio reporter would be ecstatic to see it…

What Ken Micallef told us from Stereophile?
When ESD Acoustic's Sales Manager Nicole He offered tea, and designer Jacky Dai played The Carpenter's "Close to You" over their six-horn, 23-component system, I for one felt a tear. Hal Blaine's drums and Karen Carpenter's voice were never so thunderous or awe-inducing.

What did Herb Reichert tell us?
Today, here in NYC, ESD had the biggest, most r e l a x e d, most natural, uncolored sound I heard—in any room. By comparison, in other rooms, there were ported loudspeakers that sounded more colored and obtrusive. Bravo ESD!

What did Sasha Matson tell us more?
When I got my breath back from taking all this in and actually listened, I heard unidentified acoustic guitar and Harmon-muted trumpet sounding "yuge," but in no way harsh or strident. I asked for something classical, and heard an older unidentified mono recording of Beethoven's Symphony 5. The Dragon horn loudspeaker system seemed to revel in the darker lower mid-bands of this recording, and simply exuded the thick and viscerally powerful string textures. However, on other material that included highs and lows from hi-tech synthesizer instrumentation, I don't know how you could hear any more sound—I could hear it around the corner and down the hall. This is take-no-prisoners stuff on all levels, and the kind of thing most of us can get to experience  only  at an audio show. Awesome ESD!

What kind of an IDIOT?
I would like to know how an IDIOT have had such a huge of money to invest & develop ESD himself more than 20M us$ now?
I couldn't  understand  why you like black then I would like it too?   I would like to tell you we can supply any color of driver if the customer like.
Yes, I am from China, ESD is from China, I am proud I am a Chinese.  China have Spring Festival every year, but no X-mas light. So never mind it.Hahaha Shall we audio is just audio, no political?
I do like a man speak politely and well-bred.
If ESD must be SUCH AN IDIOT just like you told us, I will be glad to be.  And I do hope there are more such idiot in the world, then no poverty, no rude, no  arrogance, no prejudice. Would you?
Thank you very much!

Go count the sheeps
God, where all this crap comes from? Djjjj, I do not know what is wrong with you. Take you medications, calm down and be happy with millions you spend and sound you got out of it, or at least with reviewers’ feedback, who chose to appoint ESD as the “flavor of the month”. No one attacks you on political or national base. If you have you own insecurities then consult you psychologist but please do not flood my site with stupid patronage.

Ok, ok, ok....
Hm, ok. I am cruel, out of control, idiot and barbarian, whatever….  I am very comfortable with these accusations. Please, now, stop to pollute my site with your “wisdom” and please find for yourself other avenue where your “healthy thinking” will bring to you more satisfaction.
